전남대학교 응급의료센터에 내원한 구강악안면 외상환자의 외상형태 분석 Retrospective Study of Oral and Maxillofacial Injured Patients in the Emergency Medical Center of Chonnam National University Hospital
pp.735-743
The maxillofacial region is susceptible to damage because facial bone is prominent. The aim of this study is to evaluate the incidence, etiology, seasonal distribution, and patterns of maxillofacial injuries and investigate the percentage of bone fractures on CT scans by patient’s gender and age. Electronic medical records of 1,483 patients who had maxillofacial injuries and visited the Emergency Medical Center of Chonnam National Hospital were evaluated. Age, gender, etiology, seasonal occurrence, frequency of fracture, and the pattern of bone fracture were analyzed by using IBM SPSS Statistics 21 (SPSS Inc., Chicago, IL, USA). Male to female ratio was 2.82:1. The most common causes of injury were falls or collisions (male 40.09%, female 48.2%), followed by traffic accidents and violence. The number of injuries related to sporting accidents, assult, and industrial accidents was higher in male patients than that of female patients. With regard to the seasonal occurrence, 434 cases (29.26%) occurred in the summer, while 306 cases (20.63%) occurred in the winter. In this study, 946 patients (63.79%) were identified to have facture and 537 patients (36.21%) were found to be without fracture on CT scans. The orbital bone (41.38%) was the most commonly fractured in the mid facial structures. The most common fracture site in the mandible was the body of the mandible (23.13%). The patterns of maxillofacial injuries were various based on gender, age, cause of injury, and season.
