Facial trauma caused by electronic cigarette explosion.

Electronic cigarettes are increasingly popular as a supposed safer alternative to tobacco cigarettes or a smoking cessation tool. Research and debate have focused primarily on possible adverse effects caused by the inhaled aerosol produced by electronic cigarettes and on smoking cessation efficacy. Few reports in the medical literature describe injuries secondary to device malfunction. We present a case of electronic cigarette explosion, with a projectile fracturing the patient's right naso-orbital-ethmoid complex and anterior and posterior frontal sinus tables, with frontal sinus outflow tract involvement. The patient underwent combined open and endoscopic repair, including open reduction internal fixation, with reconstitution and preservation of the frontal sinus and frontal sinus outflow tract. Additionally, we review the available data on electronic cigarette malfunction-including fires, explosions, associated injuries, and possible reasons for device malfunction-and discuss new 2016 U.S. Food and Drug Administration regulations pertaining to electronic cigarettes.
