Abstract:
BACKGROUND
The occurrence of facial injuries tends to be high compared to injuries in other parts of the body,
because the face is without a protective covering, and the chin mandible is the most prominent bone
in this region of the body. According to several studies, mandibular fractures account for 59% of all
facial fractures. Mandibular fractures usually occur in 2 or more locations because of the bone’s U
shape. This article aims to analyze retrospectively the age, gender, etiology, and anatomic distribution
of mandibular fractures.
METHODS
The data for this study were obtained from the medical records of 1217 cases treated at Department
of Oral and Maxillacial Surgery at National First Central Hospital of Mongolia in 2016. Information was
collected from the clinical notes of each patients with mandible fractures. The demographic variables
such as age, gender and clinical information included diagnosis, etiology, and anatomical distribution
of fractures was assessed.
RESULTS
The total of 229 subjects had mandible fractures, out of which 209 were males and 20 were females.
The mean age of the participants was 32,2±10. The major cause of fractures was assault 79% ,
followed by road traffic accident – 11%, sport injuries – 5%, accidents at work or home – 3%, other –
2%. Mandible fracture incidence were high during in August. By the time referred to a physician from
day of injury were 1-5 days 72,1%, 6-10 days 25,7%, delayed more than 10 days were 2,2% of the
cases. Unilateral fractures were 77,4%, bilateral fractures 21,7%. Mandible left side were 158 (65,9%)
mostly injured. The most common fracture site was angle- 112 (53%), condyle- 58 (27,5%), body- 21
(9,9%), parasymphysis- 16 (7,6%) and at least common site were ramus- 2 (1%) and symphysis - 2 (1%)
of mandible. Among multiple fractures most common sites were condyle-parasymphysis which 24
cases and angle – parasymphysis were 21 cases.
CONCLUSION
The following conclusions have been drawn from the foregoing study.
The mandible fractures were more common in males 209 (91,3%) than females 20 (8.7%). Assaults
were the most common cause of the fracture. 77,4% fractures were unilateral fractures. The most
common site of fracture was mandible angle- 112 (53%) and common multiple fractures were
condyle-parasymphysis. By the time referred to a physician from day of injury were 1-5 days 72,1%,
6-10 days 25,7%, delayed more than 10 days were 2,2% of the cases.
