Crow's Feet
When used properly, botulinum toxin can temporarily erase the lateral crow's feet lines. To treat these wrinkles, inject 0.1cc of Myobloc (500 units)-1cm lateral to the lateral canthus. Then inject 0.1 cc of Myobloc (500 units) 1cm above the first injection and 0.1cc of Myobloc (500 units) 1 cm below as shown in the figure.

If the crow's feet wrinkles progress medially, one can inject 0.05cc approximately 1cm apart along the orbital rim to the midpupillary line.
Injecting medial to the midpupillary line does not correct medial wrinkles and can lead to an ectropion; therefore, this area should be avoided.
Most patients do not notice these medial wrinkles prior to Myobloc injections and sometimes mistakenly believe that Myobloc "caused" these previously unobserved wrinkles.
