Forehead flatness is common in Korean populations, and one of the most straightforward techniques for adding volume and achieving a concave forehead is injecting hyaluronic acid (HA) filler. However, definitive guidelines for this procedure are lacking, and careful attention to the arterial anatomy is required to avoid vascular complications.
The authors aimed to establish guidelines for performing forehead augmentation using Doppler ultrasound to identify vasculature before HA injection.
Arterial mapping of the faces of 34 patients was performed using Doppler ultrasound. Each anatomic layer (skin, subcutaneous fat, and galea aponeurotica) of the forehead with blood vessels was identified. An average volume of 2.85 mL of HA filler was injected. Postoperative complications, such as infection, hematoma, bruising, nodules, skin necrosis, and blindness, were evaluated.
Using Doppler ultrasound, the authors successfully traced all 3 blood vessels (supraorbital, supratrochlear, and frontal branch of the superficial temporal arteries) and avoided them during HA injection. None of the patients experienced arterial complications.
Doppler ultrasound proves to be an effective technique for arterial mapping, enabling the identification and avoidance of the major blood vessels of the forehead before HA filler injection.
额头扁平在韩国人群中很常见，为了增加额头的立体感并使其呈现出凹陷效果，最直接的方法之一是注射透明质酸（HA）填充物。然而，目前缺乏针对这种操作的明确指南，因此需要仔细注意动脉解剖结构，以避免发生血管并发症。
作者旨在制定使用多普勒超声在 HA 注射前识别血管的额部填充指南。
使用多普勒超声对 34 名患者的面部进行动脉图谱绘制。确定了额部带有血管的每个解剖层（皮肤、皮下脂肪和帽状腱膜）。平均注射 2.85 毫升 HA 填充物。评估了术后并发症，如感染、血肿、瘀伤、结节、皮肤坏死和失明。
作者成功地通过多普勒超声追踪到了所有 3 条血管（眶上动脉、滑车上动脉和颞浅动脉的额支），并在 HA 注射时避开了这些血管。没有患者发生动脉并发症。
多普勒超声被证明是一种有效的动脉图谱绘制技术，可在 HA 填充物注射前识别和避开额部的主要血管。
