The Role of Botulinum Toxin A in Treatment of Temporomandibular Joint Disorders: A Review

In this study, online databases including Scopus, Medline, Ebsco, Cochrane, EMBASE, and Google scholar were searched for the keywords “pterygoid muscle” and “Onabotulinumtoxin A”.Twenty-four articles were eligible to be enrolled in the study. In 4 interventional studies and 20 descriptive studies, BTX-A was used for the treatment of TMDs. The dosage and number of injections were different in each study; however, the injection methods were relatively similar. Regardless of the type, number of injections, and dosage, injection of BTX-A in lateral pterygoid seems effective in reducing the click sound and other TMJ-related muscle disorders such as pain, hyperactivity, and dysfunction.Keywords●Temporomandibular Joint  ●Pterygoid Muscles  ●Botulinum Toxin
