摘要： 目的 探讨耳垂逆行转位法在低位耳垂型小耳畸形外耳再造中的应用。方法 2014年1月至2015年12月,对20例残耳位置较健侧明显低下的单侧小耳畸形患者,以扩张器法进行外耳再造,一期于残耳后乳突区植入50 m L肾形扩张器,术后1周拆线,并以每周3次的频率进行注水扩张,注水期约1个月。注水完成约1个月后,行二期耳再造术。于二期术中将残耳下缘切开,以残耳上部为蒂,逆行旋转,形成再造耳耳垂,切取残耳的创面直接缝合。结果 20例耳再造术后,再造耳耳垂血运良好。术后随访6~24个月,再造耳外形自然饱满,耳垂位置与健侧基本对称。结论 对于一些严重半侧颜面短小症的患者,残耳位置较健侧明显低下,耳垂逆行转位法可有效矫正再造耳垂位置,使再造耳与健侧耳位置基本对称,形成良好的耳垂形态。

Abstract: Objective To explore the clinical application of remnant earlobe retrograde transposition in the ear reconstruction for microtia with severe low-set ear. Methods From January 2014 to December 2015, 20 cases of unilateral microtia with severe low-set ear were treated. Ear reconstruction was processed with expansion technique. A 50 mL kidney-shaped expander was implanted inside retroauricular region. Saline injection was carried out three times a week. It took one month to complete the saline injection. One month after expansion, ear reconstruction was carried out secondarily. The lower part of the ear remnant was incised to form an earlobe remnant flap, which was retrogradely transposed to reconstruct earlobe. The wound of ear remnant was sutured afterwards. Results No blood supply compromise occurred in 20 cases. All the patients were followed up for 6 months to 2 years, natural appearance and symmetry of bilateral earlobe position were gained. Conclusion In the cases of severe hemifacial microsomia with significant low-set ear, earlobe retrograde transposition can be used to correct the earlobe position and reconstruct earlobe with natural appearance and good symmetry with the other side.
