Aplicação da toxina botulínica como abordagem terapêutica em paciente com paralisia facial periférica: relato de caso

Abstract

Peripheral facial paralysis (PFP) is defined by the partial or total loss of face innervation due to damage in the seventh pair of cranial nerve, the facial nerve. About 80% of patients affected by PFP fully recover, however, some patients have sequelae or develop chronic paralysis. Symptoms are related to the musculature of the face, with involuntary movements, synninesias and hypercontraction. Botulinum toxin type A, widely used clinically, becomes an effective therapeutic alternative in the management of motor disorders by having its mechanism of action in muscle paralysis. With proper planning and management of botulinum toxin, it is possible to strategically modulate the facial muscles of patients with PFP. The present study aims to report the case of a patient with chronic PFP who was submitted to application of TBA. Targeted applications were performed in specific muscle groups, with individualized planning based on detailed clinical evaluation. Before and after the procedure, there were photographic records in several mime movements, in order to compare facial symmetry before and after the action of botulinum toxin in muscle groups. The treatment of PFP using botulinum toxin was seen as beneficial to the patient and with satisfactory results.
