Mandibular Fractures Epidemiology and Treatment Plans in the Center of Italy: A Retrospective Study

The epidemiology of maxillofacial fractures is variable in different geographic regions. Economic and social conditions, laws and types of behavior can be considered the most important factors influencing these differences. Mandibular fractures were first cited in 1650 BC in an Egyptian papyrus. Today, these fractures are one of the most prevalent facial skeletal injuries. A 4-year retrospective study was performed and the trauma - related data were collected from medical and radiological archives. The analysis comprised patients admitted for mandibular fracture at Sapienza University of Rome - Policlinico Umberto I between January 1, 2016 and December 31, 2019. The data include age, sex, etiology, anatomical sites of the fractures, eventual maxillofacial associated fractures and treatment. We collected 172 patients, 138 males (80.2%) and 34 females (19.8%) with 270 mandibular fractures. The average age was 35.4 years. The youngest and oldest patients were aged 6 and 90 years, respectively. The age group 20 to 29 years was the most represented with 52 patients (30.2% of the total sample). Assaults were the most common etiology (n = 53, 30.8%), followed by falls (n = 45, 26.2%). The condyle was the most involved region (n = 86, 32%), followed by parasymphysis region (n = 72, 26.6%) and angle (n = 62, 23%). 154 patients (89.5%) reported only mandibular fractures. Eighteen patients (10.5%) had other associated maxillofacial fractures; the most frequently encountered maxillofacial fractures associated with mandibular fractures were the zygomatic complex fractures (n = 9, 5.2%). Open reduction and internal fixation was the most preferred surgical treatment (n = 115, 66.9%). This study showed that mandibular fractures predominate in 20 to 29 years group and in the male sex. Assaults are the most frequent cause. The prevalent fracturing site is condylar process. Orbital - maxillary - zygomatic complex fractures were the most common associated maxillofacial fractures and open reduction and internal fixation was the preferred surgical strategy. The results of this analysis agree to other studies and provide important clinical information that will help in study of these injuries.
