    Journal: Aesthetic Plast Surg; 2010 Oct; 34(5):583-6. PubMed ID: 20383497.
    Abstract:
    BACKGROUND: Novel applications and injection sites for Botox are continually evolving. This study aimed to analyze Botox outcomes for various injection sites to differentiate treatments that consistently yield impressive results from those that produce less patient satisfaction. The change in the prevalence of Botox usage for each facial subsite over a 2-year period also was evaluated. METHODS: A retrospective chart review was performed for 60 patients who received Botox injections in a private cosmetic surgery practice. Patients were sampled from 24-month periods 2 years apart. The information collected included dosing and injection intervals and patterns. The outcomes analyzed included the prevalence of injections by subsite and the retention rate. RESULTS: The most frequently injected subsite was the glabellar region. The findings showed an impressive trend toward increasing numbers of patients receiving treatment of the superolateral orbicularis oculi (57-80%) and the depressor anguli oris (10-20%). CONCLUSIONS: Botox injection for facial rejuvenation has an excellent track record for patient satisfaction. The prevalence of treatment for the traditional injection sites was very stable over the measured period. The study findings support the use of Botox in certain more recently described regions such as the superolateral orbicularis oculi and the depressor anguli oris.
