目的探讨应用Medpor支架行全扩张法耳郭再造术的手术方法和安全性。方法自2012年以来,对12例Ⅱ°或Ⅲ°先天性小耳畸形患者,采用Medpor支架行全扩张法全耳再造术。该手术方法分3期:Ⅰ期手术于患侧乳突区深筋膜下放置70 ml或80 ml肾形扩张器,术后10 d开始适当超量注水;Ⅱ期在扩张区域深筋膜和骨膜之间植入Medpor支架,并根据健侧耳郭调整支架形态及位置,应用扩张的筋膜皮瓣完整包裹支架;Ⅲ期去除无用残耳软骨,行耳垂转位,加深耳甲腔。结果随访6~12个月,术后再造耳郭形态良好,色泽与对侧无异,无感染、支架外露等并发症发生。12例患者中,10例患者对再造耳郭满意或比较满意;1例患者术后颅耳角缩小;另1例患者对术后头皮瘢痕不满意。结论应用Medpor支架行全扩张法全耳再造术,手术操作简便快捷,术后再造耳郭形态良好,无感染、支架外露等并发症,是一种值得深入研究和尝试的术式,其远期疗效及安全性有待进一步观察。 Objective To investigate the surgical methods and safety of total auricular reconstruction with Medpor stent. Methods From 2012 onwards, 12 cases of congenital malformations of otorhinolaryngology Ⅱ ° or Ⅲ ° were treated with Medpor scaffold for total auricular reconstruction. The operation method is divided into three phases: stage Ⅰ operation in the contralateral mastoid area under the deep fascia placed 70 ml or 80 ml kidney-shaped dilator, 10 d after the beginning of appropriate overfill water; Ⅱ in the dilatation zone deep fascia and Medpor scaffolds were implanted between the periosteum, and the shape and position of the scaffolds were adjusted according to the contralateral ear acupuncture. The scaffolds were completely covered with the expanded fascia flap. Stage III was to remove the useless residual cartilage, and the ear lobes were rotated to deepen the cavum. Results The patients were followed up for 6 to 12 months. The auricular reconstruction was performed well after surgery. The color was the same as that of the contralateral side, and no complications such as infection and scaffold exposure were found. Among the 12 patients, 10 patients were satisfied or satisfied with the reconstruction of auricles; one patient had a reduction in the size of the craniofacial ear; the other patient was not satisfied with the scalp scar. Conclusion Medpor stent is a kind of operation which is worth to be researched and tried for further. It is a kind of surgical procedure that should be thoroughly researched and tried in this paper. Efficacy and safety needs further observation.
