Nasoethmoid orbital fractures: diagnosis and treatment.

Blunt trauma to the midface frequently results in fractures of the nasoethmoid orbital skeleton. These complex injuries are often misdiagnosed or inadequately treated and are perhaps the most difficult of all facial fractures to treat. The purpose of this article is to describe the author's technique for the diagnosis and treatment of these complex fractures. Presented is an organized approach to the diagnosis and surgical management of nasoethmoid orbital fractures that has evolved in the author's treatment of over 450 nasoethmoid fractures. Early diagnosis is confirmed by computed tomographic scan using the simple classification system described. Fractures that demonstrate displacement or movement on examination require open reduction and stabilization. Identifying the extent and type of fracture pattern and associated injuries determines the exposure and method of fixation needed. Wide exposure with meticulous reduction is necessary, with stabilization of the medial orbital rim fragment using a transnasal wire technique. Plate-and-screw fixation of the superior and inferior rim is performed with bone graft reconstruction of the nose as needed. Attention to redraping of soft tissue in the naso-orbital valley with the use of nasal compression bolsters is a crucial step in the repair. Multiple clinical cases are used to illustrate the different fracture patterns, soft-tissue injuries, and surgical technique recommended. This organized approach has proven effective in restoring preinjury appearance. Early diagnosis combined with the aggressive surgical techniques described will optimize results and minimize the late posttraumatic deformity.
