[Long term results stape surgery]

Area of Science:

• Otolaryngology
• Genetics
• Audiology

Context:

• Otosclerosis is a complex otologic condition affecting stapes mobility.
• Genetic factors on chromosomes 15q25-q26, 7q34-36, and 6p21-22 are implicated in otosclerosis development.
• Understanding otosclerosis pathophysiology is key to improving surgical outcomes.

Purpose:

• To evaluate the audiometric outcomes of 1380 patients undergoing stapes surgery between 1973 and 2004.
• To assess the effectiveness of stapes surgery in improving air-bone gap for otosclerosis patients.
• To identify factors influencing postoperative hearing results.

Summary:

• Postoperative air-bone gap of 11-20 dB was achieved in 64.8% of patients, with 28.9% achieving less than 10 dB.
• Factors like preoperative hearing loss, disease duration, and patient age influence surgical success.
• Hearing improvement, including the 'over-closure' effect, indicates successful stapes surgery.

Impact:

• Highlights the significant hearing improvement achievable with stapes surgery for otosclerosis.
• Underscores the need for standardized audiometric evaluation post-ear surgery.
• Provides valuable data for clinicians managing otosclerosis patients.
