Un recente scambio in Chirurgia plastica e ricostruttiva globale aperta 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 Tecnica di iniezione multistrato 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 L'arteria facciale, una delle più grandi arterie facciali, si trova vicino al NLF in oltre il 70% degli individui, con il 29% che attraversa lo strato sottocutaneo, direttamente nel percorso delle profondità di iniezione comuni (Lee & Yang, 2022).
The authors also cautioned against overconfidence in using blunt cannulas, referencing a 2019 study which found that Una cannula da 27 - calibro può penetrare in vasi con forza simile a un ago (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 Ultrasuoni - procedure guidate 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).
Wellvani supporta l'istruzione in corso nella sicurezza dell'iniezione e sottolinea che la formazione dei professionisti, la conoscenza dell'anatomia facciale e l'uso della tecnologia di imaging appropriata sono essenziali per ridurre al minimo i rischi associati ai riempitivi cutanei.
