Objective: To explore the mechanism, clinical manifestation and treatment of joint tinnitus. Methods: The clinical data of 2 patients with exercise-induced tinnitus from 1983 to 1996 were retrospectively analyzed. Results: It is rare in clinic to associate with exercise-induced tinnitus. Its mechanism may be that the nerve fibers that dominate the eye-turn in long-term recovery of facial paralysis grow into the muscle fibers of the orbicularis oris muscle, which lead to the wrong growth and dominance of nerves. Typical clinical symptoms of eyelid closure or lip movement, he felt tinnitus. Severed stapes muscle surgery method can be used to eradicate the symptoms. CONCLUSIONS: Surgical procedures for cutting off the effector stapedius are simple and effective treatments.
