作者应用经眼下穹窿切开修复眶缘及眶底骨折获得成功。此法能暴露内、下、外三个眶壁,并可顺利进行骨折的固定和修复。若与上颌窦手术径路合用,可同时处理上颌窦前壁骨折。愈合后局部疤痕轻,外眦切开有利于眼球退缩易暴露术野和减少于术并发症等优点。手术方法:全麻。下直肌缝牵引线。水平剪开眼外眦皮肤约5mm,钝性分离并剪开外眦韧带下臂,沿下穹窿向鼻侧剪开结膜,暴露眶下缘。在眶下缘前面切开骨膜并剥离,牵开骨膜和眼球,即可暴露三个眶壁,检查发现眶 The authors applied the current fornix incision to repair orbital margin and orbital floor fracture success. This method can expose the inner and outer three orbital wall, and the fracture can be successfully fixed and repair. If combined with maxillary sinus surgery pathways, anterior wall fractures of the maxillary sinus can be treated simultaneously. Local scar after healing is light, leprous cut is conducive to eyeball retraction easily exposed surgical field and reduce the advantages of surgical complications. Surgical methods: General anesthesia. Lower rectus muscle traction line. Horizontal cut open the outer skin of about 5 mm, blunt dissection and cut the lower lobe ligament lower arm, cut along the inferior arch to the nasal side of the conjunctiva, exposing the infraorbital margin. In front of the infraorbital margin incision periosteal and peel off, with the periosteum and eye retraction, you can expose the three orbital wall, check the orbital
