Zygomatic maxillary fractures, also known as tripod fractures, are usually the result of a direct blow to the body of the zygoma. Tripod fracture consists of (a) zygomatic arch fracture, (b) fracture of the lateral orbital wall, and (c) fracture of the inferior orbital floor. The purpose of this study is to evaluate the functional and esthetic outcome following this lateral orbital approach in the management of zygoma fracture. This study was carried out in VMS Dental College, Salem, and in a private hospital. This study was based on the experience gained from a retrospective study of the 30 lateral orbital approaches that were used in 30 patients with fractures of the zygomatic complex, which were conducted for a period of 8 years between January 2003 and January 2011. In the retrospective study, all the 30 patients were able to open the mouth completely; eyeball movements were normal; esthetically, all patients appeared normal. There were no sinusitis or visual problems in any of the studied patients. We conclude that the lateral orbital approach is an ideal option in reduction and treatment of zygomatic bone and arch fractures.
