The relationship between TMD and otologic symptoms such as tinnitus, vertigo and dizziness has been noted for many years. The existence of otologic symptoms in patients with TMD can be explained by the anatomic proximity and embryologic origin of the structures of the ear and the temporomandibular joint, however the pathogenesis of the symptoms is poorly understood. Serveral hypotheses have been proposed. : Eustachian tube hypothesis, the tensor tympani hypothesis, the otomandibular ligament hypothesis, excessive somatic concern hypothesis. Some investigators have reported that palpation of the deep masseter muscle, sternocleidomastoid muscle or clenching can intensify a patient's tinnitus and in that case, TMD therapy would improve their otologic symptoms. Although tinnitus and vertigo are common symptoms in the general population and also increase with increasing age, those are highly significantly associated with TMD compared with control group. This case report describes the possible mechanism and management of otologic symptoms in patient with TMD who has visited our clinic complaining asymmetric tinnitus and dull pain on her left masseter muscle.
