A Hamonização Orofacial e a anatomia orofacial são indissociáveis e são áreas pertinentes na atualidade em Medicina Dentária.
Objetivos: Discutir a importância do envolvimento de músculos da mímica facial perioral (elevador de lábio superior, zigomático maior e menor, músculo mentoniano, orbicular superior do lábio e depressor do ângulo da boca) para a gestão de um sorriso estético, identificando os pontos anatómicos de maior relevância. Comparam-se resultados clínicos com os de autoperceção/ satisfação do paciente, após aplicação de protocolo de toxina botulínica em 4 grupos: a) Sorriso Gengival; b) Mento (Mentonianos e impacto no mento); c) Depressor do ângulo da boca (Depressor do ângulo da boca e impacto nas comissuras labiais); d) Orbicular superior do lábio (Orbicular superior do lábio e impacto no lábio superior).
Materiais e Métodos: Estudo transversal em pacientes (n=30), submetidos à aplicação de toxina botulínica em ambiente clínico. Comparação do antes/depois através de avaliação clínica com base no registo fotográfico. Autopreenchimento pelos pacientes de questionários de qualidade de vida e satisfação FACE-Q.
Resultados: Foi observada uma diminuição da contração muscular estatisticamente significativa nos grupos Sorriso gengival, Mento e Depressor do ângulo da boca. No grupo Orbicular superior do lábio, não foi identificada qualquer alteração.
Foi possível encontrar uma relação entre o resultado clínico e a autopercepção/satisfação do paciente, refletida mediante o resultado reportado nos questionários FACE-Q e em particular nos grupos Sorriso gengival e Mento. No grupo Depressor do ângulo da boca, foi identificada uma alteração clínica, mas não acompanhada pelos resultados de satisfação reportados pelos pacientes. Confirmou-se a segurança documentada na aplicação da toxina botulínica.
Conclusões: A toxina botulínica foi eficaz na diminuição de contração muscular na maioria dos grupos musculares periorais envolvidos no sorriso estético e confirmou-se segura. Os questionários FACE-Q podem constituir uma ferramenta importante para uma melhor compreensão e acompanhamento da expectativa e satisfação do paciente.
Orofacial Harmonization and orofacial anatomy are inseparable and are currently relevant areas in Dental Medicine. Goals: Discuss the importance of involving the perioral facial muscles (levator labii superioris, zygomaticus major and minor, mentalis muscle, orbicularis superioris labrum and depressor anguli oris) for managing an aesthetic smile, identifying the anatomical points of greatest relevance. Clinical results are compared with those of patient self-perception/satisfaction, after application of the botulinum toxin protocol in 4 groups: a) Gummy Smile; b) Mento (Mentonians and impact on the chin); c) Depressor angle of mouth (Depressor angle of mouth and impact on the labial commissures); d) Superior orbicularis labrum (Orbicularis superior labrum and impingement on the upper lip). Methods: Cross-sectional study on patients (n=30) undergoing botulinum toxin application in a clinical environment. Before/after comparison through clinical assessment based on photographic records. Patient self-completion of FACE-Q quality of life and satisfaction questionnaires. Results: A statistically significant decrease in muscle contraction was observed in the Gummy smile, Mento and Depressor anguli oris groups. In the Superior orbicularis labrum group, no changes were identified. It was possible to find a relationship between the clinical result and the patient's selfperception/satisfaction, reflected through the results reported in the FACE-Q questionnaires and in particular in the Gummy smile and Mento groups. In the Depressor of the angle of mouth group, a clinical change was identified, but not accompanied by the satisfaction results reported by patients. The documented safety in the application of botulinum toxin was confirmed. Conclusions: Botulinum toxin was effective in reducing muscle contraction in most perioral muscle groups involved in the aesthetic smile and was confirmed to be safe. FACE-Q questionnaires can be an important tool for better understanding and monitoring patient expectations and satisfaction.
