Objectives: Extensive fractures involving the anterior and posterior tables of the frontal sinus are treated by frontal sinus cranialization. During this procedure, the disrupted posterior wall of the frontal sinus is removed, the sinus mucosa is drilled away, and the brain and dura are permitted to rest against the repaired anterior wall and sinus floor. Conventionally, the area originally occupied by the frontal sinus is left as dead space or filled with free adipose tissue. We describe a method of cranialization using a pericranial flap and report our experience with this technique.

Study Design: Retrospective study.

Methods: The medical records of patients who underwent frontal sinus cranialization using the pericranial flap at our institution were reviewed. Demographics, indications for cranialization, complications, and perioperative outcomes were examined.

Results: A total of 19 patients underwent (bilateral) frontal sinus …
