摘要目的 探讨应用颌颈部皮肤超量扩张预制皮瓣进行面颊部亚单位美学修复的方法和临床效果.方法 靠近面颊部损伤区域的下缘即颌颈部埋置单个容量为100～150 ml的扩张器,对其进行3～5倍额定容量的超量扩张,平均约4个月完成扩张;间隔约半个月后进行面颊部损伤切除,扩张皮瓣转移修复缺损,观察皮瓣成活情况及临床效果.结果 17例面颊部损伤均成功修复,随访3～12个月,皮瓣颜色、质地与周围匹配且能够进行正常的表情活动.结论 超量扩张颌颈部皮肤预制皮瓣能够很好地进行面颊部美学亚单位的修复,是一种实用且符合颜面部美学要求的修复方法.

abstractsObjective To explore a method for repairing the appearance and function of the cheek aesthetic unit.Methods A single volume of 100 ml to 150 ml of tissue expander was implanted at the lower edge of the injury area on the cheek.The first injection was performed 5 days after the operation and twice a week after the injection.It took an average of about 4 months to complete the expansion,with 3-5 times over expanded.The lesions were resurfaced with the expanded flaps,and long term follow-up was observed for flap survival.Results 17 cases of cheek lesions had been successfully reconstructed,with the color,texture of the expanded flaps well matched to the surrounding skin after 3-12 months follow-up.The facial expression functions and configurations were satisfied.Conclusions Excessive expansion of the prefabricated skin flap of the jaw and neck can repair the cheek aesthetic unit successfully,which is a practical method and meets the needs of aesthetic unit repair.
