Toxina botulínica tipo A
Toxina onabotulinica A
Abstract in Portuguese
A aplicação de toxina botulínica A no lado não paralisado (LNP) é feita para tratar a assimetria resultante da paralisia facial (PF). As unidades de toxina onabotulinica A (Ona) e toxina abobotulinica A (Abo) não são equivalentes. Comparou-se a taxa de conversão de 1:3 em pacientes com PF. Cinquenta e cinco pacientes (idade entre 16 e 67 anos, 43 mulheres), com PF de longa duração foram tratados de forma aleatória com a aplicação de Ona (n = 25) ou Abo (n = 30) no LNP. Efeitos adversos, simetria facial, satisfação subjetiva e Índice de Incapacidade Facial (IIF) foram avaliados após 1 e 6 meses. Os resultados mostraram que a incidência de efeitos adversos foi maior com Abo (93,3% vs. 64,0%, p = 0,007). Avaliação Clínica do LNP diminuiu após 1 mês e aumentou novamente aos 6 meses, sem diferenças entre os grupos. A nota do lado paralisado (LP) foi menor no grupo Ona antes do tratamento, mas semelhante em ambos os grupos depois do tratamento. A nota do LP aumentou depois de 1 mês, e aos 6 meses foi ainda maior que a nota de prétratamento em ambos os grupos. A avaliação subjetiva melhorou em todos os momentos em comparação com a nota do pré-tratamento e diferiu entre os dois grupos apenas em 1 mês, quando o grupo Abo ficou um pouco mais paralisado. Índice de Função Física (IFF) e Índice de Bem-Estar Social (IBES), subescalas do Índice de Incapacidade Facial (IFF), entre os dois grupos não foram diferentes. Concluímos que ambas as toxinas reduziram a assimetria de forma eficiente em pacientes com FP. Os efeitos adversos foram maiores com Abo na equivalência de 1:3

Abstract in English
Botulinum toxin A injection into the nonparalyzed side (NPS) is used to treat asymmetry resulting from facial palsy (FP). OnabotulinumtoxinA (ONA) and abobotulinumtoxinA (ABO) units are not equivalent. We compared the conversion ratio of 1:3 in patients with FP. Fifty-five patients (aged 16-67 years, 43 women) with long-standing FP were randomly treated with either ONA (n = 25) or ABO (n = 30) injections into the NPS. Adverse effects, facial symmetry, subjective satisfaction, and Facial Disability Index (FDI) were assessed after 1 and 6 months. The results showed that the incidence of adverse effects was higher with ABO (93.3% vs. 64.0%, p = 0.007). Clinical scores of the NPS decreased after 1 month and increased again at 6 months, with no betweengroup differences. Scores of the paralyzed side were lower in the ONA group before treatment, but similar in both groups thereafter. The paralyzed side scores increased after 1 month, and at 6 months were still higher than the pretreatment scores in both groups. Subjective assessment improved at all time points compared to pretreatment score and differed between the two groups only at 1 month, when the ABO group was a bit too paralyzed. The Physical Function and Social/Well-Being Function subscales of the FDI did not differ between the two groups. We conclude that both toxins efficiently reduced asymmetry in patients with FP. Adverse effects were higher with ABO at an equivalence ratio of 1:3
