我们于1975年开始使用西北橡胶研究所生产的各种不同类型的医用硅胶制品于临床,其中手塑硅胶块49例,经过较长时间的随访观察,取得较好效果。我们共为额部、颊部、眶底、颏部组织凹陷畸形成形修复22例,鼻部整形13例,腭咽闭合不全14例。成功43例,失败6例,成功率87.7％。现分述如下: 一、额、颊、颏部组织凹陷畸形修复:多采用硅 We started to use various types of medical silicone products produced by Northwestern Rubber Research Institute in 1975, of which 49 cases were hand-molded silicone blocks. After a long period of follow-up observation, we achieved good results. We total for the forehead, buccal, orbital floor, chin repair dent deformity repair 22 cases, nasal plastic surgery in 13 cases, velopharyngeal insufficiency in 14 cases. 43 cases were successful, 6 cases failed, the success rate was 87.7%. Now described as follows: First, the amount of buccal, chin, denture repair: the more use of silicon
