Background: Petroclival meningiomas are posterior fossa tumors located medial to the fifth cranial nerve and pose different surgical challenges. Objective: This study aimed to review a surgical series of petroclival meningiomas and the factors considered in the choice of approach.

Methods: Retrospective review of 22 petroclival meningioma patients.

Results: Retrosigmoid approach was used in tumors <3 cm and in those at or below the internal auditory meatus. Posterior petrosectomy was performed for tumors extending into the middle fossa. Gross-total resection was performed in 11 patients (50%). The mean follow-up time was 32 months (6–75 months). There were four cases of tumor progression or recurrence, which were treated with radiosurgery.

Conclusion: Resection of petroclival meningiomas remains challenging. In most cases, the retrosigmoid approach was sufficient, without affecting the degree of tumor resection. Petrosal approaches were reserved for patients with tumor extension into the middle fossa.
