Facial bone fracture with dental injuries from a 4-WD air bag deployment: A case report in Qatar

摘要

Background: Injuries from air bag deployment have long been documented and studied like orbital blowout fractures, auditory injuries, etc. However, we report here a case of an alveolar process fracture associated with dental injuries and clear history of face-to-air bag impact only, which has rarely been documented and hence important to be reported. Case report: A 25-year old female front-seat passenger was involved in a head-on collision between her large four-wheel drive vehicle and another similar-sized vehicle. She was unrestrained and suffered facial and dental pain after the air bag was deployed. She denied hitting the dashboard or losing her consciousness. On examination, there was mild skin erythema associated with marked tenderness over her left maxilla and left upper jaw. Her upper left medial incisor was missing, while the lateral incisor and adjacent canine seemed to have been pushed upwards and embedded in their respective sockets. No other injury was elicited and she remained vitally stable. X-ray and CT scan imaging confirmed an alveolar bone fracture with upward displacement of the alveolar margin of the maxilla. Loss of medial upper left incisor, and impaction of the adjacent lateral incisor and canine teeth in the soft tissues at the left naso-labial fold, antero-lateral to the left nasolacrimal bones were also noted. Discussion: It is important to report these to be included in the potential range of injuries associated with air bag impact MVC. It will help widen the physicians range of possible injuries while evaluating an air bag impact MVC patient, hence aiding diagnosis and management. It will also help in the ongoing research for further modifying the techniques and types of protective devices currently used in vehicles to help prevent such injuries, as well as further highlighting the use of restraint along with use of such devices.
