Transvestibular approach to the internal auditory canal

Area of Science:

• Neurosurgery
• Otolaryngology
• Skull Base Surgery

Background:

• Ménière's disease presents significant challenges.
• Acoustic neuromas require precise surgical intervention.
• Facial nerve decompression is crucial in specific otological conditions.

Purpose of the Study:

• To detail a versatile surgical approach to the internal auditory canal.
• To outline its utility in managing Ménière's disease, acoustic neuromas, and facial nerve decompression.

Main Methods:

• The described surgical technique involves accessing the internal auditory canal.
• It facilitates destructive procedures, diagnostic exploration, tumor removal, and nerve decompression.

Main Results:

• The approach proved effective in Ménière's disease management.
• It enabled simultaneous tumor removal during diagnostic procedures for suspected acoustic neuromas.
• Successful removal of small intracanalicular neuromas and complete facial nerve decompression were achieved.

Conclusions:

• This surgical approach offers a flexible and effective solution for various internal auditory canal pathologies.
• It is beneficial for Ménière's disease, acoustic neuroma management, and facial nerve decompression when hearing is not serviceable.
