Introduction:

Cholesterol granulomas are among the most common benign tumors of the petrous apex and often present with uncharacteristics symptoms. The exposed position presents the ENT surgeon with a number of intraoperative problems, so the choice of the appropriate access route is of particular importance.

Methods:

In the retrospective analysis of cholesterol granulomas of the petrous apex, nine patients were compared with regard to their surgical approach (transsphenoidal vs. infralabyrinthine) and their postoperative symptoms.

Outcome:

In 3 cases where the transsphenoidal approach was chosen, all patients were symptom-free, with the postoperative function of the inner ear as well as of the balance remaining unrestricted. No complaints were also achieved in the 6 patients who underwent surgery via the infralabyrinthine approach. With preserved inner ear function, the treatment of conductive hearing loss with the Vibrant Sound bridge took place in 3 cases, 2 patients received conventional hearing aids and one patient was treated by a TORP.

Discussion:

Both the anatomy of the petrous apex and its pathology should determine the operative approach of the surgeon. In our opinion the navigated transsphenoidal and infralabyrinthine approach both represent a safe alternative.
