A case of pharyngeal injury in a patient with swallowed toothbrush: a case report

Otolaryngologists encounter cases of various foreign bodies in the oral and pharyngeal regions. One commonly found foreign body is a fish bone, ingested in most cases by carelessness or an accident. These foreign materials are removed by endoscopy or through a simple procedure. However, hypopharyngeal damage is rarely caused by a foreign body in the pharynx following the swallowing of a toothbrush.

A 44-year-old Asian male visited the emergency room with chief complaints of intraoral pain and dysphagia that had started on the same day. The patient had paranoid-type schizophrenia that began 10 years ago; he had been hospitalized and was being treated at another clinic, and was transferred to the emergency room by the medical staff after swallowing a toothbrush. We successfully removed a toothbrush located within the pharynx of a patient with a history of a psychologic disorder via surgery and conservative treatment.

The case with this patient, and a rapid diagnosis as well as treatment is imperative. The presence and state of a foreign body must be determined through a careful physical examination and imaging, followed by the immediate removal of the foreign body, all while keeping in mind the possibility of accompanying damage to nearby tissues.
