Summary
This study introduces the "empty tympanic membrane" technique for tympanoplasty, achieving a 100% perforation healing rate and improved hearing. This method offers a promising alternative for tympanic membrane repair without complications.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Auditory Health
Background:
- Traditional tympanic membrane repair techniques often involve tamponade and support, which can complicate the procedure.
- The "empty tympanic membrane" technique aims to simplify tympanoplasty by omitting these supportive materials.
Purpose of the Study:
- To evaluate the clinical efficacy of the "empty tympanic membrane" sandwich method in tympanoplasty.
- To assess the healing rate and hearing recovery following this novel surgical approach.
Main Methods:
- A retrospective analysis of 56 patients (59 ears) who underwent tympanoplasty using the "empty tympanic membrane" sandwich technique.
- Data collected included perforation healing rates and hearing thresholds (airway mean hearing threshold and Air-Bone Gap) at 6 months post-surgery.
Main Results:
- All perforations healed completely (100%) with no recurrence.
- Significant improvement in hearing was observed, with postoperative mean hearing threshold (34.4±16.8 dB HL) lower than preoperative (43.6±14.0 dB HL) (P<0.01).
- Postoperative Air-Bone Gap (15.7±10.9 dB HL) was significantly reduced compared to pre-operation (23.0±7.7 dB HL) (P<0.01).
Conclusions:
- The "empty tympanic membrane" technique demonstrates a high success rate for tympanic membrane repair.
- This method leads to excellent hearing improvement and avoids complications like secondary perforation or persistent ear fullness.
- The technique is recommended for widespread clinical application due to its effectiveness and simplicity.
