Abstract:
Objective:To investigate the clinical effect of reconstructed tragus with hinge-shaped cartilage flap during the third stage reconstructive surgery in patients with microtia.Methods:From January 2018 to January 2019, the data of the patients with unilateral microtia of residual ear Type Ⅲ treated in the Seventh Department of Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences were analyzed retrospectively. The residual ear tissue preserved in the second stage operation was used to reconstruct the tragus during the third stage operation, and the external auditory meatus was simulated with medium-thickness skin grafting. Postoperative changes were observed in the width, height, and symmetry of the tragus.Results:A total of 31 children with microtia were included, including 19 males and 12 females, aged from 6 to 14 years (mean 8 years), right ear ( n=16) and left ear ( n=15). Postoperative blood supply was good, and the incisions healed primarily. The patient’s immediate postoperative tragus width and height were slightly greater than the preoperative design requirements. After follow-up of 3-6 months, the width of the contralateral tragus was (1.05±0.12) cm, while the reconstructed tragus width was (0.98±0.17) cm. The difference was not statistically significant ( P=0.328). The height of the contralateral tragus was (0.53±0.08) cm, while the reconstructed tragus width was (0.55±0.08) cm. The difference was not statistically significant ( P=0.741). The reconstructed tragus had a good three-dimensional structure and stable shape, and the simulated shape of the external auditory meatus was good. Patients can wear earphones to meet the needs of daily life. Conclusions:Using residual ear cartilage to reconstruct the tragus by flapping hinge-cartilage can improve the three-dimensional structure of the auricle and skin grafting to the concha cavity posterior to the tragus can simulate external auditory meatus. The reconstructed ear resembles the healthy one and meets the need of wearing earphones.
