Aim: (1) To assess the feasibility, safety, and effectiveness of superficial cervical plexus (SCP) block in oral and maxillofacial surgical (OMFS) practice as an alternative to general anesthesia in selective cases. (2) To assess any associated complication specifically related to the procedure. Subjects and Methods: The total number of patients was 10, out of which 6 were male and 4 were female patients. Six patients had incision and drainage of perimandibular space infections, two patients had Level Ib cervical lymph node biopsies, one patient had enucleation of cyst in the body of mandible, one patient had open reduction and internal fixation isolated angle fracture. Informed written consent was obtained from the patients after they had the procedure explained to them. Exclusion criteria included patient's refusal to undergo the procedure under regional anesthesia, allergy to local anesthetic, excessively anxious, and apprehensive patients, significant upper airway compromise warranting an endotracheal intubation to secure airway. All patients had the procedure done by the same operating surgeon. All patients had their surgical procedures under regional anesthesia (SCP block with supplemental nerve blocks) performed by the same surgeon with satisfactory anesthesia and analgesia without any complication. Results: SCP block with concomitant mandibular nerve and long buccal nerve block has a high success rate, low complication rate, and high patient acceptability as shown in the study. Conclusion: The notable anesthetic effect and adequate working time, summed with the low risk of accidents and complications, make this technique a good alternative for sensitive blockage of part of the cranial and cervical regions and have positive outcomes in selective OMFS cases.

Objective: To evaluate, through radiographic and histological analysis, the tissue reaction induced by a biomaterial based on deproteinized bovine bone matrix (DBBM) in the muscle of sheep. sMaterials and Methods: Sixteen sheep were used. The animals underwent surgery to insert polyethylene tubes containing the biomaterial in the muscle of the lower back (ectopic site) and were euthanized after 3 and 6 months. Each sheep received three tubes: Group 1 - sham group (negative control - tube without biomaterial), Group 2 - particulate autogenous bone (positive control), and Group 3 - DBBM biomaterial (GenOx Inorg). The material removed was evaluated by radiographic, macroscopic, and microscopic analysis, descriptively. Results: Macroscopic analysis showed that Group 3 had a greater tissue volume maintenance. Microscopic analysis indicated that Group 1 had a higher concentration of dense, thin collagen fibers (3 and 6 months); in Group 2, there was a decrease in the inflammatory process and the deposition of dense, thin collagen fibers (3 and 6 months); in Group 3, the presence of a dense connective tissue was noted, in which the DBBM particles (3 months) were found. On the periphery of these particles, a deposition of basophilic material was found, indicating the formation of mineral particles and the formation of tissues with osteoid characteristics (6 months). Conclusion: Based on the results obtained, it can be concluded that the biomaterial based on DBBM led to the formation of tissue with similar characteristics to an osteoid matrix in a postoperative period of 6 months. However, none of the groups evaluated showed ectopic bone neoformation.

Background: Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling. Materials and Methods: A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed. Results: The total of 108 cases revealed the average age at presentation of AFO to be 6.3 years in boys and 9.6 years in girls. There was a slight male predilection and AFO lesions most often occurred in the posterior mandible. AFO was almost always associated with an unerupted tooth or teeth. Conclusions: While the recurrence rate of AFO was found to be 5.5%, long-term postoperative clinical and radiological follow-up is advised to ensure no future signs of aggressive recurrence.

Aims: To establish which rhinoplasty method for primary repairing of unilateral cleft lip (UCL) is better. Settings and Design: Two patient groups with cleft lip were compared. Each group was operated on either by McComb's technique as closed rhinoplasty method or by Vissarionov–Kosin technique as an open method. Subjects and Methods: First group included 29 patients and the second consisted of 31. All patients were operated on by single surgeon over 10 years. Randomization was based on wishes and intention of surgeon to use one of two methods. Evaluation of results was based on impartial data, and subjective information collected from respondents with different levels of knowledge about UCL. The objective scale was based on the evaluation of five noticeable residual deformations of nose that usually appear after primary lip-nose surgery: Alar flattening, low position of alar, widening or narrowing of nostril, and deformation of the upper part of nostril rim. Subjective evaluation was based on the opinion of respondents who were ranged every case depending on own judgment.Statistical Analysis: Was performed using Fisher method and Chi-square by Statistica 10.0, StatSoft Inc. Results: Approach with general analysis indicated no difference between two methods. Despite of absence of clear differences between two groups we consider the closed rhinoplasty more favorable due to less damage to alar cartilages and no scars inside nostrils. Conclusions: We think that mentioned scarring may complicate secondary rhinoplasty, which is often needed to correct nose deformation.

