A long-term morphometric analysis of auricular position post-otoplasty

Abstract

Otoplasty is a common procedure to correct the shape and position of the external ear. Some surgeons have recommended overcorrection to ensure adequate long-term results but objective data are lacking in this regard. The aim of this study was to measure long-term outcomes of ear protrusion in children after otoplasty. All paediatric patients who underwent otoplasty from July 2009 to June 2011 were enrolled. Measurements of ear prominence at four distinct sites were taken intra-operatively and at 3 and 12 months postoperatively. Data were analysed with repeated measures analyses. A total of 33 patients were included in the study, representing 63 ears. Mean age at surgery was 62.7 months; 20 patients were male and 13 were female. Participants underwent specific otoplasty techniques depending on the underlying anomaly (Mustardé suture placement, conchomastoid suture placement, conchal cartilage resection and/or lobular setback). Overall, there was no statistically significant postoperative change in any of the four measurements over time, indicating stability of the immediate postoperative result. No difference was also noted in any of the four measurements on the basis of patient variables or techniques used. Long-term auricular position, post-otoplasty, was found to be stable in our paediatric patient population, and therefore surgical overcorrection in the operating room is not deemed to be necessary.
