摘要
目的探讨中重度小颏畸形的综合美容整形方法。方法手术采用口内入路,于下唇唇龈沟唇侧黏膜设计“V”形切口,切开黏膜的长度约为4cm。切开粘骨膜达颏骨表面,骨膜剥离子剥离显露颏骨骨面。对于中度小颏畸形,可单纯采用Medpor植入术,对于重度小颏畸形,先通过截骨前移的方法予以矫正,如果仍显不足,可在术后半年,在截骨前移的基础上,再采用Medpor植入,进一步增加颏部的前突度和高度。结果本组共21例,其中女性患者19例,男性2例,年龄17～36岁,平均24岁。单纯采用Medpore假体植入隆颏术12例,颏部截骨前移6例,颏部截骨前移加二期Medpore假体植入隆颏3例。术后小颏畸形明显改善,形态良好。结论对于中重度小颏畸形可采用Medpore假体隆颏、颏部截骨前移或二者结合的手术方法予以矫正。Medpore是一种良好的隆颏材料,其隆颏效果优于传统的硅胶假体。
Objective To study the cosmetic surgical treatment of moderate or severe micrognathia.Methods The chin bone was exposed through intraoral approach. Moderate micrognathia was treated by chin augmentation with Medpore implant.The severe cases were treated by genioplasty,or combined with chin augmentation with Medpore implant.Results From September,2002 to December,2004,21 cases of moderate and severe micrognathia were treated with satisfactory result.Chin augmentation was performed in 12 cases,genioplasty in 6 cases and a combination of both the two procedure in 3 cases.Conclusion Chin augmentation with Medpore implant,genioplasty or combined the both procedures are suitable for the correction of moderate and severe micrognathia.