Objective: Various techniques have been employed from time to time to achieve maxillomamdibular fixation. Although arch bars provide an effective and versatile means of maxillomandibular fixation, their use is not without shortcomings. However the introduction of intermaxillary fixation screws (IMF) has eliminated many of these issues of arch bars. The aim of the present study was to compare the advantages and disadvantages of intermaxillary fixation screws over the Erich arch bars in mandibular fractures.Materials and Methods: Sixty dentulous patients who reported to Department of Oral and Maxillofacial Surgery, Al-Ameen Dental College and Hospital, Bijapur with mandibular fractures and required intermaxillary fixation as a part of treatment plan followd by open reduction and internal fixation under GA were selected and randomly divided into 2 groups of 30 patients each that is Group A and Group B. Group A included patients who received intermaxillary fixation with Erich arch bars. Group B includes patients who received intermaxillary fixation with IMF Screws. The parameters compared in both the groups included, surgical time taken, gloves perforation, post-operative occlusion, IMF stability, oral hygiene, patient acceptance and comfort and non-vitality characteristics. Results: The average surgical time taken and gloves perforations were more in Group A,the patient acceptance and oral hygiene was better in Group B, there was not much statistically significant difference in postoperative occlusion and IMF stability in both groups. Accidental root perforation was the only limitation of IMF screws. Conclusion: Intermaxillary fixation with IMF screws is more efficacious compared to Erich arch bars in the treatment of mandibular fractures.

Context: The disorder currently accepted as Pierre Robin syndrome/anomaly/sequence (PRS) has been plagued by controversy ever since initially being described. Controversy exists not only about the appropriate terminology and etiopathogenesis of the disorder but also about its management. Therefore, clinical findings and treatment outcomes of a large database of 266 PRS cases were compared with the current state of knowledge in scientific literature related to history, clinical description, diagnostic criteria, epidemiology, theories of oligohydramnios, mandibular catch-up growth, midfacial hyperplasia, and the timing of management. Aims of Part 1: Display disparities of the widely published subject of PRS that exist within the literature. Subjects and Methods: A literature search related to diagnostic criteria was compared to findings of one of the largest PRS databases worldwide. Results: Regarding diagnostic criteria two subdivisions, the Fairbairn–Robin triad (FRT) and the Siebold–Robin sequence (SRS) can be clearly distinguished. Both present with micrognathia and glossoptosis, the former with, the latter, however, without a palatal cleft. Conclusions: According to clear diagnostic criteria, PRS has to be subdivided in the future into FRT and SRS cases, as they may require different treatment approaches.

Context: The disorder currently accepted as Pierre Robin syndrome/anomaly/sequence (PRS) has been plagued by controversy ever since initially being described. Controversy exists not only about the appropriate terminology and etiopathogenesis of the disorder but also about its management. Clinical findings and treatment outcomes of a large database of 266 PRS cases were compared with the current state of knowledge in the scientific literature, relating to history, clinical description, diagnostic criteria, epidemiology, theories of oligohydramnios, mandibular catch-up growth, midfacial hyperplasia, and the early management. Aims of Part 2: Contribute to the sparse scientific knowledge about pathogenesis and involved genetics. Subjects and Methods: An analysis of this large database was conducted focusing on genetic involvement, family history, and the incidence of additional syndromes. Results: Beside of differences related to clinical signs of dyspnea, feeding problems and mortality rates, various concomitant syndromes, and genetic abnormalities were found in cases of Fairbairn–Robin triad (FRT) and Siebold–Robin sequence (SRS), in addition to differences in relation to clinical signs of dyspnea, feeding problems, and mortality rates. Conclusion: Multiple FRT cases presented with various concomitant syndromes and genetic abnormalities, but only one type occurred in two SRS cases. The latter presented a significantly different mortality rate when compared to the FRT subgroup.

