耳鼻咽喉科手术区与眼眶邻近。大多数耳鼻喉科手术医师,除非曾受过特别的眼科训练,对于眼眶及其内容物,无不望而生畏,总担心会损伤眼球、眼肌和视神经。作者积20余年之临床经验,认为这种危险性诚然存在,但只要掌握有关的解剖知识和精湛的操作技术,同时凭借现代放射线学方法的协助,危险性将可大大减少,眼眶探查也并不比其他手术更困难。作者共作过涉及眼眶的手术527例次,包括各种原因的眼球摘除、眶减压术、经眶筛窦切除术、鼻侧切开术、颅-面联合进路手术、鼻外径路额-筛窦切除术、眼眶感染、筛前动脉结扎术及眼眶外伤等。兹分以下几个方面叙述其认识和体会: 眼眶应用解剖眼眶形如一四边形锥体,其底向前、向外并稍偏向下;尖部为视神经孔或眶 Otorhinolaryngology surgery area and the orbit adjacent. Most otolaryngologists, unless having had special eye training, have no fear of the orbit and its contents, with the general fear of damaging the eye, the eye and the optic nerve. The authors have more than 20 years of clinical experience, that this danger exists, but as long as the relevant anatomical knowledge and superb operating skills, while with the help of modern methods of radiology, the risk will be greatly reduced, orbital exploration is not less than Other surgery is more difficult. The authors made a total of 527 operations involving orbital surgery, including various reasons for enucleation, orbital decompression, orbital ethmoidectomy, nasal lateral incision, cranial-facial approach surgery, nasal diameter route - Ethmoid sinus resection, orbital infection, anterior ethmoidal artery ligation and orbital trauma. The following points are described in the following aspects of their understanding and experience: Orbital application of anatomical eyes such as a quadrilateral pyramid, the bottom forward, outward and slightly downward; tip for the optic nerve hole orbital
