The case of an elderly person with a tongue laceration due to a suicide attempt that was thought to be caused by a sleep disorder is presented. The patient was a 67-year-old woman who was found to be bleeding from her oral cavity by her family and was taken to the emergency department of Ushiku Aiwa General Hospital. The history of the injury was that she had had a sleep disorder for more than 10 years and had been on medication for many years. She also said that her sleep disorder had worsened because she had fractured her coccyx a year earlier, and her activities of daily living were severely restricted due to pain. This was her first suicide attempt. The patient’s general condition at the time of consultation was stable. Her injuries were localized to the tongue only. The wound was sutured with hemostatic suture under local anesthesia. She started oral intake on the third day and was discharged on the tenth day, since her course was unremarkable. After discharge, she was followed up for the wound, and she began going to a psychiatrist. She was started on psychiatric medication, her mental state became stable, and her sleep disorder began to improve. One year after the suicide attempt, there was no relapse of suicidal ideation, and the wound had healed well.
Elderly people may have diminished mental and physical functions, may have various medical conditions, and are prone to suicide-related events. If oral self-harm is observed, it is necessary to manage the wound properly and to closely examine the patient’s background leading to suicidal ideation and then prevent any relapse of that ideation.
