Summary
Total annulus excision tympanoplasty significantly improves graft uptake and hearing outcomes compared to conventional methods. This technique offers a promising alternative for patients with central eardrum perforations, reducing post-operative discharge.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Auditory Health
Background:
- Tympanoplasty outcomes remain variable despite technique refinements.
- Persistent eardrum discharge is a common post-operative complication.
- Evaluating novel surgical approaches is crucial for improving tympanoplasty success rates.
Purpose of the Study:
- To compare the efficacy of total annulus excision tympanoplasty with conventional underlay tympanoplasty.
- To assess graft uptake, post-operative discharge rates, and hearing improvement.
- To determine if total annulus excision offers superior results for central perforations.
Main Methods:
- A double-blinded, randomized controlled trial was conducted at a tertiary care center.
- 56 patients with central perforations were enrolled and randomized into two groups (28 per group).
- Group A underwent conventional tympanoplasty; Group B underwent total annulus excision tympanoplasty. Patients and evaluators were blinded.
Main Results:
- Total annulus excision tympanoplasty (Group B) demonstrated superior graft uptake compared to conventional tympanoplasty (Group A).
- Patients in Group B experienced significantly less post-operative discharge.
- Greater improvements in air conduction thresholds were observed in Group B (p < 0.05).
Conclusions:
- Total annulus excision tympanoplasty is associated with better graft success and hearing gain.
- This technique effectively reduces post-operative ear discharge.
- Total annulus excision tympanoplasty may be the preferred method for managing central eardrum perforations.
