[Degloving injury of the mandible]

A 13-year-old girl presented at an emergency department after she had fallen on her face when she fell from her horse. During physical examination no apparent extraoral injury was visible, such as lacerations, bruises or oedema. However, intraoral examination revealed extensive laceration of soft tissue. The diagnosis was a degloving injury of the mandible, which is very rare. The treatment consisted of debridement, suturing of the mentalis muscle, the approximate closing of the mucosa, accompanied by treatment with broad-spectrum antibiotics. The injury healed well without any residual complaints. This case underlines the importance of intraoral examination during the evaluation of patients with potential facial injury.
