Genial Tubercle Fracture

Genial tubercle fracture is a rare mandibular fracture. It is classified into 2 different types based on the mechanism of injury, including type I, associated with an atrophied edentulous mandible or denture, and type II, associated with mandibular fracture. Although type I usually can be treated by only observation, type II may cause obstruction of the pharyngeal airway due to hematoma and edema of the floor of the mouth. In this report, genial tubercle fracture associated with mandibular fracture caused by a traffic accident was reported. Reconstructed 3-dimensional images of the pharyngeal airway indicated that there was almost no airway space around the intratracheal tube at the naso- and oropharynx.
