Endoscopic vestibular schwannoma surgery

Area of Science:

• Otolaryngology
• Neurosurgery
• Minimally Invasive Surgery

Background:

• Endoscopic techniques have gained prominence in middle ear pathology treatment.
• Experience in endoscopic skull-base surgery has influenced approaches to the inner ear and lateral skull base.

Purpose of the Study:

• To introduce and evaluate the transcanal transpromontorial approach, an exclusively endoscopic technique.
• To highlight the benefits of endoscopic management for specific vestibular schwannomas.

Main Methods:

• Utilized the external auditory canal as a corridor and the tympanic cavity's medial wall as a surgical window.
• Developed a minimally invasive approach to access structures beyond the middle ear.
• Employed exclusively endoscopic techniques for surgical management.

Main Results:

• The transcanal transpromontorial approach is a viable option for select vestibular schwannoma patients.
• This endoscopic technique is associated with lower intra- and perioperative morbidity.
• Shorter hospital stays were observed compared to traditional surgical methods.
• Endoscopes serve as valuable adjuncts in traditional lateral skull base and inner ear surgeries, enhancing visualization.

Conclusions:

• The transcanal transpromontorial approach offers a less invasive surgical option for certain vestibular schwannomas.
• Endoscopic assistance improves surgical field visualization, aiding in complete tumor resection assessment.
