Oral-maxillofacial trauma of a geriatric population in a super-ageing country.

BACKGROUND/AIM: World population has been ageing, and oral-maxillofacial trauma of geriatric population is expected to increase. The aim of this study was to analyse the characteristic features of oral-maxillofacial trauma in the geriatric population. MATERIALS AND METHODS: Data from 127 patients aged 65 years old or older, who were treated for oral-maxillofacial trauma at the Department of Oral and Maxillofacial Surgery, Hirosaki University, from 2000 to 2014, were retrospectively analysed. The data from 292 patients aged 20-64 years were used as a comparison. RESULTS: Oral-maxillofacial trauma in the geriatric population had been increasing over 15-year period. The male to female ratio was 1.05:1 in the older group and 2.3:1 in the younger group. In the older group, 117 patients (92.1%) had one or more underlying systemic diseases, and 16 (12.6%) had suffered injuries in association with acute medical disorders. The most common injuries in the older group were bone fractures (46.5%). The ratio of fractures in the older group was lower than in the younger group (69.2%). Trauma in the older group most frequently occurred because of falls from a standing height or lower (52.0%), and the mandible was the most common site of fracture (74.6%). A conservative form of treatment for maxillofacial fractures was most commonly (86.4%) chosen for the older group, whilst surgical treatment was most commonly in the younger group (55.0%). CONCLUSION: Oral-maxillofacial trauma in the geriatric population shows characteristic features in terms of aetiology, patterns and treatment modalities.
