ABSTRACT

Aim: The aim of the study was to evaluate the efficacy of botulinum toxin type-A therapy (BTX-A: Allergan Inc, USA) in patients with temporomandibular joint disorders (Both intra-articular & extra-articular pathologies) refractory to the conservative management. Materials and method: This prospective, in vivo study was conducted among 11 subjects in the Department of Oral & Maxillofacial Surgery, Maulana Azaad Dental College & Hospital. A clinical proforma was designed along with Numeric Rating Scale (NRS) to record all the pre-operative & post-operative findings in the present study. All non-invasive surgical procedures were performed under aseptic condition by using 5% povidone-iodine solution for skin preparations. Statistical analysis was performed using IBM, SPSS Statistics version 22 (IBM Corp., New York, NY). Results: There was significant improvement in subjective facial pain, inter-incisal distance (mm), decrease in the pain scale and decrease in orofacial dysfunction of masticatory muscles at post 6 months intervention (p<0.05). Conclusion: The injections of BTX-A in masticatory musculatures of TMD patients can be considered as a valuable either first line or second line treatment option refractory to the conservative treatment for controlling complex TMD.
