Outcomes Following Transcanal Endoscopic Lateral Graft Tympanoplasty

Outcome Objectives: Demonstrate feasibility of performing endoscopic transcanal lateral graft tympanoplasty. Compare audiometric and clinical outcomes of transcanal endoscopic lateral graft with previously reported outcomes of microscopic post-auricular lateral graft tympanoplasty. Methods: A retrospective review of sequential pediatric and adult endoscopic transcanal lateral graft tympanoplasties (type I) performed between May 2014 and August 2015 at a single institution by two experienced otologists. Rate of perforation closure and audiometric outcomes (pure-tone average [PTA] and word recognition scores [WRS]) were obtained and compared with previous published outcomes of post-auricular microscopic lateral grafts. Results: Twenty patients, five right and 15 left ears, met criteria. Ninety percent of patients had successful closure of their perforation. One patient had a residual central perforation; active acute otitis media was noted intraoperatively in this case. One patient had graft lateralization. Mean follow up was 10.5 months (standard deviation [SD] = 141 d). Mean operative time was 160 (SD = 26.1) minutes. Mean improvement in PTA was 18 dB (SD = 10.3). Two patients had worsening of audiometric outcomes with
