One of the most common complaints of aging patients is the appearance of crow’s feet lines in the lateral canthal region. Injections of botulinum toxin will smooth out the rhytids and make the skin look younger.
In addition, although published consensus recommendations can guide dosing and injection site placement, expert technical application is critical, as is individualized treatment for each patient, based on an esthetic assessment. This includes an evaluation of the patient’s unique functional anatomy and a frank discussion of the patient’s desires and goals. Only by addressing these considerations can the best possible outcomes be consistently achieved.
The key to successful treatment with botulinum toxin is to minimize possible complications. The aim of this chapter is to review the application technique and the factors responsible for poor results and provide security measures for its prevention. Emphasis will be placed on technique, prevention, and management of adverse events that are essential for effective treatment.
