Step-by-Step Stapedotomy through Transcanal Exclusive Endoscopic Approach

Area of Science:

• Otolaryngology
• Minimally Invasive Surgery
• Otology

Background:

• The use of endoscopes in treating middle ear pathologies, including otosclerosis, is increasing.
• Studies show endoscopic stapes surgery yields similar hearing outcomes and low complication rates compared to microscopic techniques.

Purpose of the Study:

• To detail the surgical procedure for transcanal exclusive endoscopic stapedotomy.
• To provide technical guidance for surgeons performing endoscopic stapes surgery.

Main Methods:

• Step-by-step description of the transcanal endoscopic stapedotomy procedure.
• Includes operating room setup, patient positioning, surgical maneuvers, and post-operative care.
• Highlights technical tips for managing challenges like bleeding and instrument handling.

Main Results:

• Endoscopic stapes surgery is effective for otosclerosis, especially in cases with difficult anatomy or revisions.
• Benefits include reduced chorda tympani manipulation and lower rates of post-operative dysgeusia.
• Challenges such as one-handed instrument manipulation and bleeding control can be overcome with proper training and technique.

Conclusions:

• Endoscopic stapes surgery is a viable and beneficial alternative for treating otosclerosis.
• Proper surgical technique, instrument positioning, and team collaboration are key to successful outcomes.
• Training in endoscopic ear surgery is advised for surgeons new to this approach.
