Mandible is the lower facial bone that plays an important role in complex function of chewing, deglutition, speech, supports Tongue and forms contour of lower third of Face. Rapid urbanization has resulted in increase in the number of road traffic accidents with fractures of the Facial bones. Mandible is the second most common facial bone to get fractured. Fractures of the Mandible need intervention at the earliest.
AIMTo retrospectively analyse the cause, age and sex incidence, sites of fracture of mandible, combination of fractures, various diagnostic and treatment modalities that were used.
METHOD AND MATERIALSThe study includes 1087 patients with isolated fractures of the mandible treated in the Department of Plastic Surgery at Gandhi Hospital between the years 2005 to 2014. The patterns of the history, clinical examination, diagnostic tests done were assessed. Age, sex, aetiology, method of management were the variables analysed. The statistical analysis was done using SPSS (Statistical Package for Social Sciences 0 Version 15.0 Statistical analysis software). The values are represented in frequencies and percentages.
RESULTS1087 patients with isolated fractures of the mandible were studied. Steep rise in the incidence from 8.98% in 2005 to 18% in 2014 was noted. Males were more frequently involved (92.64%) in comparison to females. The commonly involved age group was between 21-30 years (54.55%). Most of the patients sustained injury due to road traffic accidents (75.9%) of which majority were two wheeler accidents (45.81%). Parasymphysis was fractured in 41.39%. X-rays were used as the diagnostic modality between the years 2004 to 2010. Later digital X-rays and 3D Computerized Tomography have replaced it. Closed reduction was done in 57.22%. Complications (1.1%) in the form of infection and mal-occlusions were noted.
DISCUSSION AND CONCLUSIONSThe commonest aetiology was road traffic accidents and sense of public awareness is to be created about traffic rules and regulations. Males, age group between 21-30 and parasymphysis were commonly involved. Class I occlusion was achieved with closed method of Maxillomandibular fixation in 57.22% and open reduction was done in cases where closed reduction was not possible and they amounted to 42.77%.
