The term pattern in this study was used for the sites/processes of zygomatic bone fracture. The variables evaluated were age, gender, sites of fracture and treatment options. A total of 81 patients with zygomatic bone fracture were treated in Oral and Maxillofacial Surgery unit, Khyber College of Dentistry, Peshawar for a period of one year from July 2007 to June 2008. Majority of patients were young males in 3rd and 4th decade. Male to female ratio was 12.5:1. Road traffic accidents (76.5%) were the most common and interpersonal violence 2.5% as the least common etiology of zygomatic bone fracture. In 28.4% patients, zygomatic bone was fractured at single site while in 71.6% it was fractured at more than one. Fracture at zygomatic buttress and infraorbital rim (27.2%) in combination was most common finding. Twenty three percent patients did not require treatment, 32.1% zygomatic bone fractures were reduced indirectly and 44.4% were reduced directly by open reduction and internal fixation.
