Therapeutic use of botulinum toxin type A in treatment of crows feet

Fragkos A., Stroe S. Roxana, Ionica M., Voicu A.V.
Abstract: Botulinum toxin is a neurotoxin produced by Clostridium botulinum, a gram-positive, rodshaped, anaerobic bacteria. Human botulism is caused mainly by types A, B, E, F and possibly by G. Types C and D cause toxicity only in animals. Although these toxins have different intracellular targets, their biological activity at the neuromuscular junction is similar. Of these serotypes, only A and B are currently available as commercial preparations. In aesthetic medicine, botulinum toxin is used for treatment of expression lines such as glabelar lines, frown lines and lateral canthal lines or `crows feet`. The authors present five cases of treatment with botulinum toxin in crows feet. Botulinum toxin injections have become usual to combat the effects of aging. As the motto `youth without age` is the motto of each of us, people will always continue to fight with all possible weapons against physiological aging. By knowing the best methods of treatment and side effects, doctors can safely apply this treatment.
