Endoscopic Transsphenoidal Approach to Petrous Apex Cholesterol Granuloma

Endoscopic Transsphenoidal Approach to Petrous Apex Cholesterol Granuloma

Study Background: Cholesterol granulomas of the petrous apex are inflammatory reactions following obstruction of air cells within the petrous apex with subsequent transudation of blood and liberation of cholesterol that stimulates foreign body reactions resulting in granuloma formation.

Methods: We report three cases of petrous apex cholesterol granulomas that were treated via the endoscopic transsphenoidal route.

Results: The study included 3 patients (2 males, and 1 female). The patients were completely asymptomatic during the 24 months follow up period with no recurrences or complications.