Aim: The aims of Part 3 debate the controversial biological theories relating to PRS. Materials and Methods: Oligo-/poly-hydramnios, mandibular catch-up growth, and midfacial hyperplasia, the three in the literature most prevailing theories related to PRS, have been compared and discussed with the findings provided by this large database of 266 Siebold-Robin sequence (SRS) and Fairbairn-Robin triad (FRT) cases. Results: History and clinical findings evaluated in this database refute the first two theories. Although manifold midfacial appearances were demonstrated in FRT cases, a third of all SRS cases presented with mid-facial hyperplasia. Conclusion: The three main biological theories regarding PRS could not be verified after thorough analysis of the database.

Aims of Part 4: To provide a systematic treatment protocol for Fairbairn–Robin triad (FRT) and Siebold Robin sequence (SRS) patients based on clinical findings and experience with 266 PRS cases. Subjects and Methods: A plethora of treatment modalities and their outcome in literature have been compared to those applied in this database and their outcomes.Results: The management of SRS/FRT depends on various factors including compromised airways, feeding difficulties, as well as the sequence of the reconstructive ladder. Conclusion: Based on the novel PRS subdivisions, a stepwise sequential treatment approach is outlined, addressing the particular needs of each disorder systematically.

Introduction: To report a single center's experience in correcting antimongoloid slant in Asian eyes using a minimally invasive approach. Methods: Retrospective analysis of patients undergoing correction for antimongoloid slant at author's center, from 2007 to 2013 formed the study group. Concomitant surgical procedures were recorded. Pre- and post-operative photographs at the longest follow-up visit were analyzed and graded for functional and cosmetic outcomes. Results: A total of 38 patients (76 eyelids) underwent successful correction to correct eyelid malposition. All patients' eyelids underwent exclusive lateral canthoplasty through a small incision in the upper eyelid crease and re-suspension technique, and 6 of them underwent bilateral slant correction simultaneously with additional cosmetic or corrective surgeries including hemifacial microsomia and Crouzon's syndrome. Of the 38 patients, 25 were females and 13 were males. The age of the population ranged from 7 to 48 years with a mean age of 27 years. Few instances of transient postoperative chemosis lasting up to 2 weeks and minor infections were reported. All cases showed improvement in eyelid position (as assessed clinically and on photographs), 2 pediatric cases required reoperation in the following 2 years for the recurrent lower eyelid malposition and/or lateral canthal deformity owing to deviated basal bone growth. Discussion: Lateral canthoplasty with resuspension technique can effectively address antimongoloid slant for an esthetically desirable lateral canthus.

Aim: The aim was to determine the morbidity or mortality associated with the blind awake intubation technique in temporomandibular ankylosis patients. Settings and Design: A total of 48 cases with radiographically and clinically confirmed cases of temporomandibular joint (TMJ) ankylosis were included in the study for evaluation of anesthetic management and its complications. Materials and Methods: Airway assessment was done with standard proforma including Look externally, evaluate 3-3-2 rule, Mallampati classification, Obstruction, Neck mobility (LEMON) score assessment in all TMJ ankylosis patients. The intubation was carried out with the standard departmental anesthetic protocol in all the patients. The preoperative difficulty assessment and postoperative outcome were recorded. Results: Blind awake intubation was done in 92% of cases, 6% of cases were intubated by fiberoptic awake intubation, and 2% patient required surgical airway. Ninety-eight percent of the patients were cooperative during the awake intubation. The frequent complications encountered during the blind awake intubation were epistaxis and sore throat. Conclusion: In an anesthetic setup, where fiberoptic intubation is not available, blind awake intubation could be considered in the anesthetic management algorithm.

