Currently, the main application of endoscopic surgery relies on the middle ear cholesteatoma surgical treatment. However, in the natural evolution of the technique there are the steps toward of lateral skull base surgery and treatment of pathologic conditions of pertous bone. The endoscopic approaches to lateral skull base are (1) a transcanal exclusively endoscopic approach or (2) combined app...

The case of a 17-year-old patient with progressive unilateral sensorineural hearing loss and temporal bone malformations concerning for internal auditory canal meningocele with translabyrinthine/perilabyrinthine cerebrospinal fluid fistula is presented with associated computed tomography and magnetic resonance imaging. As the second reported case of an unruptured internal auditory canal meningo...

OBJECTIVES/HYPOTHESIS Image-guided optical tracking systems are being used with increased frequency in lateral skull base surgery. Recently, electromagnetic tracking systems have become available for use in this region. However, the clinical accuracy of the electromagnetic tracking system has not been examined in lateral skull base surgery. This study evaluates the accuracy of electromagnetic n...

Objective To evaluate facial nerve function after excision of petroclival/anterior cerebellopontine angle (CPA) meningiomas by the extended translabyrinthine (EXTL) approach and compare these with outcomes after the transcochlear and transotic approaches. Design Retrospective chart review. Setting/Participants A search of archived surgical cases at a single institution between January 1, 1995, ...

HYPOTHESIS An image-guided robotic system can safely perform the bulk removal of bone during the translabyrinthine approach to vestibular schwannoma (VS). BACKGROUND The translabyrinthine approach to VS removal involves extensive manual milling in the temporal bone to gain access to the internal auditory canal (IAC) for tumor resection. This bone removal is time consuming and challenging due ...

Brain abscess actually remains a threatening pathology despite of medical progress. A delayed brain abscess after an acoustic neuroma surgery by translabyrinthine approach is extremely rare in literature. We describe a case with petrous cavity and cerebellum abscesses by Streptococcus milleri that occurred 3.5 years after the surgical removal of an acoustic neuroma in an 11-year-old child. A hi...

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...
