Summary
Transcanal endoscopic ear surgery (TEES) for type-1 tympanoplasty in children shows superior tympanic membrane closure rates and better hearing outcomes compared to traditional microscopic approaches. This minimally invasive technique offers improved results for pediatric patients undergoing eardrum repair.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Minimally Invasive Surgery
Background:
- Type-1 tympanoplasty repairs the tympanic membrane without ossicular reconstruction.
- Historically, microscopic approaches with incisions were standard.
- Transcanal endoscopic ear surgery (TEES) offers an incisionless alternative.
Purpose of the Study:
- To compare outcomes of TEES versus non-TEES type-1 tympanoplasty in pediatric patients.
- Evaluate differences in tympanic membrane closure rates.
- Assess post-operative audiometric results between the two surgical approaches.
Main Methods:
- Retrospective review of pediatric patients (2016-2020).
- Comparison of TEES and non-TEES groups for closure rates and audiometry.
- Statistical analysis using Fisher's Exact, Mann-Whitney U, logistic, and linear regression.
Main Results:
- 118 patients: 85 TEES, 33 non-TEES.
- Higher closure rate in TEES group (91.76%) vs. non-TEES (69.7%) (p=0.006).
- Greater reduction in post-operative PTA in TEES group (median -9 dB) vs. non-TEES (median -5 dB) (p=0.015).
Conclusions:
- TEES type-1 tympanoplasty demonstrated superior tympanic membrane closure rates in pediatric patients.
- Audiometric outcomes were also significantly better with the TEES approach.
- TEES is an effective and advantageous technique for pediatric type-1 tympanoplasty.
