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 کاملQuantitative anatomic comparison of the extended pterional transtemporal transtentorial approach and the subtemporal transtentorial approach to the petroclival region.
AIM The anatomic characters and applicability of the extended pterional transtemporal transtentorial (EPTT) approach versus the subtemporal transtentorial (ST) approach for surgical treatment of petroclival tumors were evaluated. MATERIAL AND METHODS Ten sides from five adult Chinese injected cadavers were manipulated using both two approaches. Four deep bony anatomic landmarks were specified...
متن کاملMicrosurgical Resection of Petroclival Tumors via the Subtemporal Transtentorial Approach.
AIM To study and summarize our experience with the subtemporal transtentorial approach for resection of petroclival tumors. MATERIAL AND METHODS Twenty-eight patients who suffered from petroclival tumors and underwent tumor resection via a subtemporal transtentorial approach between October 2010 and July 2013 were retrospectively reviewed. RESULTS Total resection was performed in 22 cases, ...
متن کاملSurgical Exposure Gained in an Extended Retrosigmoid Approach to the Cerebellopontine Angle Compared to the Traditional Retrosigmoid Approach.
AIM Retrosigmoid approach to the posterior fossa has been a popular and dependable approach for accessing the cerebellopontine angle (CPA) and petroclival region. Although this approach is commonly used, it requires cerebellar retraction and has limitations when the lesion is located ventral to the brainstem. The aim was to quantify the angle of view provided by extended retrosigmoid approach i...
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...
