Figure 15: (A-H) Bifrontal craniotomy. Exposure of fractured floor of the anterior cranial fossa. (I-M) Debridement of free, unsalvageable bone fragments. Remaining bone of posterior table of frontal sinus bone removed, cranializing the frontal sinus. (N-R) Delicate fragments of cranial floor reapproximated, secured, and fixed. (S-V) Fascia lata graft layered over the sinus and cranial floor to separate and seal off the intracranial cavity above from the sinonasal tract below. (W and X) The free flap sutured with the dura. (Y-AB') Bifrontal bone flap replaced
