Placement of Biodesign Otologic Repair Graft During Pinnaplasty to Prevent Suture Extrusion: A Single‐Centre Retrospective Audit

INTRODUCTION: Pinnaplasty is a widely performed procedure to correct prominent ears. A known complication is suture extrusion, which may delay recovery and require revision surgery. OBJECTIVE: To assess whether the placement of Biodesign Otologic Repair Graft over Mustardé sutures reduces the rate of suture extrusion. METHODS: This was a retrospective single-centre clinical audit of 54 consecutive patients (aged ≤ 18 years) who underwent pinnaplasty by a single surgeon between 2011 and 2024. Patients were grouped according to whether Biodesign Otologic Repair Graft was used, and all were followed for up to 12 months post-operatively. The primary outcome was suture extrusion; secondary outcomes included revision surgery and other complications. RESULTS: Suture extrusion occurred in 7/216 sutures (3.24%) in the non-Biodesign group and 0/126 sutures (0%) in the Biodesign group (p = 0.047). One patient in the Biodesign group developed a keloid requiring revision. CONCLUSION: The use of Biodesign Otologic Repair Graft was associated with a reduced rate of suture extrusion in this single-centre audit, with minimal complications. Larger prospective studies are needed to assess cost-effectiveness, long-term safety and generalisability.
