Effectiveness of electromyography guided botulinum toxin injection and dextrose prolotherapy in recurrent TMJ dislocation (radiographic and clinical study)

Objectives: This study was conducted to assess effectiveness of dextrose prolotherapy, Electromyography (EMG) Guided Botulinum Toxin – A (BTX-A) Injection, and combination between them in treatment recurrent TMJ Dislocation cases. Subjects methods: current carried out on 60 adult patients suffering from Dislocation. The divided equally into three groups, Group I: 20 were treated with EMG guided BTX-A injection. II: prolotherapy. III: injection clinical evaluation preoperatively postoperatively (at 1week , 3 months 6 months) included visual analog scale pain, maximum mouth opening (MMO), frequency luxations . Radiographic using MRI done preoperatively, at months. collected data then statistically analyzed. Results: best results recorded group III compared other groups; all intervals significant reduction pain score, beside improvement MMO measurements. Conclusion: the prolotherapy is a promising dislocation
