Foreign accent syndrome (FAS) is a rare acquired speech disorder in which a patient speaks in his or her native language but with an accent that sounds foreign to a listener. This condition is usually thought to be caused by an anterior dominant hemisphere lesion, and neuropsychological deficits may or may not accompany the condition. In this article, data are presented on a patient who developed FAS immediately following temporomandibular joint surgery and surgical repositioning of the maxilla and mandible. The patient was neurologically and neuropsychologically evaluated 4 months after the onset of the accent, and she was found to have few neurological but multiple neuropsychological deficits. This case is unique in that comprehensive neurological and neuropsychological data are presented for a rare condition that has not been previously documented in the professional literature as occurring after oral surgery.
