A retrospective epidemiological analysis of maxillofacial fractures at a tertiary referral hospital in istanbul: a seven-year study of 1,757 patients.

Background: The aim of the study was to evaluate the etiology, incidence, demographics, and characteristics of maxillofacial fractures treated at a university hospital over a seven-year period.

Methods: We performed a retrospective analysis of 1,757 patients with maxillofacial fractures who were referred to our department between May 2012 and March 2019. The patients' demographic and clinical characteristics were noted, as well as the fracture type, location, and etiology. The treatment modalities were also analyzed.

Results: A total of 2,173 maxillofacial fractures were seen in 1,757 patients. The male to female ratio was 3.9:1, and the mean patient age was 31.89 ± 17.70 years (range: 0-95 years). Maxillofacial injuries were most prevalent in the 19-28 years age group (23.9% of cases), with a general increase in injuries observed between 2013 and 2018 across all age groups. The most common etiological factor was assault (29.1%), followed by falls (26%). In male patients, assault was reported as the main cause, while in female patients, falls were identified as the main cause. The nasal bone was the most common site of fracture, followed by the maxilla. The average time from admission to surgery was 2.8 days, with local anesthesia being the most frequent surgical intervention. The average time from admission to surgery was 2.8 ± 2.5 days (range: 0-20 days), with surgeries performed under local anesthesia being more frequent than those carried out under general anesthesia. Among the surgical interventions, the most common general anesthesia technique for fracture reduction was open reduction and internal fixation with plates and screws. Plate exposure, wound-site infection, and temporomandibular joint ankylosis were the major complications encountered in the study population.

Conclusion: The study reveals significant variability in maxillofacial fractures based on gender, age, and etiology. Assault emerged as the leading cause of these fractures, followed by falls and road traffic accidents. Men were affected by maxillofacial trauma four times more often than women, with the highest incidence occurring in the 19-28 years age group. Nasal fractures were the most frequently observed (78.7%), while condylar-subcondylar process fractures were the most common type of mandibular fracture. Given these findings, a targeted, lifelong prevention strategy focused on high-risk groups could significantly reduce the burden of maxillofacial trauma.