Background: Anterior cranial bone defects secondary to global war cranial defects pose a unique reconstructive challenge. The objective of this study was to evaluate the outcomes of alloplastic reconstructions of cranial bone with titanium mesh and fat graft after warfare-related cranial trauma. Patients and Methods: Thirty-five patients at the plastic and reconstructive surgery ward of our hospital underwent anterior cranioplasty with titanium mesh with or without fat grafts from lower abdominal wall. Inclusion criteria were anterior cranial bone defect due to warfare injuries, the mean age of these patients was 31 years (range, 23–48 years). Ninety-five percent were male, and 5% were female. Average follow-up was 12 months. Fat grafts were used to help obliterate endocranial dead spaces. Results: Twenty-five patients (71%) had more than 0.5 cm dead space under cranial defects, and we used fat graft under the titanium mesh. The majority groups of patients (80%) were injured as a result of previous explosive device blasts with or without neurosurgical procedures in the past. The average patient age was 31 years, and 95% of patients were male. The mean anterior cranial defect size was 6 cm × 8 cm, and there were no wound infection or flap necrosis after operations. Conclusion: We recommend this procedure (titanium mesh with or without fat graft) for warfare injured cranial defects in secondary anterior cranial reconstructions. Fat grafts eliminates dead space and reduce secondary complications.

Introduction: A single center's experience of correction of cleft lip/palate associated rhinoplasty using Abbe flap is relatively rare in literature. The outcome and perception of the Abbe flap for cleft rhinoplasty at patient, surgeons, and patient's caregiver level have not been found in literature. This manuscript aims to address this lacuna through the use of rhinoplasty outcomes evaluation questionnaire (ROEQ). Materials and Methods: A retrospective analysis of preoperative satisfaction and prospective analysis of postoperative satisfaction of patients who underwent cleft rhinoplasty were carried out using ROEQ. This was used twice measuring the pre- and post-operative periods. Results: Twenty-one cases of bilateral cleft lip and palate who had earlier undergone (0.5–3 years back) cleft rhinoplasty and lip revision with Abbe's flap formed the study group. The mean age of the 21 subjects was 22.87 ± 4.23 years. There were 13 males and 8 females forming the study group. The mean presurgical ROEQ score was 19.8 ± 11.2, while the postsurgical score was 78.5 ± 21.2. This difference was statistically significant (P = 0.001). The difference in score between the time period was 58.7%. Discussion: From the ROEQ and other qualitative parameters, it is possible to demonstrate the impact of Abbe flap for cleft rhinoplasty and its impact on the quality of life of patients. Most of the patients and caregivers believed that this approach achieved a good or excellent postoperative result. The biological and operators factors behind such a success are discussed in light of previously published literature.

Aims: The aims of the study were to evaluate the efficacy of simultaneous interpositional arthroplasty with distraction osteogenesis (DO) as a single procedure and to give the patient acceptable functional rehabilitation with correction of the gross facial asymmetry. Materials and Methods: Nine patients of temporomandibular joint (TMJ) ankylosis with micrognathia were treated with interpositional arthroplasty and simultaneous DO and followed for a period of minimum 3 years. Preoperative, immediate postoperative, at the end of distraction, at 6 months and 3 years postdistraction consolidation radiographs were taken along with the clinical examination for mouth opening, deviation, length of the mandible and ramus, midline shift, occlusal cant, and occlusion. Results: The results showed an increase in the mouth opening, length of the mandible and ramus height, correction of deviation, occlusion, and midline shift. Relapse was not seen in any case, rather one patient developed infection at the distractor site and two patients had fracture of the roots of the teeth at the osteotomy site. There was an overall improvement in the facial asymmetry. Conclusion: Simultaneous interpositional arthroplasty with DO should be used to correct TMJ ankylosis associated with facial asymmetry/micrognathia, as it reduces the need for second surgery, thereby saving the trauma of a second surgery and difficulty in intubation, increases the length of the mandible, corrects the deformity, thereby resulting in an acceptable facial esthetics and function.

