Maxillofacial injuries in multiply injured patients.

Experience in team management of multiply injured patients with maxillofacial injuries is reported. During 1992, out of 169 patients transferred to the Royal London Hospital, UK by the Helicopter Emergency medical Service 38 (22.4%) had injuries to the maxillofacial region, 17 of whom were scored on the Abbreviated Injury Scale (AIS) as having sustained facial AIS > 2. The median Injury Severity Score (ISS) was 22, while the ISS was 17.7 for survivors and 34.5 for those who died (chi 2 = 7.3, 0.05 < P > 0.02). Facial AIS (median 4) and facial AIS contribution to ISS were found to be poor indicators of severity of injury. Revised Trauma Score (RTS) and percentage probability of survival (Ps%) were found to be useful discriminators of severity of overall injuries. RTS compared between survivors and those who died was 0.05 < P > 0.02 (chi 2), while Ps% was 0.01 < P > 0.001 (chi 2). It was concluded that the severity of maxillofacial injuries, and hence their contribution to total injury assessments, tended to be underscored. We propose that refined facial injury assessment methods be tested.
