Abstract
OBJECTIVE: This study evaluated the graft success rate and hearing outcomes of the inside-out raising mucosal-tympanomeatal flap technique for the repair of large marginal perforations. STUDY DESIGN: Prospective case series. MATERIALS AND METHODS: The study enrolled patients with large marginal perforations who underwent endoscopic cartilage myringoplasty with the inside-out raising mucosal-tympanomeatal flap technique. The graft success rate, hearing outcomes, and complications were evaluated at 12 months postoperatively. RESULTS: In total, 48 patients with large marginal perforations were included. 81% of the population had large perforation, 14.6 had subtotal and total perforation was seen in 4.2%. The mean operation time was 38.6 ± 7.1 min. At 12 months postoperatively, the graft success rate was 89.6% (43/48). The mean air-bone gap was 25.6 ± 5.2 dB preoperatively and 16.5 ± 4.1 dB at 12 months postoperatively, with significant differences between these values (p = 0.001). The functional success rate was 85.4% (41/48). None of the patients experienced worsened sensorineural hearing loss or graft-related complications, such as graft lateralization, significant blunting, and graft medialization, during follow-up. CONCLUSIONS: Endoscopic cartilage-perichondrium myringoplasty for the repair of large marginal perforations using the inside-out raising mucosal-tympanomeatal flap technique was associated with satisfactory graft outcomes and minimal complications.
