Massive orofacial hemorrhage mostly occurs in younger individuals unilaterally and is associated with extensive LeFort fractures. Here we describe a 91-year-old man who sustained a life-threatening hemorrhage of the bilateral internal maxillary artery (IMA) system with a comminuted LeFort I fracture caused by a road traffic accident while he was driving. His injury severity score was high (34), but no severe brain injury was sustained. Transarterial embolization (TAE) was performed to control the intractable hemorrhage. The patient survived and has an acceptable outcome. Although rare, this case may be representative of a trend in maxillofacial injuries in the elderly resulting from worldwide motorization and steady aging of more active populations. Life-threatening hemorrhage of the bilateral IMA system occurs even in LeFort I fractures. Controlling an intractable oronasal hemorrhage with TAE would lead to survival with less severe morbidity, even for the very elderly with no severe brain injuries.
