Pneumomediastinum, Facial Nerve Injury, and Sialocele Secondary to a Firework Burn to the Cheek: A Case Report.

Fireworks injuries can result in devastating cutaneous burns and may be further complicated in the head and neck region by the presence of specialized deeper structures. In the United States, the head and neck remain the most commonly injured sites, with the majority of these injuries constituting burns. We present an adult patient who suffered an accidental right cheek burn injury and went on to experience a complex pattern of findings including pneumomediastinum, facial nerve palsy, and sialocele formation.
