Uma troca recente em Cirurgia plástica e reconstrutiva Open global has brought renewed attention to the injection techniques used for hyaluronic acid fillers in the nasolabial fold (NLF) region. The dialogue highlights both innovative approaches and important safety caveats that practitioners should consider.
In a 2020 article, Dr. Gyu Sik Jung introduced a Técnica de injeção multicamada for NLF correction, involving the use of both high and low particle elasticity fillers placed in the supraperiosteal, deep fat, superficial fat, and subdermal layers. Dr. Jung reported improved longevity and aesthetic outcomes in 20 patients with no complications, though he acknowledged a theoretical increase in embolization risk and advised injecting “carefully and slowly” (Jung, 2020).

However, in a response published in June 2022, Dr. Won Lee and Dr. Eun-Jung Yang raised important safety concerns regarding this approach. They emphasized that A artéria facial, uma das maiores artérias faciais, está localizada perto da NLF em mais de 70% dos indivíduos, com 29% atravessando a camada subcutânea - direcionalmente no caminho das profundidades de injeção comuns (Lee & Yang, 2022).
The authors also cautioned against overconfidence in using blunt cannulas, referencing a 2019 study which found that Uma cânula de 27 - bitola pode penetrar nos vasos com força semelhante a uma agulha (Pavicic et al., 2019). They further called for clearer communication of filler properties using standardized rheological metrics rather than subjective terms like “high particle elasticity.”
This academic exchange underscores a key development in aesthetic medicine: the shift toward Ultrassom - Procedimentos Guiados and heightened anatomical awareness to prevent vascular complications such as necrosis or blindness. Dr. Lee and Dr. Yang advocate for the use of Doppler ultrasound when injecting high-risk zones like the NLF (Lee et al., 2021).
A Wellvani apóia a educação contínua na segurança da injeção e enfatiza que o treinamento dos profissionais, o conhecimento da anatomia facial e o uso da tecnologia de imagem apropriada são essenciais para minimizar os riscos associados a preenchimentos dérmicos.
