Retrosigmoid-transtentorial approach for petroclival meningiomas: operative technique and clinical outcome
Background: Petroclival meningiomas (PCMs) are technically challenging lesions. Although the standard retrosigmoid approach is one of the most effective approaches, this route may have some limitations for the tumors extending into the supratentorial region and middle cranial fossa. We provide a modified surgical technique called retrosigmoid-transtentorial approach (RTTA) to solve these proble...
متن کاملDetermination of the Keyhole Position in a Lateral Suboccipital Retrosigmoid Approach
Appropriate placement of the keyhole at the transverse and sigmoid sinus (T/S) junction is important for performance of safe and accurate lateral suboccipital craniotomy with minimum bone loss. Here, we report a method for predicting the position of the T/S junction and investigate the relationship between the T/S junction and asterion. The subjects were 88 patients treated surgically via a lat...
متن کاملCombined supra/infratentorial approach to tentorial meningiomas.
In spite of significant advancements in imaging technology, monitoring, and microsurgical techniques, complete and safe removal of tentorial meningiomas remains a challenge for most neurosurgeons. Classifications of tentorial meningiomas are revised. The combined supra/infratentorial approach to resect tentorial meningioma is discussed. This approach provides a wider exposure of the supra/infra...
متن کاملThe Retrosigmoid Suboccipital Approach to Tumours of the Cerebellopontine Angle
Tumours of the cerebellopontine angle (CPA) account for 5% to 10% of all intracranial neoplasms. Various surgical approaches are possible for providing access to tumours of the CPA. The retrosigmoid approach to the posterior cranial fossa is the latest of numerous modifications of the classic suboccipital approach originally popularized by Harvey Cushing. The aim of this review is to discuss th...
متن کاملCurrent Management of Petroclival Meningiomas
Lesions of the petroclival area have long been considered by neurosurgeons as unreachable,I,2 and until recently, patients afflicted with meningiomas in this region have carried poor prognoses, usually with a lethal outcome.1,39 Refined approaches and advances in microsurgery techniques, along with the aid of intraoperative monitoring, have encouraged neurosurgeons to reevaluate the ef1icacy of...
