The Correlation of Age and Patterns of Maxillofacial Bone Fractures and Severity of Associated Injuries Caused by Motorcycle Accidents.

Abstract

Every year, there are significant numbers of motorcycle accident casualties in Taiwan. These accidents are the leading cause of maxillofacial trauma. Age should be an important factor of maxillofacial fracture patterns yet there is limited literature on the topic. Therefore, this study aims to evaluate the correlation of age with maxillofacial fracture in motorcycle accidents. This is a retrospective descriptive analysis conducted over 2-year period at Linkou Chang Gung Memorial Hospital. We focused on the population of maxillofacial injury caused by motorcycle accidents. Data, including demographics, age, fracture patterns of facial bones, and other associated injuries, were collected. Among 881 admissions, there were 179 patients in the minor group, 644 patients in the adult group, and 58 patients in the geriatric group. With patterns of maxillofacial fracture, midface fracture was the most common type. The minor group had higher incidence of mandibular fracture. The geriatric group sustained more midface fracture. Associated injuries, such as severe head injuries and c-spine injury, were more likely to occur with the old age victims. The overall mortality rate was 3.1%. Our study presents the different trends of fracture patterns in different age groups, which is associated with different types of treatment required. We summarized all these data in the hope of providing further assistance to trauma doctor dealing with motorcycle accidents.
