Background: Bicycles constitute a primary means of transportation, particularly within the scope of urban micromobility. However, the use of this mode of transport is associated with the risk of traffic accidents and subsequent maxillofacial trauma. Cyclists are classified as vulnerable road users, among whom the assessment of injury patterns is a significant issue. This study aimed to identify the most common maxillofacial fractures resulting from bicycle-related traffic accidents. Methods: A retrospective analysis was conducted on the medical records of patients treated at the Clinic of Maxillofacial Surgery at the University Clinical Hospital in Poznan, who sustained maxillofacial injuries as a result of bicycle-related accidents between 2019 and 2023. Results: A total of 99 patients met the inclusion criteria. Most of the study population was males (70.7%), with a median age of 38. Accidents most frequently occurred during the summer months and on Fridays and weekends. The most common fracture site was the mandible (40.4%), with double fractures being the predominant type. Additionally, zygomatic-orbital fractures were frequently observed (30.3%). In terms of treatment, surgical intervention was predominant, and the mean duration of hospitalisation was 6 days. Only 5.1% of patients were under the influence of alcohol at the time of the incident. Furthermore, it was found that isolated mandibular fractures occurred more frequently in younger patients, whereas midface fractures of the Le Fort II and III types were more commonly observed in individuals under the influence of alcohol at the time of the event. Moreover, accidents involving alcohol consumption were associated with a higher incidence of concomitant cranio-cerebral injuries. Conclusions: Defining the profile of maxillofacial fractures resulting from bicycle accidents constitutes a clinically relevant issue. Additionally, identifying the main risk factors and developing preventive measures is of critical importance.

Background: Interpersonal violence is one of the most common causes of maxillofacial injuries. These injuries can range from minor soft-tissue injuries to serious, life-threatening conditions. This is particularly important when injuries occur in an exposed and vulnerable area of the body, such as the facial area. This study aimed to analyse the types of maxillofacial injuries, assess a profile of a typical victim of violence and determine the circumstances of the injury. Methods: A retrospective review was performed on the clinical data of patients managed for maxillofacial trauma resulting from interpersonal violence at the Department of Maxillofacial Surgery, University Clinical Hospital, Poznan, spanning the period from 2021 to 2025. Results: The study group included 510 patients, of which 95.41% were males, and the median age in the study group was 34 years. Furthermore, 14.71% of patients were under the influence of alcohol at the time of the violent incident. Most injuries occurred in 2022 (25.88%). Regarding months, June had the highest reported incidents (10.59%), while Saturday was the most injury-prone day (25.10%). The median days of hospitalisation in the study group was five. The mandible was the most frequently affected area. The most common types of fractures were single mandible fractures (30.59%) and double mandible fractures (27.25%). Most injuries were treated surgically (96.67%). In 10.20% of cases, the intervention of other specialists was needed. Conclusions: It is important to effectively prepare medical staff to receive patients with a history of interpersonal violence to diagnose and treat these types of injuries properly.
