Endoscopic transcanal myringoplasty

Area of Science:

• Otolaryngology
• Surgical Technology
• Audiology

Background:

• Dry central perforation of the tympanic membrane is a common condition requiring surgical intervention.
• Traditional surgical methods may face limitations due to anatomical variations.
• Evaluating tubal function is crucial for successful middle ear surgery.

Purpose of the Study:

• To evaluate the efficacy of the rigid endoscope in managing dry central tympanic membrane perforations.
• To compare the rigid endoscope with the operating microscope for tympanic membrane surgery.
• To assess the impact of rigid endoscopy on graft take rates and audiological outcomes.

Main Methods:

• Retrospective analysis of 36 cases undergoing tympanic membrane perforation repair using a rigid endoscope.
• Pre-operative assessment of tubal function using manometry in conjunction with endoscopy.
• Surgical procedures focused on tympanic membrane closure and graft placement.

Main Results:

• A high graft take rate of 91.7% was achieved.
• Significant closure of the air-bone gap to less than 10 dB in 83.3% of cases.
• The rigid endoscope provided clear visualization and access, overcoming anatomical challenges.

Conclusions:

• The rigid endoscope represents a significant advancement in middle ear surgery for tympanic membrane perforations.
• It offers superior visualization and maneuverability compared to the operating microscope.
• Its use, combined with manometry, aids in evaluating and treating tubal dysfunction, improving surgical success rates.
