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 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...
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 کاملTrue petroclival meningiomas: results of surgical management.
OBJECT The relentless natural progression of petroclival meningiomas mandates their treatment. The management of these tumors, however, is challenging. Among the issues debated are goals of treatment, outcomes, and quality of life, appropriate extent of surgical removal, the role of skull base approaches, and the efficacy of combined decompressive surgery and radiosurgery. The authors report on...
متن کاملDevelopmental patterns and characteristic symptoms of petroclival meningiomas.
Thirty-six cases of petroclival meningiomas with clearly defined anatomical features were selected to analyze the site of tumor attachment and the displacement of the trigeminal nerve. The tumors were classified into four categories according to the origin and extension of the tumor: clival origin medial to the trigeminal nerve (upper clivus type), clival origin with dumbbell extension to the c...
