Abstract
Dissociative identity disorder (DID) is a psychiatric disorder characterized by the existence of two or more separate and distinct personalities that recurrently control the behavior. We here report a case of a DID patient treated for mandibular fracture.
The patients was a 27 years old female. She has got diagnosis of DID at the age of 24 years and treated and managed with medication. She was injured from a traumatic fall down at home after taking hypnotic drugs and drinking heavily. She was referred to our department for evaluation of trismus and occlusal disturbance. X-ray examination revealed bilateral fractures of the mandibular body. After the consultation with the psychiatrist of our hospital, she was treated with maxillomandibular fixation for 2 weeks under hospitalization for medical care and custody. She was slightly depressed but mentally stable and discharged 3 weeks after admission.
Since DID patients is gradually increasing in Japan, we may encounter such patients for consultation for dental or surgical treatment. It is recommended that these patients should be treated in cooperation with a psychiatrist and if necessary, under hospitalization for medical care and custody.
