Clinical Trial 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.


Clinical Trial Description

Study Objective: To investigate the potential performance of incobotulinumtoxin-A (BTXA) in patients submitted to TMJ surgical arthroscopy. Besides the acceptable good outcomes of TMJ arthroscopy, the authors believe that using a single injection of BTXA into the temporalis and masseter muscles could reduce joint loading and pain, improving TMJ arthroscopy results. The proposed explanation for this study: TMJ arthroscopy is a minimal invasive surgical technique for different types of temporomandibular joint (TMJ) internal derangements. Besides the acceptable outcomes of TMJ arthroscopy, the authors believe that adding to this treatment a single injection of BTXA into the temporalis and masseter muscles could reduce joint loading, improving TMJ arthroscopic results. ;
