Stapedectomy - a 10 year review at Sunnybrook Hospital

Area of Science:

• Otolaryngology
• Surgical Outcomes
• Hearing Restoration

Background:

• Stapedectomy is a common surgical procedure for hearing loss.
• Outcomes can vary between surgical centers and individual surgeons.
• Evaluating local hospital success rates against major centers is important for quality assessment.

Purpose of the Study:

• To assess the success rate of stapedectomy performed by surgeons in a local general hospital.
• To compare these results with those reported from major specialized centers.
• To identify factors influencing stapedectomy outcomes.

Main Methods:

• A 10-year retrospective review of 160 primary stapedectomy and revision stapedectomy cases.
• Data collected included surgical success rates, patient demographics, and prosthesis types.
• Analysis focused on favorable and unfavorable outcomes, and surgeon/prosthesis variability.

Main Results:

• Primary stapedectomy achieved a 78% favorable result and 8% unfavorable result.
• Older patients with more affected footplates had worse outcomes.
• Revision stapedectomy yielded significantly worse results: 21% favorable and 42% worsening hearing.

Conclusions:

• Stapedectomy outcomes at a general hospital are comparable to major centers for primary procedures.
• Revision stapedectomy has a lower success rate and higher risk of hearing worsening.
• A conservative approach to revision stapedectomy is recommended.
