Uso da tecnologia digital no planejamento da rinomodelação

RESUMO

A rinomodelação é um dos procedimentos mais complexos na harmonização facial, devido à dificuldade de estabilidade dos resultados e ao risco de necrose. O objetivo do artigo foi relatar o caso clínico de rinomodelação com o uso de ácido hialurônico, toxina botulínica e fios de polidioxanona (PDO), realizada com o auxílio do guia prototipado proveniente do planejamento digital. Paciente do sexo feminino, com 28 anos de idade, apresentava queixa de nariz com ptose. Realizou-se avaliação clínica, fotográfica e o planejamento virtual. A primeira etapa do tratamento consistiu no escaneamento facial com o software Bellus 3D. Este arquivo foi importado no software Meshmixer, onde foram realizados o planejamento digital e posterior impressão do guia. A rinomodelação foi realizada, com base no guia prototipado, utilizando ácido hialurônico aplicado na região de columela nasal associado a dois fios de PDO no dorso nasal e 2U de toxina botulínica no músculo depressor do septo nasal. A paciente foi reavaliada após 15 dias e um mês do procedimento, evidenciando um resultado positivo para o objetivo proposto e apresentando satisfação estética com o resultado. Pôde-se concluir que a rinomodelação realizada com ácido hialurônico, fios de PDO e toxina botulínica é uma técnica segura e com boa estabilidade. O uso do guia prototipado favoreceu a previsibilidade do resultado da rinomodelação.

ABSTRACT

Rhinomodeling is one of the most complex procedures in facial harmonization due to the difficulty in stable results and the risk of necrosis. Thus, the aim of the article was to report the clinical case of rhinomodeling using hyaluronic acid, botulinum toxin and polydioxinone (PDO) threads, performed with the help of a prototype guide from digital planning. A 28-year-old female patient complaining of a nose with ptosis. Clinical and photographic evaluation and virtual planning were carried out. The first stage of the treatment consisted of facial scanning with the Bellus 3D software, this file was imported into the Meshmixer software, where the digital planning and subsequent printing of the guide were carried out. Rhinomodeling was performed, based on a prototype guide, using hyaluronic acid applied in the nasal columella region associated with two PDO threads on the nasal dorsum and application of 2U of botulinum toxin in the nasal septum depressor muscle. The patient was re-evaluated 15 days and 1 month after the procedure, showing a positive result for the proposed objective, and presenting aesthetic satisfaction with the result. Thus, it can be concluded that rhinomodeling performed with hyaluronic acid, PDO threads and botulinum toxin is a safe technique with good stability. The use of the prototype guide favored the predictability of the result of the rhinomodeling.

Key words – Hyaluronic acid; Nasal cartilages; Nose; Aging; Computer-aided design.