Background: The harvesting of a tooth as a candidate for tooth autotransplantation requires that the delicate dental tissues around the tooth be minimally traumatized. This is especially so for the periradicular tissues of the tooth root and the follicular tissues surrounding the crown. The aim of this report is to describe the use of piezosurgery as an attempt at morbidity reduction in the harvesting of teeth for autotransplantation. Methods: A piezosurgical handpiece and its selection of tips were easily adapted to allow the harvesting and delivery of teeth for autotransplantation purposes. Results: Twenty premolar teeth were harvested using a piezosurgical device. The harvested teeth were subsequently successfully autotransplanted. All twenty teeth healed in a satisfactory manner without excessive mobility or ankyloses. Conclusions: Piezosurgery avoids some of the traumatic aspects of harvesting teeth and removing bone which are associated with thermal damage from the use of conventional rotary instruments or saws. Piezosurgery can be adapted to facilitate the predictable harvesting of teeth for autotransplantation purposes.

The aim of this study is to review and compare survival/success rate of dental implants inserted in autogenous and allogenic bone blocks (ALBs). A PubMed search was performed from January 1990 to June 2014 limited to English language and human studies. Studies that reported treatment outcome of implants inserted in augmented alveolar ridges with autogenous or ALBs were included. Primary search identified 470 studies. For autogenous bone block (ABB) 36 articles and for ALB 23 articles met the inclusion criteria. Evidence on implant survival/success rate of both techniques was limited to observational studies with relatively small sample sizes. Study design, treatment methods, follow-ups, defect location, and morphology varied among studies. The range of implant survival and success rates in ABB was from 73.8% to 100% and 72.8% to 100%, respectively. The corresponding numbers for ALB were 95.3–100% and 93.7–100%, respectively. A definite conclusion could not be reached. Future studies with long-term follow-ups are required to further elucidate this issue.

The purpose of this manuscript is to add some more information in the present scientific literature on these nearly forgotten triangles of surgical importance. The neck is an area that lends itself to anatomical geometry, such as triangles. Many triangles of the neck have been described, and some are well-known, yet, some have been nearly forgotten, i.e., Lesser's triangle, Farabeuf triangle, Pirogoff's triangle, and Beclard's triangle. From the anatomic and surgical point of view, the neck is an amazingly interesting place. It is like a connection where crucial functional units meet and pass. Added surgical landmarks are always helpful to the surgeon while dealing with the neck. Described triangles of neck in this article are always reliable and constant landmarks for head and neck surgeons

Background: Autogenous bone graft harvesting from the iliac crest is associated with donor site morbidity. The aim of this report is to describe the use of piezosurgery as an attempt at morbidity reduction. Materials and Methods: A piezosurgical handpiece and its selection of tips can easily be accommodated in an iliac crest wound to osteotomize and allow the harvest and delivery of autogenous bone grafts. Results: Corticocancellous blocks or cancellous strips of autogenous bone can be readily harvested using a piezosurgical technique at the anterior iliac crest. Conclusion: Piezosurgery avoids some of the traumatic aspects of harvesting bone associated with the use of conventional rotary instruments or saws.

Ameloblastoma is benign odontogenic tumor, which is locally aggressive in behavior. Till date, the treatment of choice is resection and reconstruction using a variety of modalities. Inadequate resection may lead to many complications such as bone deformity and dysfunction. This report is about a 14-year-old male with ameloblastoma treated with autologous dental pulp stem cells (DPSCs) and stromal vascular fraction (SVF) and evidence of bone regeneration. Marsupialization was performed; tooth was extracted and sent for DPSC cultivation. On the day of surgery, SVF was processed from buccal pad of fat, and platelet-rich fibrin (PRF) was prepared from patient's peripheral blood. During the procedure, labial plate resection and curating of tumor lining were done. After which, a mesh packed with SyboGraft T-plug, prepared SVF, DPSCs, and PRF were placed over lingual cortex and pressure dressing was done. After the 1^st month of surgery the postoperative course was uneventful, the wound shrinkage led to exposure of mesh in the intraoral region. Removal of exposed mesh was done. The correction surgery with removal of part of mesh and primary closure was achieved with SyboGraft plug, SVF and PRF. Enhanced bone formation was seen in post-operative OPG and CT Scan after 10^th month. In this article, we propose an innovative approach to manage these cases by using a combination of autologous DPSC and buccal pad of fat SVF to regenerate a mandibular defect left by the resection of an ameloblastoma with 1.5 year follow-up. We were able to demonstrate bone regeneration using this technique with no recurrence of tumor.

