Botulinum toxin A for the treatment of lateral periorbital rhytids.

The lateral periorbital area represents one of the earliest and most bothersome facial stigmata of aging. Although traditional techniques have had limited success in treating the static cutaneous component to rhytid formation in this region, they have been largely unsuccessful in addressing the dynamic hyperkinetic lines that are created by the activity of the lateral orbicularis oculi muscle. Botox A injection represents a safe and reproducible technique to selectively denervate muscle activity in this troublesome area. This minimally invasive technique has led to significant improvement of periorbital lines, either when used as a single agent or in combination with other methods (Fig. 3). As more experience is gained with this toxin, as well as other Botox serotypes, continued progress is likely to occur in this area, as well as in other facial regions.
