RESUMO
INTRODUCTION: The epidemiology and treatment of mandibular fracture vary from one country to another. The aim of this study was to present the current demographic pattern and treatment regimens of mandibular fractures in Tunisia. METHODS: The medical records and radiographs of 685 patients treated for mandibular fracture at the Maxillofacial and Plastic Surgery Department in the Tunis Charles-Nicolle Hospital between 1995 and 2004 were retrospectively studied. The relevant parameters were: age, sex, etiology, anatomical site of fracture, and treatment. RESULTS: The prevalence of mandibular fractures was higher in male patients (sex ratio 6:1). Traffic accidents were the main cause of these lesions (45%), followed by assault (22%). Angle fractures were the most common (24.8%) followed by parasymphyseal fractures (22.2%). The most frequent treatment was closed reduction with maxillo mandibular locking in 388 patients (56.6%). Transosseous wiring was the most commonly used method in open reductions. Tooth loss and neurological sensitive deficiency were the most common sequels. DISCUSSION: Our epidemiological data correlates to published data for developing countries. Analyzing this data can help to improve the management of maxillo-facial trauma in Tunisia. Therapeutic options vary according to the type of fracture but also depend on the economical status of the country.