Temporomandibular joint (TMJ) Ankylosis is an extremely disabling condition characterized by difficulty or inability to open the mouth resulting in facial asymmetry, malocclusion and dental problems. Surgical excision of the ankylosed mass is the only treatment option available to gain mouth opening. The loss in vertical height of ramus following release of ankylosis is difficult to manage in both unilateral and bilateral TMJ ankylosis. Out of all the methods to restore this height Distraction Osteogenesis (DO) is gaining popularity because of predictable gain in the length without any associated morbidity. Recurrent bilateral TMJ ankylosis in a 32 year old male was treated by osteoarthrectomy and temporal fascia interpositioning arthroplasty. Bilateral reconstruction of ramal condylar unit (RCU) was carried out by Zurich paediatric distractor (KLS Martin, Tuttlingen Germany). Following a latency period of 7 days distraction was carried out at a rate of 1mm/day for 8 days. Distractors were removed after 12 weeks of consolidation period. The case was followed up for 12 months during which the mouth opening was maintained at 38 mm and there was no anterior open bite.

The growth of the craniofacial skeleton takes place from the 3^rd week of intra-uterine life until 18 years of age. During this period, the craniofacial complex is affected by extrinsic and intrinsic factors which guide or alter the pattern of growth. Asymmetry can be encountered due to these multifactorial effects or as the normal divergence of the hemifacial counterpart occurs. At present, an orthodontist plays a major role not only in diagnosing dental asymmetry but also facial asymmetry. However, an orthodontist's role in treating or camouflaging the asymmetry can be limited due to the severity. The aim of this research is to report a technique for facial three-dimensional (3D) analysis used to measure the progress of nonsurgical orthodontic treatment approach for a subject with maxillary asymmetry combined with mandibular angular asymmetry. The facial analysis was composed of five parts: Upper face asymmetry analysis, maxillary analysis, maxillary cant analysis, mandibular cant analysis, and mandibular asymmetry analysis which were applied using 3D software InVivoDental 5.2.3 (Anatomage Company, San Jose, CA, USA). The five components of the facial analysis were applied in the initial cone-beam computed tomography (T1) for diagnosis. Maxillary analysis, maxillary cant analysis, and mandibular cant analysis were applied to measure the progress of the orthodontics treatment (T2). Twenty-two linear measurements bilaterally and sixteen angular criteria were used to analyze the facial structures using different anthropometric landmarks. Only angular mandibular asymmetry was reported. However, the subject had maxillary alveolar ridge cant of 9.96°and dental maxillary cant was 2.95° in T1. The mandibular alveolar ridge cant was 7.41° and the mandibular dental cant was 8.39°. Highest decrease in the cant was reported maxillary alveolar ridge around 2.35° and in the mandibular alveolar ridge around 3.96° in T2. Facial 3D analysis is considered a useful adjunct in evaluating inter-arch biomechanics.

Background: The aim was to introduce and preliminarily evaluate a new software application, SICAT Function, which can directly combine and merge three-dimensional cone beam computed tomography (CBCT) and electronic SICAT jaw motion tracking (JMT) data. Methods: A detailed description of the methods and dynamic clinical simulation of mandibular movements of a patient are demonstrated. Functional jaw movements on 3 days were recorded by JMT tracking system. The simulation was performed by merging CBCT and JMT data in the software SICAT Function suite. The condylar position simulated by SICAT Function suite was compared with real condyle position showed by a CBCT of the patient. Results: The incisor ranges of functional movements were displayed by JMT tracking system. The visualization of patient-specific mandibular movement including the translation of the condyles was displayed after data merge. The recordings of mandibular movements of the patient were similar on 3 different days. The condylar position simulated by SICAT was coincident with real condyle position by CBCT data with the same amount of mouth opening. Conclusions: The SICAT Function software is a system capable of measuring and visualizing patient-specific jaw movement relative to the patient-specific anatomy of the jaw. Further studies are needed to validate its accuracy and its potential for future use.

