Study Design

Case series with chart review.


Tertiary care university hospital.

Subjects and Methods

Pediatric and adult patients with tympanic membrane perforations deemed unfavorable for a medial graft technique due to the perforation characteristics or myringitis.


Between 2014 and 2016, 34 ears from 31 patients underwent a transcanal endoscopic lateral cartilage graft tympanoplasty. The mean age was 24.4 years (range, 6-71 years), and 22 patients (65%) were younger than 18 years. All patients had tympanic membrane perforations. Eighteen patients (53%) had total or near-total perforations, leaving a minimal anterior remnant, and 16 patients (47%) had extensive myringitis. A bisected tragal cartilage-perichondrium shield graft was used in 33 patients (97%). The mean (SD) follow-up length was 9.8 (5.7) months. Initial perforation closure rate was 88.2% (30/34). Three of the persistent perforations underwent a revision endoscopic medial graft tympanoplasty with successful closure, leaving a final closure rate of 97.1% (33/34). Five patients (15%) required topical therapy for postoperative myringitis. Mean (SD) pure-tone average and air-bone gap significantly improved by 11.5 (10.7) dB (P < .001) and 11.4 (10.6) dB (P < .001), respectively. Twenty-seven patients (79%) closed their air-bone gap within 20 dB.


Transcanal endoscopic lateral cartilage graft tympanoplasty is feasible, and initial data support favorable outcomes. Further data are necessary for evaluation of long-term results and efficacy comparisons.
