A retrospective study of patients with mandibular fractures treated at a Swedish University Hospital 1999-2008

Abstract

Background:Fracture of the mandible is one of the most common fractures of the maxillofacial skeleton. However, the etiology, gender, and age distribution vary between different regions and countries, and the purpose of this study was to evaluate the current trend of patients with mandibular fractures at the Department of Oral and Maxillofacial Surgery, in Uppsala, Sweden.Aim:The aim of this retrospective study was to analyze patients with mandibular fractures treated in the University Hospital of Uppsala (the county capital of Uppland) Sweden during a 10-year period (1999-2008).Materials and Methods:This study was designed as a retrospective study of patients admitted to the Department of Oral and Maxillofacial Surgery at Uppsala University Hospital, Sweden. The location of fractures was evaluated clinically by the surgeon and on the X-rays. We classified the data according to gender, age, etiology, day of the week, month of the year, fracture site, and method of treatment of the fractures.Results:Records were collected from patient charts from 266 patients. One hundred eighty-seven patients (70%) with mandibular fractures were of male gender, and 132 patients (50%) were aged 16-30 years. Interpersonal violence constituted the most common etiological factor for mandibular fractures (24%), followed by falls (23%). Forty-nine percentages of the patients were treated surgically, and 51% were treated conservatively. There was an increase of the annual incidence of fractures toward the end of the period, even though not statistically significant.Conclusions:Mandibular fractures occurred primarily among younger men between 16- and 30-year-old. Condyle fractures were the most common fracture site and 50% of the patients required surgery. Summer months and weekends were the most common time of mandibular fractures.

A 6-Year Epidemiological Study of Mandibular Fractures in Traumatic Patients in North of Iran: Review of 463 Patients

“…Maxillofacial fractures are among the most common and complex problems in maxillofacial surgery where mandibular bone involvement is more frequent than other facial bones 12 . The mandible is an important part of the face that has a functional role in speaking, chewing, and swallowing 13 . This bone is more prone to fracture due to the position relative to skull, so that the mandibular fracture, especially in the condylar region, plays as a defense mechanism and prevents severe trauma to the upper sensitive areas such as the brain and skull 14 .…”

“…Furthermore, males are more likely to be involved in traffic accidents and altercations 22 , 23 . Other reasons behind this sex pattern could be higher social activity, drug abuse, vehicular driving, industrial work, and sports issues among males 24 , 25 . In the present study males also outnumbered females at a ratio of 7:1.…”

“…5,6 In contrary, another study stated that violence is the most common cause. 7 It has been shown from previous studies that in developing countries the most common cause of maxillofacial fractures was traffic accidents, whereas it was violence in developed countries. The lack traffic regulations accompanied by poor road infrastructure and old vehicles that do not have safety standards affect the incidence of trauma to the maxillofacial in developing countries.…”
