Kinetic energy of a liquid jet has been demonstrated to achieve clinical efficacy by injecting hyaluronic acid for skin thickening and improving facial sagging. A pneumatically accelerated jet penetrates the epidermis leaving HA particles spherically spread in the dermis and initiating microtraumatic wound healing.
We reported retrospective analysis of our successful experience in improving rhytidosis and skin remodeling in the middle and lower facial regions by pneumatically administered HA filler. Subjects seeking correction of facial wrinkles in middle and lower face were treated in 3 monthly sessions with computerized jet-injection device and assessed 6 months thereafter for perception of the wrinkles, rhytidosis burden, and treatment satisfaction.
Thirty-four female patients (average age 42 years) with age-related rhytidosis in perioral, cheek, and neck areas received the treatment. The treatments had short downtime, minimal pain, and no side effects. Mean Lemperle Rating Scale score decreased in all treated areas by one full degree and was maintained for 6 months after the treatments. Patients and investigators independently scored the wrinkles as "improved" per Global Aesthetic Improvement Scale. Mean treatment satisfactory score was 4.0 ± 1.4 (out of 5).
Retrospective data showed successful implementation of liquid jet injections of HA in correction of aging middle and lower facial regions.
通过注射透明质酸来增厚皮肤和改善面部松弛，液体喷射的动能已被证明具有临床疗效。气动加速喷射穿透表皮，使透明质酸颗粒在真皮层呈球形扩散，并启动微创伤伤口愈合。
我们报告了对通过气动注射透明质酸填充剂改善面部中下部皱纹和皮肤重塑的成功经验的回顾性分析。寻求改善面部中下部皱纹的受试者，每三个月使用计算机控制的喷射注射装置进行一次治疗，并在6个月后评估皱纹情况、皱纹负担和治疗满意度。
34名年龄在42岁左右、患有口周、脸颊和颈部与年龄相关皱纹的女性患者接受了治疗。治疗的停工期短、疼痛轻微且无副作用。所有治疗区域的平均莱姆珀尔评分量表分数下降了整整一度，并在治疗后维持6个月。根据全球美学改善量表，患者和研究人员独立将皱纹评为“改善”。平均治疗满意度评分为4.0±1.4（满分5分）。
回顾性数据表明，在改善面部中下部老化区域方面，液体喷射注射透明质酸取得了成功。
