Background: Fractures of zygomatic complex causes disruption in articulation of zygomatico-maxillary complex, zygomatic complex proper and orbitozygomatic complex. The present study was done to evaluate zygomatic bone and zygomatic arch fractures in study population. Materials & Methods: This study was conducted in department of Oral and maxillofacial surgery from 2012 to 2015. All the patients with history of fractures during this period were retrieved from data of department. Patients with zygomatic bone and zygomatic arch fractures were involved in the study. The diagnosis of fracture was based on clinical and radiological criteria. The data collected included the patient’s age and gender, the etiology and the site of the facial fracture, the existence and type of other injuries. Results: Out of total 360 fractures reported to the department, 112 were zygomatic bone fractures and 153 were zygomatic arch fractures. The difference was non- significant (P-0.2). Zygomatic bone fractures were seen in age group 0-10 years (12), 11-20 years (20), 21-30 years (33), 31-40 years (26), 41-50 years (10) and > 50 years (11). Zygomatic arch fractures were seen in age group 0-10 years (3), 11-20 years (32), 21-30 years (40), 31-40 years (34), 41-50 years (24) and > 50 years (20). The difference was significant (P < 0.05). Among various causes main cause in zygomatic bone fracture was road traffic accidents (RTA) (52), assaults (23), sports injury (24), home injuries (6) and work place accidents (7). In case of zygomatic arch fractures causes were road traffic accidents (RTA) (65), assaults (35), sports injury (22), home injuries (19) and work place accidents (12). The difference was significant (P < 0.05). Conclusion: Zygomatic bone and arch are common among facial bone fractures. Various causes are road traffic accidents, sports injury, and work place injury. Strict law should be made to ensure safety devices on road to avoid these injuries.
