Abstract
OBJECTIVE: Transcanal endoscopic type 1 tympanoplasty is a minimally invasive procedure that enables better visualization of deep and narrow spaces compared to conventional microscopic methods. In our study, we aimed to evaluate air-bone gap difference, graft success, and hearing gain according to the perforation size and location in pediatric patients who underwent transcanal endoscopic type 1 cartilage tympanoplasty. METHODS: Fifty pediatric patients who underwent transcanal endoscopic type 1 cartilage tympanoplasty for chronic otitis media were included in the study. Tragal cartilage grafts were used in all patients. Air conduction pure tone audiometry hearing results (500, 1000, 2000, and 4000 Hz), mean air-bone gap levels, operating times, postoperative gap closure, and graft success rates were evaluated. RESULTS: Mean operating time was 43.34±8.56 minutes. Overall graft success was 94% (47/50). Mean hearing levels at all frequencies (500, 1000, 2000, and 4000 Hz) were found to have significantly improved after the operation (p<0.001). Mean preoperative air conduction pure tone threshold and mean air-bone gap had statistically significantly improved by the 6th postoperative month (p<0.001). CONCLUSION: Transcanal endoscopic type 1 cartilage tympanoplasty was found to be a minimally traumatic, easy and safe method with a low complication rate. In pediatric patients, this method allows for high rates of anatomic and functional recovery with optimal surgery time regardless of the location and the size of the perforation.
