Orbital fractures are high prevalent and result in several complications such as diplopia, muscular entrapment, visual impairment, and enophthalmos. The goal of orbital reconstruction is to restore orbital anatomy, volume, and globe symmetry. This case report aims to describe the use of transantral endoscopy and 3D printed model for treatment of an orbital floor fracture. A 54-year-old woman presented orbital floor fracture with diplopia and extraocular muscle entrapment. The surgical treatment was performed using a standard titanium mesh bended over 3D printed model, and transantral endoscopy to verify fracture extension and implant adaptation. The postoperative evaluation demonstrates correction of diplopia and ocular motility restriction. Computed tomography scan showed reestablishment of the orbital anatomy. The association of transantral endoscopy and 3D printed models is a feasible technique to improve orbital reconstruction.
眼眶骨折非常常见，并会导致多种并发症，如复视、肌肉嵌顿、视力损害和眼球内陷。眼眶重建的目的是恢复眼眶解剖结构、容积和眼球对称性。本病例报告旨在描述经鼻窦内窥镜检查和3D打印模型在眼眶底骨折治疗中的应用。一名54岁女性因眼眶底骨折伴复视和眼外肌嵌顿就诊。手术治疗采用在3D打印模型上弯曲的标准钛网，并通过经鼻窦内窥镜检查来验证骨折范围和植入物适配情况。术后评估显示复视和眼球运动受限得到纠正。计算机断层扫描显示眼眶解剖结构得以重建。经鼻窦内窥镜检查与3D打印模型相结合是一种可行的技术，可改善眼眶重建效果。
