Background: To retrospectively study the costochondral graft (CCG) based nasal dorsum augmentation failures due to warping. Materials and Methods: All patients fulfilling inclusion and exclusion criteria between January 2008 and December 2011 were included in the study. The details of the dorsal nasal length (DNL) immediate postoperative and 1 week postoperative period as well as the degree of divergence from midline by warping noted down in mm along with age, gender, and nature of graft. Statistics: Data analyzed using Statistical Package for the Social Sciences version 17. Descriptive statistics, Chi-square test and one-way analysis of variance are presented. P value ≤0.05 was considered significant. Result: One hundred and fifty seven cases fulfilled the criteria. Of these, 44 (28%) were males and rest were females. The mean age of the patients was 24.41 ± 4.9 years with a range of 17-37 years. In 102 cases (65%) had soft CCG while 55 (35%) were identified to be gritty type of CCG. Of the 157 cases, warping was identified in 41 cases (26.1%) and required revision of the surgery. Age group was significantly associated with presence of warping ( P = 0.000). Discussion: With increase in age, the number of patients with gritty CCG was higher. Older patients had lesser incidence of warping while younger patients had more incidence of warping. The incidence was not significantly related to gender or the DNL. The grafts that were relatively straight had less incidence of warping.
