Mandibular  fractures have shown a significant  increase in number of cases in a period of the last 27 months in Egypt. This is not only as a result of Egyptian revolution and increased violence but also due to increased motorbike  drivers among younger age groups. This study investigated the incidence, mode of trauma, pattern of mandibular fractures and other associated injuries at Ain Shams University Hospital, Cairo, Egypt. Patients and methods: The medical records and radiographs of 196 patients having mandibular fracture and presented at Plastic and Reconstructive Surgery Department, Ain Shams University Hospital in a period of the last 27 months (from January 2010 to March 2012) were reviewed. These  Patients  were examined  both clinically  and radiologically for mandibular fractures. Patients' age, sex, smoking  status, drug use, helmet use, mode of injury,  site & type of the fracture & other associated injuries were recorded and assessed. Results: Mandibular fractures most commonly occurred in males between 21 to 30 years of age group. The ratio ofmales to females was 12.6:1(174 males & 22females). Mostoffractures were caused  by motorcycle accidents  (n=150;  76.5%)  ofwhich 92.7%  were secondary to motorbike accidents (n=139),followed by occupational falls & traumas (n=33; 16.8%), violent assaults & quarrels (n=13,· 6.6%). Drugs were a contributingfactor at the time of injury in 3 % (n=6) of fractures. The most common site was parasymphysis (n=72; 36.7%)  followed  by body (n=43,· 21.9%), angle (n=34; 17.3%), subcondyle (n=29,·14.8%), symphysis (n=16·, 8.2%) and alveolus (n=2; 1.02%). Associated other injuries (including other maxillofacial traumas &fractures) were seen in 98% (n=192) & 2%presented as  isolated mandibular fractures (n=4). In conclusion, the mandibular fractures occur with high frequency in road traffic accidents (RTA) and interpersonal  violence. Mandibular  fractures are the most common types of facial fractures treated by the plastic surgeons and reflect trauma patterns, political and developmental status  in Egypt during  the last  27 months.  So, it can provide  a guide  for prevention and management.
