Classification of crow's feet patterns among Caucasian women: the key to individualizing treatment.

Abstract

One of the most common complaints of aging patients is the appearance of crow's feet lines in the lateral canthal region. Many different treatment methods, including chemical peels, surgical procedures, filler material injections, botulinum toxin injections, and laser resurfacing, have been used for effacement of these lines among aging patients and patients with sun damage. Despite the fact that many scientific articles have been written regarding the treatment of crow's feet lines, the actual patterns of these lines have not been adequately studied or classified. Several different patterns of animation in this area have been observed. These different patterns and their frequencies are described. All crow's feet patterns are not the same, and it follows that treatment of different patterns of crow's feet lines should be adapted to the particular patterns.
