abstract="During the three years March 2001-February 2004, 7200 patients with maxillofacial trauma were seen at Poorsina Hospital, of whom 2160 had 4752 fractures of facial bones, 3089 (65%) mainly mandibular and 1663 (35%) mainly midfacial. Road traffic collisions accounted for the injuries in 6552 of the 7200 patients (91%), falls in 396 patients (5.5%), assault in 208 (2.9%) and sport and other causes in 44 (0.6%). The male (n=6646) to female (n=554) ratio was 12:1. During summer, Iranian weekends (Thursdays-Fridays) and the Iranian new year (begins on 21 March), the incidence was much higher than at other times.",
