ABSTRACT
Abstract

Aim:

To evaluate efficacy and safety of Botulinum toxinA for improving esthetics in the facial complex and correlating them to the dosage and side effects through a systematic review.

Methods:

A literature search was performed using PubMed, Medline, Web of Sciences, and Scopus databases. Quality of studies was appraised through the GRADE system. This review follows the 'Preferred reporting items for systematic review and meta-analysis protocols' (PRISMA-P) 2015 statement. Efficacy was analyzed through improvement rate and effect sizes. Graphical comparison of efficacy and ocular adverse effects (adverse effects around the eye) at various anatomical locations was made by calculating the average improvement rate and adverse events.

Results:

Twenty-five studies were included in this systematic review after application of the inclusion criteria. Moderate to severe cases in glabellar, lateral canthal, and forehead regions showed higher improvement rates between 20U to 50U, with an effect lasting up to 120 days. Gender and age seemed to have a direct effect on efficacy. Headaches were the most common adverse effect, followed by injection site bruising; all adverse effects resolved within 3-4 days.

Conclusions:

Treatment with Botulinum toxinA to enhance esthetics of facial complex is efficient and safe at all recommended dosages. Presence of complexing proteins influenced the efficacy of BoNT-A. undesirable muscular adverse effects around the eyes were more predominant when treating the glabellar region. There was no correlation found between the BoNT-A dosage and side effects, however, an increase in dosage did not always lead to an increase in efficacy.
RESUMO
Resumo

Objetivo:

Avaliar a eficácia e segurança da toxina botulínica-A para melhorar a estética no complexo facial e correlacioná-la com a dosagem e os efeitos secundários através de uma revisão sistemática.

Métodos:

Foi realizada uma pesquisa bibliográfica utilizando bases de dados PubMed, Medline, Web of Sciences, e Scopus. A qualidade dos estudos foi avaliada através do sistema GRADE. Esta revisão segue a declaração "Preferred reporting items for systematic review and meta-analysis protocols" (PRISMA-P) 2015. A eficácia foi analisada através da taxa de melhoria e da dimensão dos efeitos.A comparação gráfica da eficácia e dos efeitos adversos oftalmológicos (efeitos adversos em torno do olho) em vários locais anatômicos foi feita através do cálculo da taxa média de melhoria e dos eventos adversos.

Resultados:

Vinte e cinco estudos foram incluídos nesta revisão sistemática após a aplicação dos critérios de inclusão. Casos moderados a graves em regiões glabelares, canais laterais e testa mostraram taxas de melhoria mais elevadas entre 20U a 50U, com um efeito que durou até 120 dias. O sexo e a idade mostraram ter efeito direto na eficácia. As dores de cabeça foram o efeito adverso mais comum, seguido de hematomas no local da injecção; todos os efeitos adversos foram resolvidos em 3-4 dias.

Conclusões:

O tratamento com toxina botulínica-A para melhorar a estética do complexo facial é eficiente e seguro em todas as dosagens recomendadas. A presença de proteínas complexas influenciou a eficácia do BoNT-A. Os efeitos adversos musculares indesejáveis à volta dos olhos foram mais predominantes no tratamento da região glabelar. Não foi encontrada qualquer correlação entre a dosagem de BoNT-A e os efeitos secundários, contudo, um aumento da dosagem nem sempre levou a um aumento da eficácia.
