Stapes surgery at the Otologic Medical Group.

Area of Science:

• Otolaryngology
• Surgical Innovation
• Auditory Health

Background:

• Stapedectomy is a surgical procedure to restore hearing in cases of otosclerosis.
• The choice of oval window covering material can impact surgical outcomes.
• Gelfoam and tissue grafts are common materials used in stapedectomy.

Purpose of the Study:

• To compare the efficacy of tissue grafts versus Gelfoam as oval window coverings in primary stapedectomy.
• To evaluate hearing results, sensorineural hearing impairment, and postoperative dizziness associated with each covering type.

Main Methods:

• Retrospective review of 498 primary stapedectomy cases.
• Analysis of factors including disease duration, age at surgery, oval window pathology, hearing outcomes, dizziness, and tinnitus.
• Comparison of outcomes based on the use of tissue grafts versus Gelfoam for oval window coverage.

Main Results:

• Ninety percent of cases using tissue grafts achieved postoperative hearing within 10 dB of preoperative bone conduction.
• Sensorineural hearing impairment was 2-3 times more frequent with Gelfoam compared to tissue grafts.
• Persistent postoperative dizziness occurred in 2% of cases, being more common in the Gelfoam group.

Conclusions:

• Tissue grafts are superior to Gelfoam for oval window coverage in stapedectomy.
• Tissue grafts lead to better hearing improvement and reduced postoperative complications.
• The findings support the use of tissue grafts for optimized stapedectomy outcomes.
