Summary
Endoscopic tympanoplasty and microscopic tympanoplasty show similar graft success and hearing outcomes for chronic otitis media. Endoscopic surgery offers better cosmetic results, while microscopic surgery may require more canalplasty.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Chronic Otitis Media Research
Background:
- Chronic otitis media (COM) is frequently treated with tympanoplasty.
- Minimally invasive endoscopic techniques are increasingly compared to traditional microscopic approaches.
Purpose of the Study:
- To compare the outcomes of endoscopic tympanoplasty versus microscopic tympanoplasty for COM.
- To evaluate graft success, hearing improvement, and surgical parameters.
Main Methods:
- A prospective comparative study of 312 patients with dry COM perforations from January 2009 to October 2019.
- Patients were divided into two equal groups: 156 for endoscopic tympanoplasty and 156 for microscopic tympanoplasty.
Main Results:
- Graft success rates were comparable: 98.08% (endoscopic) and 93.58% (microscopic).
- Hearing improvement was not statistically significant between groups (p > 0.05), but postoperative hearing improved significantly compared to preoperative levels in both.
- Endoscopic tympanoplasty demonstrated superior cosmetic outcomes, while microscopic tympanoplasty showed higher rates of canalplasty.
Conclusions:
- Both endoscopic and microscopic tympanoplasty yield similar graft success and hearing outcomes.
- Endoscopic tympanoplasty offers advantages in cosmetic results for COM treatment.
