추체사대 수막종에서 청력을 보존하는 Transcrusal접근법

Hearing preservation with the Trancrusal Apprach to the Petroclival meningioma

To resect of the tumors involving the petroclival region in the cerebellopontine angle and ventral to the brain stem have been a surgical challenge for many years. Multiple cranial nerves and blood vessels may be intimately involved with the tumor. We present the case of a 50 year-old female presenting with symptomatic petroclival meningioma treated by transcrusal approach. Hearing in the operated ear improved within 5months after surgery. We conclude that transcrusal approach is a safe and effective approach to the petroclival region. This approach affords the best chance of hearing preservation and an opportunity for maximum tumor resection.
