The aim of the present study was to analyze the etiology, type and treatment employed in the orbitozygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

KEY WORDS: zygoma, orbit, facial fractures.
