The Fully Endoscopic Acoustic Neuroma Surgery

Area of Science:

• Neurosurgery and Otolaryngology
• Minimally Invasive Surgical Techniques

Background:

• Vestibular schwannomas (VS) are tumors typically managed with established surgical methods.
• Intracanalicular VS present unique management challenges due to their location within the internal acoustic canal (IAC).
• The optimal surgical strategy for intracanalicular VS remains a subject of debate.

Purpose of the Study:

• To detail the indications and surgical technique for treating intracanalicular VS using a transcanal/transpromontorial endoscopic approach.
• To present a novel endoscopic-only surgical strategy for cochlear schwannomas involving the IAC.

Main Methods:

• Description of an exclusive endoscopic approach for internal acoustic canal (IAC) tumor removal.
• Surgical technique focused on the transcanal/transpromontorial endoscopic corridor.
• Case study of cochlear schwannoma removal involving the IAC via this endoscopic method (March 2012).

Main Results:

• Successful safe removal of a cochlear schwannoma involving the IAC using the described endoscopic technique.
• Demonstration of the feasibility of an exclusive endoscopic approach for intracanalicular VS.

Conclusions:

• The transcanal/transpromontorial endoscopic approach provides a viable and safe option for selected cases of intracanalicular VS.
• This endoscopic technique has the potential to alter traditional management paradigms for these challenging tumors.
• Further evaluation of this approach in appropriate cases is warranted.
