Translabyrinthine approach for acoustic tumor removal

Area of Science:

• Neurosurgery
• Otolaryngology
• Oncology

Background:

• The cerebellopontine angle is a critical anatomical region housing important cranial nerves and vessels.
• Tumor removal in this area presents surgical challenges due to proximity to vital structures.
• Surgical approach selection impacts patient outcomes, including neurological function and recovery.

Purpose of the Study:

• To evaluate the translabyrinthine approach for cerebellopontine angle tumor removal.
• To highlight the advantages of the translabyrinthine approach compared to other surgical routes.
• To assess the safety and efficacy of this technique in specific patient populations.

Main Methods:

• Retrospective analysis of patients undergoing translabyrinthine approach for cerebellopontine angle tumors.
• Detailed review of surgical technique, including facial nerve management and tumor resection.
• Assessment of postoperative complications such as CSF leaks and headaches.

Main Results:

• The translabyrinthine approach offers direct access to the cerebellopontine angle, minimizing cerebellar retraction.
• It facilitates proximal and medial identification and immediate repair of the facial nerve if severed.
• This approach demonstrated the lowest morbidity regarding CSF leaks and postoperative headaches.

Conclusions:

• The translabyrinthine approach is a preferred surgical route for large cerebellopontine angle tumors or in patients with poor hearing.
• It offers significant advantages in terms of nerve preservation, reduced retraction, and lower complication rates.
• This technique contributes to improved patient outcomes and recovery after cerebellopontine angle tumor surgery.
