Abstract
BACKGROUND: Facial pain syndromes can be very heterogeneous and need individual diagnosis and treatment. This report describes an interesting case of facial pain associated with eczema and an isolated dyskinesia of the lower facial muscles following dental surgery. Different aspects of the pain, spasms and the eczema will be discussed. CASE PRESENTATION: In this patient, persistent intense pain arose in the lower part of her face following a dental operation. The patient also exhibited dyskinesia of her caudal mimic musculature that was triggered by specific movements. Several attempts at therapy had been unsuccessful. We performed local injections of botulinum toxin type A (BTX-A) into the affected region of the patient's face. Pain relief was immediate following each set of botulinum toxin injections. The follow up time amounts 62 weeks. CONCLUSION: Botulinum toxin type A (BTX-A) can be a safe and effective therapy for certain forms of facial pain syndromes.
