最近の交換 プラスチックおよび再建手術グローバルオープン 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 多層注入技術 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 最大の顔面動脈の1つである顔面動脈は、個人の70％以上のNLFの近くにあります、29％が皮下層を通過しています。これは、一般的な注入深さの経路に直接沿って移動します（Lee＆Yang、2022）。
The authors also cautioned against overconfidence in using blunt cannulas, referencing a 2019 study which found that 27 -ゲージカニューレは、針と同様の力で容器を浸透させることができます (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 超音波-ガイド付き手順 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は、注射の安全性における継続的な教育をサポートし、実務家のトレーニング、顔面解剖学の知識、および適切なイメージング技術の使用が、皮膚フィラーに関連するリスクを最小限に抑えるために不可欠であることを強調しています。
