title: Sensibility of the ear after otoplasty.
abstract: Changes in skin sensibility occur in various postoperative plastic surgeries, especially when they involve major skin and subcutaneous dissection. There were no studies so far that objectively compared changes of ear sensibility. This prospective study was conducted to compare ear sensibility before and after otoplasty. Patients with prominent ears (n = 15) underwent bilateral otoplasty. Ear tactile sensibility was tested preoperatively and 6 and 12 months after surgery by Pressure Specified Sensory Device, an apparatus that quantifies cutaneous pressure sensation (g/mm(2)). Comparison between preoperative and 6-months postoperative results indicated an increment on mean skin pressure thresholds; however, mean thresholds between pre- and 12 months postoperative period were similar. Vibratory and hot/cold sensibility did not present any difference during this period. This is the first comparative assessment of ear tactile sensibility using quantitative methods. After otoplasty, initially there was reduction in an ear tactile sensibility, followed by a return to levels similar to preoperative sensibility.