Gorlin-Goltz syndrome due to its high variability in expression are often not diagnosed as the syndrome and often managed same as that of odontogenic keratocyst. But a more careful approach for the syndrome is needed as there is high chance of malignant changes owing to improper management of the syndrome. In this manuscript a case report of Gorlin-Goltz syndrome with the diagnostic features of the same in Indian population along with the difference in treatment protocol from treating an odontogenic keratocyst is described with review of literature

Tertiary hyperparathyroidism (HPT) is a rare condition that affects patients with secondary HPT, which develop hyperplasia of the parathyroid glands, thus causing an increase in parathyroid hormone levels. Bone alterations are the main consequences of this condition including the development of osteolytic lesions called brown tumor. This article reports an unusual case of brown tumors located in the maxilla and mandible in a 19-year-old man with chronic renal failure with hyperplasia of the parathyroid glands. The lesions regressed approximately 5 months after the parathyroidectomy. At this same time, the patient underwent renal transplant. The patient was followed for 5 years, showing improvement in overall clinical status. There was also improvement of the results of laboratory tests and the pattern of trabecular bone. The correct diagnosis of oral lesions was of great relevance for the conservative treatment could have been chosen.

This report describes the multidisciplinary management of a 35-year-old female sickle-cell anemia patient who had unilateral bony ankylosis of the left temporomandibular joint secondary to septic arthritis. She was managed by a team comprising of maxillofacial surgeons, anesthetists, otorhinolaryngologist, and hematologist. Unilateral left interpositional arthroplasty and ipsilateral coronoidectomy through a postrami approach were done and followed by aggressive jaw physiotherapy in the postsurgical period. No perioperative morbidity was encountered. Mouth opening of 3.5 cm was achieved and maintained 7 months after surgery. Challenges and rationale for the use of a multidisciplinary team approach in treatment of such cases were discussed.

Crouzon syndrome is one of the frequent pathologies within craniosynostosis syndrome. Current progress in computers and biotechnologies allows improving surgical approach and forecasting final result of reconstruction as well. We present a case of successful surgical treatment of Crouzon syndrome, done by application of virtual planning allowing determining “monobloc” features, type of reconstruction and distraction protocol as well. A 20-year-old female had presented with craniofacial deformity. Clinical and radiological investigation revealed Crouzon syndrome. The “monobloc” creation, cranioplasty and internal distractors positioning, direction and schedule of advancement were done according to preoperative virtual planning data achieved by Materialise Mimics Research software. Nine months postoperative functional and esthetic result and radiological findings showed to be reasonable. That application of virtual simulation significantly allows to determine best direction of distraction and improves postoperative outcomes of surgical treatment of Crouzon syndrome.

Teratomas are among the most common tumors of childhood, but craniofacial teratomas are rare. They can be diagnosed antenatally. Craniofacial teratomas may cause airway obstruction in the newborn. We present a case of a newborn male child who was diagnosed to have a facial tumor in the 8^th month of gestation. He was delivered normally and had no respiratory or feeding difficulties. He was also found to have a cleft palate. Serum alpha fetoprotein levels were normal. He underwent excision on day of life 9. At 11 months follow-up, he is well with no evidence of recurrence and good functional outcome.

A case of metastatic renal cell carcinoma (RCC) to the mandible is reported. A 22-year-old man consulted us for hypoesthesia of the right lower lip. Panorama X-ray film showed a radiolucent lesion in the right mandibular body. A diagnosis of a metastatic tumor to the mandible from the right kidney was made after evaluation by computed tomography and bone scan with Tc99 methyl diphosphonate which also revealed multiple bone metastases. Histologically diagnosis was clear cell variant of RCC. Patient has been put on radiotherapy for symptomatic treatment and a molecularly targeted drug. The therapy effectively stopped the progressive growth of oral and other metastatic lesions. The quality of life is relatively well maintained with tolerable adverse effects. The patient is still on our follow-up with an improved quality of life.
