Abstract
Objective: To evaluate the effect of botulinum toxin type A injection on pain in myofascial temporomandibular disorder.
Patients and Methods: Six patients with temporomandibular myofascial pain were treated with injection of botulinum toxin type A into the painful muscles. The effect was evaluated clinically and by questionnaires completed pre- and postinjection.
Results: All patients showed clinical remission of pain symptoms without any adverse effects during the follow-up period (range, 5 to 12 months).
Conclusion: Botulinum toxin type A injection appears to be effective for the treatment of temporomandibular myofascial pain. This pilot study provides the basis for a large-scale prospective study with a longer follow-up to confirm the findings and conclusions.
Key words: Botulinum toxin type A, Myofascial pain syndromes, Temporomandibular joint disorders
