摘要
目的：探讨髁状突肥大的临床特点及手术方法。方法：总结本院１９７０～１９９７年间收治的髁状突肥大５５例，按其是否伴有下颌升支、体部及邻近颅面骨增大将其分为四型，分别施行髁状突切除术、髁状突下升支后缘“Ｌ”形截骨术、下颌升支垂直截骨术等。结果：男性３４例，女性２１例，男女之比为１．７：１；男性好发年龄为２０～３０岁年龄组，女性为３０～４０岁年龄组。主要表现为髁颈增长，并引起面部非对称性畸形。单纯髁状突切除术难以获得较好的功能。结论：Ⅰ、Ⅱ型施行髁突下“Ｌ”形截骨术，Ⅲ、Ⅳ型施行升支垂直截骨及必要的搭配手术可获得良好的外形及功能。
Objective:The article investigated clinical features of condylar hyperplasia and indicated relevant surgical management. Methods: 55 cases of condylar hyperplasia from 1970 to 1997 in stomatological hospital are fell into four categories according to accompanning manifestation, such as hyperplasi of madibular body, ramus, and neighbouring craniofacial bones. The various surgical manner includes condylar excision, ramus vertical osteotomy, and subcondylar ramus “L”-shaped osteotomy, etc. Results: the ratio of male to female is 1.7:1 with 34 men and 21 women. The average age is 29.2. The main clinical appeareance is overlength of condylar crevicle and subsequent asymmetrical deformity of face. Our experience shows that condylar excision can not approve better function of tempormandibular joint. Conclusions: Subcondylar ramus “L”- shaped osteotomy suited for type Ⅰ and Ⅱ. To type Ⅲ and Ⅳ, mandibular ramus vertical osteotomy my plus necessary operation can gain favorable configation of face and function of condylar.
