摘要

Importance Repairing anterior perforations of the tympanic membrane has been challenging for otolaryngologists. Therefore, devising a simple and effective technique for performing the repair is crucial. OBJECTIVE To assess the results of endoscopic transcanal myringoplasty for repairing anterior perforations of the tympanic membrane. DESIGN, SETTING, AND PARTICIPANTS This medical record review included 59 patients who underwent endoscopic transcanal myringoplasty from January 1, 2013, to June 1, 2015, at PoJen General Hospital, Taipei, Taiwan. Patients with ossicular chain disease and cholesteatoma or inadequate follow-up were excluded. Patients were followed up for 6 months, and final follow-up was completed on January 1, 2016. MAIN OUTCOMES AND MEASURES The main outcome was the rate of overall graft success after endoscopic transcanal myringoplasty. Secondary outcomes included hearing results and prognostic factors. RESULTS The study sample included the medical records of 59 patients (30 men [51%]; 29 women [49%]; mean [SD] age, 49.5 [13.1] years) who underwent endoscopic transcanal myringoplasty. Overall, 55 patients (93%) had a successful graft at 6 postoperative months. The mean (SD) preoperative and postoperative air-bone gaps were 15.9 (9.4) and 5.4 (7.0) dB, respectively, revealing a significant mean (SD) improvement of 10.3 (7.6) dB (Cohen d, 1.27; 95% CI, 0.90-1.63; P <.001, paired t test) in the gap. The postoperative air-bone gap in 46 patients (78%) was less than 10 dB; in 12 patients (20%), 10 to 20 dB; and in 1 patient (2%), more than 20 dB. Postoperative otorrhea significantly affected the graft success rate (odds ratio, 52.00; 95% CI, 4.08-662.55; P <.01, 2 test). The visualization of the perforation margin (complete or partial) was not significantly associated with the graft success rate. However, partial visualization of the perforation margin significantly prolonged the mean (SD) operative time (complete vs partial, 59.2 [13.7] vs 68.1 [14.1] minutes; Cohen d, 0.64; 95% CI, 0.12-1.18; P =.02, t test). CONCLUSIONS AND RELEVANCE The rate of graft success and hearing outcomes for endoscopic transcanal myringoplasty are comparable with those of microscopic myringoplasty for repairing anterior perforations of the tympanic membrane. However, the present technique is simpler because postauricular incision, canalplasty, and general anesthesia are not required. Thus, endoscopic transcanal myringoplasty should be considered for repairing anterior perforations of the tympanic membrane.
