Acquired brain injury patients who present dysphagia associated with temporomandibular joint dysfunction (TMJD) are more common than expected. TMJD is associated with restriction of mouth opening and jaw movements, thereby interfering with the oral phase of the swallowing process. An 18-year-old female with traumatic brain injury mainly complained of dysphagia when first admitted. After nearly one year of conventional dysphagia therapy, the patient could barely eat a minced diet. The videofluoroscopic swallowing study showed that a soft and bite-sized diet was tolerable to the patient, but the restricted mouth opening and mandibular movement imposed a major limitation of the dietary build-up. After examining the imaging studies, the patient was diagnosed with TMJD attributed to muscle lesion and misaligned stomatognathic system. The patient subsequently underwent a stomatognathic alignment and TMJ strengthening exercise program over a span of two weeks, after which the therapeutic effects were evaluated with the craniomandibular index (CMI) and Mann Assessment of Swallowing Ability (MASA) parameters, before and after the exercise program. The results showed improvements in the neck mobility and orofacial movements, and the patient was able to consume soft and bite-sized diet in the clinical setting. Thus, we propose that active exercise to achieve postural correction and TMJ muscle strengthening are effective treatment options for dysphagia associated with TMJD.
