The orbital fracture refers to the trauma of a blunt force that hits the eye or causes multiple fractures to the face.According to the nature of the fracture,it could be divided into three categories:blowout orbital fracture,compound orbital fracture,and complex orbital facture.According to the fracture site,it may include the following three categories:the inferior orbital wall fracture,the medial orbital wall fracture,and the complex symphysis of the above two fractures,among which the inferior orbital wall fracture is the most common.With the progress and development of medical technology,surgical repair has become the optimal medical treatment for inferior orbital wall fracture.By operating endoscopic surgery,it is superior that the exact site of the orbital fracture could be observed,contributing to the injury evaluation and the surgical planning.This article reviews the related information of the inferior orbital fracture,including its diagnosis,the auxiliary examination,the surgical indication,the nasal endoscopic surgery methods,its advantages and disadvantages as well as characteristics of various repair materials.%眼眶骨折是指外力撞击眼部引起面中部多发骨折的外伤,按骨折性质大致可分为:爆裂性眶壁骨折、复合性眶壁骨折、复杂性眶壁骨折;按部位可分为眶下壁骨折、眶内侧壁骨折、眶下壁和眶内侧壁联合骨折,其中以眶下壁骨折最为常见.随着医学技术的进步与发展,手术修复是目前治疗眶下壁骨折最理想的方法,利用鼻内镜联合传统入路或直接经鼻腔入路手术具有可直视眶壁骨折的部位、直接评估伤情及制定手术方案等优势.本文针对眶下壁骨折的诊断、辅助检查、手术指征、鼻内镜修复眼眶骨折的手术术式、术式的优点和缺点及各种修复材料的特点等内容作一综述.
