Summary
There are several studies that have considered Botulinum toxin A (BoNT-A) injections are
effective in treating symptoms for Temporomandibular Joint (TMJ) disorders. BoNT-A injections
improve the hyper-tonicity of mandibular muscles and its consequent joint load reduction.
Also injections of BoNT-A, for patients with articular disc displacement, resulted in pain
relief and return of the normal movements of the mandible. The main goal of this study is to
test the beneficial impact of BoNT-A injections in the masticatory muscles of patients
submitted to TMJ surgical arthroscopy.
