Abstract: This is a case of a 63-year-old lady with a history of lung cancer and myotonic dystrophy was referred to the OMFS department. She presented with chronic severe bilateral jaw dislocation, 3.5 months after a video-assisted thoracoscopic lung lobectomy. The patient had lost a considerable amount of weight as she was unable to swallow or eat. Multiple attempts to relocate the jaw were unsuccessful. The patient underwent bilateral eminectomy, bilateral coronoidectomy, release of lateral pterygoid muscles and botox to the submental musculature that did not resolve her symptoms. This lady managed to regain normal range of jaw movement after a bilateral TMJ replacement. Further histopathology analysis showed degenerative changes of the condyles with avascular necrosis.
Early recognition of joint dislocation can prevent permanent damage and the need for complex surgical treatment. This is an unusual case due to the severity of the patient symptoms and the complexity of the treatment.
Summary: Temporomandibular joint (TMJ) dislocation is a known complication that can occur during intubation. If diagnosed early, the joint can often be manually repositioned without complications. We present a complicated case of a TMJ dislocation that went undiagnosed and eventually required bilateral custom-made TMJ replacement.References: 1.
