title: Sensation recovery of auricle following chronic ear surgery by retroauricular incision.
abstract: The aim of this prospective analysis was to objectify and quantify the sensory loss in the auricular area that occurs following surgery for chronic otitis media or cholesteatoma, and to assess the exact recovery time of the auricular sensation. Till now, no study has yet been conducted on the sensory loss that is developed after retroauricular incision is performed for chronic ear surgery. Forty-eight patients underwent surgery via retroauricular incision for chronic otitis media or for chronic otitis media or cholesteatoma between March 2009 and January 2010. The skin around the auricle was divided into six areas. The sensation of each area was assessed before the surgery and 3 days, 7 days, 1 month, 3 months, and 6 months after the surgery, using the Semmes-Weinstein monofilaments. The patients were also asked to record the sensation that they felt using the visual analog scale (VAS). In the objective sensory assessment, only area 5, which corresponds to the retroauricular area, showed significant sensory loss. Three months after the surgery, the sensation was recovered to a level comparable to that before the surgery in most of the patients. The mean subjective VAS score was 10 prior to the surgery, 8.56 (± 1.08) 3 months after the surgery, and 9.32 (± 0.74) 6 months after the surgery, respectively. In conclusion, following chronic ear surgery, the sensation of the auricle was recovered to the previous level within 3 months. Therefore, patients who are to undergo retroauricular incision should be informed that they will experience temporary sensory loss for approximately 3 months after the surgery.
