Summary
Endoscopic tympanoplasty shows comparable success rates to microscopic tympanoplasty but offers better outcomes for postoperative complications and reduced surgical time. This makes endoscopic ear surgery a valuable alternative.
Area of Science:
- Otolaryngology
- Surgical Innovation
Background:
- Endoscopic ear surgery is an established technique.
- Microscopic tympanoplasty is a traditional approach.
Purpose of the Study:
- Compare endoscopic versus microscopic tympanoplasty.
- Evaluate efficacy and safety outcomes.
Main Methods:
- Systematic literature search of four databases.
- Meta-analysis of 33 randomized controlled or observational studies (2646 patients).
- Assessed graft failure, air-bone gap, and postoperative complications.
Main Results:
- Comparable success rates (graft failure, air-bone gap) between endoscopic and microscopic tympanoplasty.
- Endoscopic technique showed significantly lower rates of wound infection, dysgeusia, otitis externa, and numbness.
- Endoscopic surgery had a shorter duration compared to the postauricular microscopic approach.
Conclusions:
- Endoscopic tympanoplasty is a viable alternative to microscopic tympanoplasty.
- Endoscopic approach yields superior results in reducing postoperative complications.
- Endoscopic tympanoplasty significantly decreases surgical duration.
