Characteristics of symphysis and parasymphysis mandibular fractures

ABSTRACT

This descriptive study was conducted to determine the most common site of mandible fractures. 200 patients with fracture mandible who reported to Department of Oral and Maxillofacial Surgery from April 2012 to September 2012 formed study group. Data concerning age, gender, mechanism of injury and site of fracture evaluated and recorded on specially designed proforma. Orthopentomogram [OPG] and where necessary postero- Anterior and right and left lateral oblique views of the mandible were used to diagnose the fracture site. Fracture mandible was predominantly common in males [84%] as compared to females [16%] with male to female ratio of 5.251. The age range was 2-65 years with mean age of 21.45 S.D +/- 12.59 years. The most common age group involved was 21-30 years [30%] and road traffic accident was the common mechanism of injury [57%] followed by fall [31.5%]. Parasymphysis was the most common site when mandible was fractures at a single site i.e., 43%, while parasymphysis and angle fracture combination was observed in 31%. The study revealed that majority of the patients were young adult males. The most common etiological fracture was road traffic accident and isolated parasymphysis was the most common fracture site
