Transmastoid retrosigmoid approach to the cerebellopontine angle: surgical technique.
BACKGROUND The traditional suboccipital craniotomy in the retrosigmoid approach gives limited exposure to the cerebellopontine angle (CPA) structures and necessitates cerebellar retraction, whereas the addition of drilling of the mastoid process with reflection of venous sinuses offers wider exposure of the CPA and avoids cerebellar retraction. We describe the details of the surgical technique ...
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...
متن کاملSurgical Outcomes of Cerebellopontine angle Tumors in 50 Cases
Introduction: To report our experience with a large series of surgical procedures for removal of cerebellopontine angle (CPA) tumors using different approaches. Materials and Methods: This was a retrospective analysis of 50 patients (mean age, 49 years) with CPA tumors (predominantly acoustic neuroma) who underwent surgical removal using appropriate techniques (principally a translabyrinthine...
متن کاملChronic granulomatous abscess simulating cerebellopontine angle tumor.
The delayed development of brain abscess associated with a retained intracranial foreign body is not rare and has been documented [1-5] . We report an unusual case of chronic granulomatous abscess in the cerebellopontine angle region secondary to retention of a cotton ball during surgery for an acoustic neurinoma 20 years earlier. We describe the computed tomographic (CT) findings and emphasize...
