下睑缘切口在眶下壁骨折内固定术中的应用

目的:评价下睑缘切口在眶下壁骨折内固定术中的应用价值.方法:在下睑缘睫毛下约2mm处平行于下睑缘作弧形切口,于眼轮匝肌深面与眶隔浅面之间向眶下缘分离,暴露眶下壁骨折部位,解除骨折线内嵌顿软组织,复位后用弧形钛板固定,细线缝合皮肤.结果:103例眶下壁骨折患者骨折愈合良好,无复视和眼球内陷等并发症.89例切口瘢痕平整、隐蔽、无缺陷;5例轻度下睑外翻,9例局部小皱褶.结论:下睑缘切口在眶下壁骨折内固定术中切口隐蔽,操作简便,创伤小,术野清晰,便于复位和固定.

Application of infraorbital incision in internal fixation of orbital floor fracture

PURPOSE: To assess the effect and advantage of infraorbital incision in internal fixation of orbital floor fracture. METHODS: Curved incision was used for operation, which was 2mm below the inferior eyelash, paralleling to the infraorbital rim. Dissection was made between the orbicular muscle and orbital septum to expose the orbital floor fracture and removed the impacted soft tissues; then internal fixation was carried out with curved titanium plate and the wound was closed routinely. RESULTS: 103 cases of orbital floor fracture obtained excellent bone union and no complication such as diplopia and enophthalmos; scars of 89 cases were flat and unconspicuous; 5 cases developed slight ectropion. 9 cases had local slight fold. CONCLUSIONS: Infraorbital incision in internal fixation of orbital floor fracture has some advantages such as unconspucious incision, easy operation, clear operative field, convenient reduction and fixation, and minimal iatrogenic wound.
