Hyaluronic acid (HA) injection is popular in cosmetic surgery because of its minimal invasion and immediate recovery. However, few injection techniques are specifically designed for Asians, considering their aesthetic and structural differences from those of Caucasians.
The midline volume injection technique was performed on 37 Asian females and 3 males at sites including the forehead, glabella, nasal dorsum, nasal base and chin. The treatment focused on improving the facial profile projection. 3D image data were collected, and facial aesthetic angles were calculated. Volume changes in facial parts were analyzed before injection and during follow-up. Patient satisfaction was assessed using the visual analog scale (VAS).
The average injected filler volume was 6.14 ± 2.82 ml. The treatment optimized the facial contour and produced instant facial rejuvenation. On 3D images, the average midline volume increased by 6.02 ± 2.23 ml. An average volume decrease of 3.92 ± 1.94 ml was observed in the cheeks and was positively related to the increased midline volume. The average nasolabial and nasal facial angles were increased from 100.00 ± 7.37° to 107.93 ± 9.01° and 28.78 ± 3.28° to 31.78 ± 2.97°, while the mentolabial angle was decreased from 146.55 ± 7.83° to 141.13 ± 6.23°. The mean VAS scores were 2.28 ± 1.27 immediately after injection and 2.56 ± 1.20 after 6 months.
The midline volume injection technique of HA fillers is suitable for Asians. It greatly enhances the facial profile, as illustrated by volume changes in 3D images, leading to a more attractive facial appearance.

透明质酸（HA）注射因其微创和快速恢复而在美容手术中很受欢迎。然而，考虑到亚洲人与白种人在审美和结构上的差异，很少有专门针对亚洲人的注射技术。
对 37 名亚洲女性和 3 名男性进行中线容量注射，注射部位包括额头、眉间、鼻背、鼻基底和下巴。治疗重点是改善面部轮廓的投影。采集 3D 图像数据，计算面部美学角度。分析注射前和随访期间面部各部位的体积变化。采用视觉模拟评分（VAS）评估患者满意度。
平均注射填充物体积为 6.14±2.82ml。治疗优化了面部轮廓，产生了即时的面部年轻化效果。在 3D 图像上，中线体积平均增加 6.02±2.23ml。观察到脸颊的平均体积减少了 3.92±1.94ml，与中线体积的增加呈正相关。鼻唇和鼻面角从 100.00±7.37°增加到 107.93±9.01°和 28.78±3.28°增加到 31.78±2.97°，而颏唇角从 146.55±7.83°减少到 141.13±6.23°。注射后即刻和 6 个月时的平均 VAS 评分分别为 2.28±1.27 和 2.56±1.20。
HA 填充物的中线容量注射技术适合亚洲人。它大大增强了面部轮廓，如 3D 图像上的体积变化所示，使面部外观更具吸引力。
