摘要目的 探讨全扩张皮瓣法矫正小耳畸形一期手术的操作要点、常见并发症的处理及临床体会.方法 回顾分析了2016年6月至2017年6月,西安交通大学第一附属医院整形美容颌面外科收治的211例小耳畸形患者,行全扩张皮瓣法再造耳廓一期手术的相关资料,对术后并发症进行分析,对现有技术进行改进.结果 本组211例患者,共出现并发症10例,其中血肿4例,扩张器外露3例,感染2例,皮瓣远端血运障碍伴头部剧烈疼痛1例.血肿经冲洗引流后得以清除;扩张器外露病例经彻底清创、重新缝合后扩张器得以还纳;感染经局部灌注及全身使用有效抗生素后得以控制;皮瓣远端血运障碍伴头部剧烈疼痛经减少注射容量后得以缓解.3个月后,211例患者均顺利实施二期耳廓再造手术,术后效果满意.结论 一期手术是全扩张皮瓣法矫正小耳畸形的关键,严格把握手术要点,正确认识并及时处理术后并发症,或可使其不影响后续手术的顺利开展.
