Midline Volume Filler Injection for Facial Rejuvenation and Contouring in Asians
Aesthetic Plastic Surgery(2019)
摘要
Background 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. Methods 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). Results 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. Conclusions 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.
