Abstract

BACKGROUND/AIMS: Loss of consciousness while falling is reported to increase the risk of more severe injury. However, few studies of maxillofacial injuries have been reported. The aim of this study was to investigate the effects of loss of consciousness on maxillofacial fractures in falls on a level surface (simple falls). MATERIAL AND METHODS: Patients with maxillofacial fractures caused by simple falls were subdivided into two categories: patients who fell without loss of consciousness, and patients who fell with loss of consciousness, according to the Guidelines for the Diagnosis and Management of Syncope (version 2009). The severity of the injuries was compared between these two groups.

RESULTS: In 413 patients with maxillofacial fractures, 58 cases were falls without loss of consciousness, and 44 cases were falls with loss of consciousness. In falls with loss of consciousness, 54.5% were reflex syncope, followed by syncope due to orthostatic hypotension (15.9%), epilepsy (15.9%), and cardiac syncope (9.1%). The average number of fracture lines in the mandible was significantly lower in falls without loss of consciousness (1.53±0.7) than in falls with loss of consciousness (2.00±1.00) (P=0.045). The average Facial Injury Severity Scale score was lower in falls without loss of consciousness (2.24±1.20) than in falls with loss of consciousness (2.68±1.39). Fractures of other parts of the body were significantly more common in falls without loss of consciousness (22.2%) than in falls with loss of consciousness (9.1%) (P=0.0135).

CONCLUSIONS: Patients with loss of consciousness and maxillofacial fractures due to simple falls showed a tendency to sustain more severe maxillofacial injuries than those without loss of consciousness. This article is protected by copyright. All rights reserved.
