The results of improvement are as follows : Out of 40 patients, overall improvement was found to be 65 %, pain in improvement was 75.7 %, trismus improvement was 76.2 %, articu-larprocess noises improvement was 27.8 %. Myonal was effective for patients with type I (damage in muscle of mastication), and type II (chronic traumato-disease) was significantly more superior than type III (internal derangements) . The side effects were noted tobe 17.5 %, but there was no specifically serious case, and the cause-and-effect relationship with Myonal was unpredictable.
