目的探讨先天性小耳畸形扩张法耳再造术预扩张的方法及相关问题。方法本组患者418例,均行局部皮瓣预扩张术,术前设计选用改良后扩张器,术中注意剥离层次及范围,止血彻底,术后早期自行注水,适当固定。结果 407例患者扩张器均扩张良好,5例出现感染,6例扩张皮瓣局部破溃,经及时处理后均能继续扩张。Ⅱ期手术后血运良好,再造耳郭外观轮廓较理想。结论采用改良后扩张器及术中、术后的综合处理治疗措施后,扩张效率较高,安全性好,为Ⅱ期耳再造手术打下了良好的基础。
Objective To explore the methods and related problems of pre-dilatation of auricular reconstruction with congenital malformations. Methods 418 cases of this group were undergone local flap pre-dilatation, preoperative design and use of modified dilator, pay attention to the level and scope of stripping surgery to stop bleeding completely, early after the injection of water, appropriate fixation. Results In all the 407 patients, the dilators were well dilated, 5 cases were infected, and 6 cases of dilated flaps were locally ruptured. After prolonged treatment, dilators were able to continue to expand. Ⅱ blood flow well after surgery, reconstruction of ear contour appearance is more satisfactory. Conclusion The improved dilator and intraoperative and postoperative comprehensive treatment of treatment measures, the expansion of high efficiency, good safety, and for the second phase of ear reconstruction surgery has laid a good foundation.
