Self-inflicted traumatic macroglossia.

Macroglossia is a potentially life-threatening problem. The multiple aetiologies responsible for this condition include cysts, tumours, amyloidosis, angioedema, and infections. Although injuries to the oral cavity are common, self-inflicted traumatic macroglossia is not common. We report a case of a comatose patient with limb contractures and severe trismus who developed entrapment of the tongue with progressive macroglossia and near auto-amputation of the tongue. The importance of early recognition and treatment of tongue entrapment in comatose patients is emphasised since this is a potentially reversible condition.
