Patient Satisfaction with AbobotulinumtoxinA for Aesthetic Use in the Upper Face: A Systematic Literature Review and Analysis of the APPEAL Study.

AbobotulinumtoxinA (AboBoNT-A; Dysport; Ipsen, Boulogne-Billancourt, France/Azzalure; Galderma, Lausanne, Switzerland) is a botulinum neurotoxin type A approved for aesthetic use in the treatment of glabellar lines in adult patients under 65 years in Europe, the United States, and other countries. We sought to analyze current literature on patient satisfaction with aboBoNT-A for upper facial aesthetic indications. A systematic review of literature databases (PubMed/MEDLINE, Embase, the Cochrane Library, and Google Scholar) was performed to identify English-language publications reporting on patients with aesthetic indications (including glabellar lines and wrinkles) receiving aboBoNT-A, that assessed patient and/or physician satisfaction with treatment, with no restrictions on comparator studies. Structured data extraction was used to enable inter-study analysis. A analysis was also performed to assess patient satisfaction by sex and age, using results from the noninterventional APPEAL study of patients' satisfaction with aboBoNT-A for treating glabellar lines. Overall, 22 original research papers were identified. Patient satisfaction rates for aboBoNT-A treatment were significantly higher versus placebo from two weeks to between three and five months postinjection. At two to three weeks postinjection, patient satisfaction rates were 52% and 99% across studies. In studies with later time points, patient satisfaction rates were 85 to 87 percent at 5 months and between 25 and 100 percent at 6 months post-injection. Physician satisfaction was also high (97%-100%, across three treatments). No notable differences in patient satisfaction by sex or age were observed in the APPEAL study. High rates of patient satisfaction have been achieved with aboBoNT-A treatment for upper facial aesthetic indications. Despite the current recommended interval of ≥12 weeks, satisfaction with the aesthetic results of aboBoNT-A therapy is still evident up to 6 months post-injection in some patients.
