Comparing two different techniques to repair pediatric anterior tympanic membrane perforations

Area of Science:

• Otolaryngology
• Surgical Techniques
• Tympanic Membrane Repair

Background:

• Anterior tympanic membrane perforations present unique surgical challenges.
• Microscopic tympanoplasty (MT) is a traditional approach.
• Endoscopic tympanoplasty (ET) offers a minimally invasive alternative.

Purpose of the Study:

• To compare the outcomes of microscopic overlay (MT) versus endoscopic tympanoplasty (ET) for anterior tympanic membrane perforations.
• To evaluate the efficacy and success rates of both surgical techniques.

Main Methods:

• A retrospective analysis of patients undergoing MT or ET for anterior TM perforations by a single surgeon.
• Comparison of key outcomes including success rate, operating time, and audiological measures.
• Statistical analysis to determine significant differences between the two techniques.

Main Results:

• No significant difference in short-term or long-term perforation closure rates between MT (89.3%, 25.0% failure) and ET (82.9%, 28.6% failure).
• Similar changes in air-bone gap (ABG) and pure tone average (PTA) between the groups.
• While ET patients were older, adjusting for age and follow-up duration did not alter the comparative outcomes.

Conclusions:

• Anteriorly based endoscopic tympanoplasty (ET) is a novel technique for managing anterior TM perforations.
• ET demonstrates comparable efficacy to microscopic tympanoplasty (MT) in this pilot study.
• Further long-term follow-up is warranted to fully establish the role of ET in difficult anterior perforations.
