Bursitis: a factor in the differential diagnosis of orofacial neuralgias and myofascial pain dysfunction syndrome

A woman had pain on swallowing and talking when initially seen. Previous diagnoses of glossopharyngeal, neuralgia and myofascial pain dysfunction syndrome had been made. Appropriate treatment for these conditions failed to produce any improvement. Palpation revealed two tender areas bilaterally, overlying the hamulus. Treatment with an injection of 1 ml of dexamethasone (Decadron) 4 mg/ml into each area of tenderness resulted in a dramatic improvement. An anatomic review disclosed the presence of a bursa on the hamulus to protect the tendon of tensor veli palatini. A diagnosis of bursitis was made because of the dramatic improvement in the patient's condition as the result of corticosteroid therapy. Bursitis should therefore be considered in the differential diagnoses of orofacial neuralgias, temporomandibular joint dysfunction, and myofascial pain dysfunction syndrome.
