ABSTRACT
The author reports his experience with the use of botulinum toxin for the treatment of facial wrinkles, facial asymmetry and other pathologies in 509 patients, with a total of 1200 areas applied for a period of 32 months. Botox® was injected into muscles responsible for expression and facial wrinkles. The main zones treated were periorbital, frontal, glabellar and cervical. The toxin was also used aiming at improving facial asymmetry caused by nervous injury, blepharospasm, cervical dystonia, masseteric hypertrophy and axillary hyperhidrosis. Pharmacological aspects are reviewed, as well as the infection technique, dose, complications and results.
