Summary
KTP laser meatoplasty offers a fast and effective surgical option for chronic otitis externa, improving hearing and patient satisfaction. This pilot study indicates promising short-term results for canal patency in fibrotic ear conditions.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Laser Applications in Medicine
Background:
- Chronic otitis externa, particularly in its fibrotic stage, presents challenges with traditional meatoplasty.
- Existing meatoplasty techniques often yield variable outcomes in canal patency, hearing improvement, and patient satisfaction.
Purpose of the Study:
- To evaluate the efficacy and safety of KTP laser meatoplasty as a novel surgical technique for chronic otitis externa.
- To assess short-term outcomes including canal patency, hearing gain, and patient satisfaction.
Main Methods:
- A pilot study involving ten KTP laser meatoplasty procedures on eight patients with chronic otitis externa.
- Evaluation of surgical effectiveness, procedure duration, hearing thresholds, and patient-reported satisfaction.
Main Results:
- The KTP laser meatoplasty technique demonstrated effectiveness and speed.
- A high short-term patient satisfaction rate was observed (mean follow-up 9.3 months).
- Average hearing threshold improvement of 24 dB HL was recorded, with significant benefit in six out of eight patients.
Conclusions:
- KTP laser meatoplasty is a promising, fast, and effective technique for chronic otitis externa, offering high patient satisfaction.
- The procedure shows advantages over traditional methods, though long-term efficacy requires further investigation.
