botulinum toxin type-A is used in maxillo-facial surgery for treatment of much muscular and glandular pathology, including bruxism, facial paralysis, spasms and saliva hyper secretion. For bruxism and temporomandibular joint dysfunctions, It is beneficial since it relaxes the elevator muscles in order to counteract the dysfunction, thereby protecting the joint and reducing pain. Considerable damage can be caused by an error in prosthetic rehabilitation with consequences often far removed from the mouth cavity, but few patients lose so much weight and have such a complete closure of the mouth opening. BoNTA treatment was effective since it allowed the patient to return to a normal life and also enabled the odontologist to begin work on improving the patientâs occlusion.
The role of BoNTA for the treatment of manducator dysfunction characterised by an intense muscular tension with limited mouth opening following prosthetic rehabilitation. BoNTA was injected into the muscles under electromyographic control. The first post-treatment follow-up consultation was scheduled 15 days later, during which it was noted that the injected muscles had relaxed, pain had clearly diminished and the mouth opening was now 19 mm. The patient was able to eat more easily, although she/he was biting her cheeks. Botulinum Toxin Type-A Treatment for Severe Trismus of Occlusal Origin: Dominique Batifol and BÃ©atrice Harding-Kaba
