Digital infarction in a patient with Raynaud's phenomenon associated with treatment with a specific serotonin reuptake inhibitor. A case report

Palatopharyngeal injuries due to impaction of rigid objects held in the mouth are common. Most are essentially innocuous injuries requiring no specific treatment. However, there is the potential for perforation of the pharyngeal wall with the subsequent development of serious infection such as retropharyngeal abscess or mediastinitis. This possibility is more likely to be suspected in the presence of a visible laceration or puncture wound at the site of impact in the mouth or pharynx. We report three cases in which occult pharyngeal perforation occurred without any clinical signs of breech of the pharyngeal wall. In all cases a lateral soft tissue neck X-ray was diagnostic of perforation, showing the presence of retropharyngeal air. We, therefore, advocate the routine performance of soft tissue neck X-rays in all patients who present with a history of falling on a rigid object held in the mouth.
