Abstract Objective: The aim of this study was to evaluate the outcomes of this minimally invasive tympanomeatal incision technique performed during endoscopic transcanal cartilage tympanoplasty. Study design: Prospective clinical study. Methods: Eighty-seven patients (87 ears) who had TM perforation with noncomplicated COM were included. All of the patients were operated with the endoscopic transcanal cartilage tympanoplasty technique. All of the data were prospectively collected. These included demographic data, date of the surgery, preoperative and postoperative pure-tone audiometry (PTA), localization of TM perforation and graft healing success. Results: Mean follow-up time was 14.76 ± 4.32 months. Graft-healing rate was 100%. Mean air bone gap level improvement (dB HL) at 0.5, 1, 2 and 4 kHz were 13.87 ± 7.30 dB HL, 9.09 ± 7.59 dB HL, 9.74 ± 6.40 dB HL and 7.46 ± 6.37 dB HL, respectively. At all frequencies, there was significant difference between pre and postoperative mean air bone gap levels (p < .05). There was no significant correlation between the postoperative mean air bone gap level improvement and the localization of the perforation (p > .05). Conclusions: Endoscopic ear surgery has successful surgical outcomes with low complication rates. In this study, the outcomes of limited tympanomeatal flap incision was discussed. It is suggested that this technique is reliable with good hearing results with low postoperative complications rates.
