移位性颧骨骨折常累及眶底,文献报道其发生率约在46～60％,为防止连接不正,颧骨骨折需要复位。但在手术复位的同时是否探查眶底,对这方面的指征尚有争改。作者收集旧金山市1978年1月到1985年8月间106例颧骨骨折复位手术并眶底探查的病例进行回顾性分析。重审手术发现和放射拍片(包括体层拍片,CT扫描)检查。作者等将病例按病情分成二组。一组包括眶底线样骨折,眶底缺损在10mm以内以及探查阴性者共67例。二组包括眶底粉碎性骨折,缺损在10mm以上,眶底疝
Migration of zygomatic fractures often involving the orbital floor, the literature reported that its incidence of about 46 ~ 60%, in order to prevent the connection is not correct, zygomatic fracture need to be reset. However, surgical resection of the orbital floor at the same time, there is still controversy in this direction. The authors collected from January 1978 to August 1985 in San Francisco from 106 cases of zygomatic fracture reduction surgery and orbital floor exploration cases were retrospectively analyzed. Reconsideration of surgical findings and radiography (including tomography, CT scan) examination. The authors divided the cases into two groups according to their illness. One group included orbital floor fractures, orbital floor defects within 10mm and a total of 67 cases of negative exploration. Two groups include comminuted orbital fracture, defect in more than 10mm, orbital hernia
