Abstract

<p>We report a case of Ehlers-Danlos syndrome treated by eminectomy for an articular eminence of the temporomandibular joint. The patient was a 34-year-old woman who was referred to us from the orthopedic department in our hospital for treatment of left condylar dislocation and pain of the left temporomandibular joint. The patient had experienced the symptom every day since junior high school and performed self-reduction each time. Dislocation had occurred two or three times per day after reaching adulthood. Radiographic findings showed flattening of the part of the left articular eminence. MRI findings showed no reduction of the left articular disc at both the closing and opening positions. Eminectomy of the left temporomandibular joint was performed. There has been no recurrence of the dislocation for a year after the eminectomy, and jaw movement remains good.</p>
