Autologous Ear Reconstruction for Microtia Does Not Result in Loss of Cutaneous Sensitivity.

Abstract

Cutaneous sensitivity of microtia reconstruction has been sparsely documented. The purpose of this study was to evaluate whether there is a loss of cutaneous sensitivity following two-stage autologous ear reconstruction for unilateral microtia. A prospective study was performed including unilateral microtia patients who underwent two-stage autologous ear reconstruction performed by a single plastic surgeon between 2011 and 2016. Standardized sensory testing (i.e., temperature discrimination and Semmes-Weinstein monofilaments) was executed at 11 predefined anatomical points of the affected and unaffected ears preoperatively and at 6 and 12 months postoperatively. Thirty-eight patients were included. Affected and unaffected sides presented similar (all p > 0.05) preoperative cutaneous sensitivity. Most (72.7 percent) of the tested points showed (all p < 0.05) preservation or recovery of cutaneous sensitivity at 12 months postoperatively. When comparing the reconstructed ears with the unaffected ears, there was no significant difference (all p > 0.05) in most (72.7 percent) of the tested points, except (all p < 0.05) at those points involving the postauricular sulcus. There is a temporary cutaneous sensitivity loss after a two-stage autologous microtia reconstruction, which returned to similar preoperative sensitivity at 12-month follow-up, except in the postauricular sulcus.
