Summary
The over-under myringoplasty technique shows a high success rate for repairing tympanic membrane perforations. This method results in excellent graft take and significant hearing improvement with minimal complications.
Area of Science:
- Otolaryngology
- Surgical Techniques
- Audiology
Background:
- Chronic tubotympanic suppurative otitis media frequently causes dry central tympanic membrane perforations.
- Myringoplasty is a surgical procedure to repair tympanic membrane perforations.
- The over-under technique is a specific method for myringoplasty.
Purpose of the Study:
- To evaluate the efficacy of the over-under myringoplasty technique.
- To determine the graft take rate, complication incidence, and hearing improvement after this procedure.
Main Methods:
- A quasi-experimental study was conducted.
- 68 patients with dry central tympanic membrane perforations were enrolled.
- The over-under myringoplasty technique was employed for repair.
Main Results:
- A high graft take rate of 97% was observed at six months.
- Significant hearing improvement occurred in 98.5% of patients, with an average air-bone gap reduction of 12.65 dB.
- Complications such as delayed perforation (3%) and atelectasis (1.5%) were infrequent; lateralization did not occur.
Conclusions:
- The over-under myringoplasty technique is highly effective for tympanic membrane perforation repair.
- The procedure is associated with a high graft success rate and considerable hearing gain.
- It offers a safe and effective surgical option with a low complication profile.
