Most injection techniques utilizing hyaluronic acid-based soft tissue fillers have predictable outcomes at the location injected. However, the temporal region has been identified to have aesthetic effects beyond the temple.
To identify and quantify the panfacial aesthetic effects of three different temporal injection techniques.
PATIENTS/METHODS: The medical records of nine female and five male Caucasian patients with a mean age of 50.9 ± 11.9 years were retrospectively reviewed for the effects of these techniques: supraperiosteal, interfascial, and subdermal. Panfacial effects were evaluated by the semiquantitative assessment of aesthetic scores for the temple volume, the temporal crest visibility, the lateral orbital rim visibility, the position of the eyebrows, the severity of lateral canthal lines, the midfacial volume, and the contour of the jawline.
The supraperiosteal injection technique had the greatest influence on improving the temporal volume (25.0%), the temporal crest (33.3%), and the lateral orbital rim visibility (31.0%) scales but had no effects in other facial regions. The interfascial injection technique revealed good effects on improving temporal hollowing (23.3%) but had an even greater effect on the crow's feet (26.8%) and on the position of the eyebrow (33.3%). The subdermal injection technique had its greatest effects in the lower face by improving the contour of the jawline (26.8%) followed by the improvement of the lower cheek fullness scale (14.3%).
Future injection algorithms could utilize all three injection techniques together as one multi-layer injection approach with a tailored proportion of each technique based on the aesthetic needs of the patient.
大多数使用透明质酸基软组织填充剂的注射技术在注射部位都有可预测的效果。然而，颞部区域已被确定具有超出颞部的美学效果。
识别并量化三种不同颞部注射技术的全脸美学效果。
患者/方法：回顾性分析9名女性和5名男性白种人患者的病历，这些患者的平均年龄为50.9±11.9岁，分析了这些技术（骨膜上、筋膜间和皮下）的效果。通过对颞部容积、颞嵴可见度、眶外侧缘可见度、眉毛位置、外眦纹严重程度、中面部容积和下颌轮廓的美学评分进行半定量评估来评价全脸效果。
骨膜上注射技术对改善颞部容积（25.0%）、颞嵴（33.3%）和眶外侧缘可见度（31.0%）评分影响最大，但对其他面部区域无影响。筋膜间注射技术对改善颞部凹陷（23.3%）效果良好，但对鱼尾纹（26.8%）和眉毛位置（33.3%）影响更大。皮下注射技术在下半脸效果最佳，改善了下颌轮廓（26.8%），其次是改善下脸颊丰满度评分（14.3%）。
未来的注射方案可以将这三种注射技术结合起来，作为一种多层注射方法，根据患者的美学需求，对每种技术进行量身定制的比例。
