Middle ear muscles have a common embryological and functional origin with masticatory and facial muscles. Therefore, symptoms referred to the ear may originate from the stomatognathic area. When a primary otological cause is discarded in the diagnostic work up for tinnitus, vertigo, hypoacousia, hyperacousia, ear pain or sensation of occluded ear, a temporomandibular joint dysfunction may be the cause of these symptoms.
