Otosclerosis surgery: approaches, profits and complications

Area of Science:

• Otolaryngology
• Surgical Innovation
• Audiology

Background:

• Otosclerosis is a common cause of conductive and mixed hearing loss.
• Stapedoplasty is a surgical procedure to restore hearing in otosclerosis patients.
• Evaluating surgical techniques and outcomes is crucial for patient care.

Purpose of the Study:

• To systematically analyze stapedoplasty outcomes in otosclerosis.
• To compare the effectiveness of different surgical approaches and techniques.
• To identify factors influencing surgical success and recommend appropriate hearing aids.

Main Methods:

• A retrospective analysis of 107 otosclerosis patients undergoing stapedoplasty between 2005-2008.
• Data collected on patient demographics, hearing loss type, surgical approach (endaural vs. transmeatal), and technique (stapedotomy vs. stapedectomy).
• Post-operative air/bone gap measurements and complication rates were assessed.

Main Results:

• The endaural approach showed advantages over the transmeatal approach.
• Stapedotomy yielded better surgical outcomes compared to stapedectomy.
• 83.8% of operated ears achieved total or near-total closure of air/bone gaps; only 0.9% experienced definite failure.
• Complications included external ear tube intumescences (20.6%) and facial nerve malposition (1.9%).

Conclusions:

• Stapedotomy is a preferred surgical technique for otosclerosis, offering high success rates.
• The endaural approach is advantageous for stapedoplasty.
• Bone-conduction hearing aids are recommended for residual hearing loss, while air-conduction aids may benefit mixed hearing loss cases.
