Aims and Objectives:The purpose of the study was to analyze and compare the incidence of road traffic accidents (RTA) with head injuries and maxillofacial injuries in two arterial roads, Old Mahabalipuram road (OMR) and East Coast road (ECR), connecting with Chennai city and outlining the need of safety precautions to be followed to reduce the incidence of morbidity.Materials and Methods:This study involved the medical records of about 1835 trauma victims who reported to Chettinad Health city, kelambakkam, between August 2008 and June 2013. The data analyzed were, age of trauma victims, gender, type of trauma, type of vehicle, accident time, accident zone, presence of head injury, maxillofacial injury and history of alcohol consumption.Results:Trauma victims were predominantly male (84.3%), with majority of individuals in the age group of 21-40 yrs (56%). About 42% of the reported accidents occurred in OMR and 18.3% of accidents occurred in ECR. About 51.2% of the reported road traffic accidents occurred in the busy traffic hours, between 7am-10am and 5pm-9pm. About 66.4% of RTAs were due to two wheeler vehicles and 21.6% were due to four wheeler vehicles. The incidence of head injury was 47.5% and about 1417 (77.2%) patients reported with maxillofacial injuries.Conclusion:RTAs are more common in OMR than in ECR, involving mostly male victims and two wheeler vehicles, during the peak traffic hours. Rash driving and over speeding of vehicles are the preventable causative factors. Wearing of Helmets by the two wheeler riders and seat belts by the four wheeler riders are essential to prevent morbidity. We stress the need of separate lane for Ambulance on the roads for faster transport of accident victims to nearby Hospital and trauma care centers.

Zygomatic bone forms major buttress of the facial skeleton and plays an important role in facial contour. Fractures of zygomatic complex are second most common only next to nasal bone fractures. Motor vehicle accidents and interpersonal violence are common causes. Bilateral fractures of zygomatic complex and zygomatic arch are very rare. We present a case report of isolated fractures involving bilateral zygomatic complex and zygomatic arch with oral submucous fibrosis, which is unique and first of its kind to be reported.

Skull fractures can be classified into four major types; linear, depressed, diastatic, and basilar. Of these, a depressed skull fracture presents a high risk of increased intracranial pressure or hemorrhage to the brain. A compound depressed skull fracture results when a laceration over the fracture exposes the internal cranial cavity to the outside environment. Such depressed skull fractures are indicated for elevation if the defect is more than 10 mm and in the presence of brain injury. Frontal bone contour defects result in marked facial deformity which becomes obvious to the observer. Esthetic correction of the depressed frontal bone fracture can be done with autogenous bone grafts or alloplastic materials. Autogenous bone grafts are meant to be the gold standard method of reconstruction, but they harbor the risk of donor-site morbidity. There are various materials available for the reconstruction of depressed frontal bone fractures. This is a case report which illustrates the use of easily injectable, self-setting calcium phosphate bone cement in the correction of a depressed frontal bone fracture measuring approximately 3 cm × 2.5 cm × 1.5 cm.
