ObjectivesThe aim of this study was to evaluate the distribution, etiology and type of mandibular fractures in subjects referred to our institution.MethodsA retrospective study of 689 subjects, during the period from May 2010 to September 2013 with mandibular fractures was conducted. Information on age, gender, mechanism of injury and sites of trauma was obtained from the trauma registry. Data were tabulated and analyzed statistically.ResultsA total of 653 subjects had mandibular fractures, out of which 574 were males. The mean age of the participants was 31.54 ± 13.07. The majority of the subjects were between 21-40 years of age, in both males (61.7%) and females (54.4%). The major cause of fractures was road traffic accidents (87.4%) followed by fall (6.9%) and assault (4%), with the least frequent being gunshot injuries (0.3%). Almost half of the patients had parasymphysis fractures (50.2%), followed by angle (24.3%), condyle (20.4%), ramus (2.3%) and coronoid (2%). A total of 115 patients had bilateral fractures out of which 29 had parasymphysis, 12 had body fractures and 74 had bilateral condylar fractures. Double mandibular fractures were reported in 193 subjects; out of which 151 subjects had double contralateral and 42 had double unilateral fractures. Triple unilateral fracture was reported in only one subject. A total of 338 subjects had multiple fractures among the study population.ConclusionsMandibular fractures can be complicated and demanding, and have a compelling impact on patients’ quality of life. Our study reported that parasymphysis was the most common region involved in mandible fractures.

Although tuberculosis can affect any part of the body involving both soft and hard structures with variable measures; such an occurrence in the cranio-facial bones is relatively rare. Once affecting a bone it is rare for a mycobacterial infection to get directed towards the skin and present as multiple draining sinuses. We report a case of tubercular osteomyelitis of the left body of the mandible in a 19 year old male patient who came to us with complains of persisting pus discharge from multiple sinuses on his face (lateral border of mandible and submandibular region) because of its rarity and clinical interest. One should always have a suspicion of mycobacterial infection in the back of mind when dealing with chronic maxillofacial infections not responding to the usual antibiotic course and local debridement.

Clindamycin alone and combination of Penicillin with Metronidazole are both effective pharmaceutical regimens for SOI. Clindamycin therapy resulted in shorter hospital stay and lower net treatment costs with a slightly higher success rate.
