颞肌筋膜下间隙注射填充材料矫正颞部凹陷的临床安全性及实用性

Clinical practicability and safty of the filler injective plane of posterior temporalis myofascia space for temporal hollows

目的探讨颞肌筋膜下间隙注射填充材料矫正颞部凹陷的安全性、美学效果及实用性。方法选取2014年1月至2016年1月间诊断为颞部凹陷的女性患者，排除颞部既往大手术史、外伤史者。选择颞肌筋膜下间隙作为填充材料（透明质酸或自体脂肪）的注射层次，适度矫正颞部凹陷外观。共收集患者120例，注射透明质酸组52例，随访7．5个月；注射自体脂肪组68例，随访9．5个月，其中6个月后补充注射11例。结果两组颞部外观改善明显，未出现感染、血管栓塞、凹凸不平等并发症，均获得满意的面部年轻化效果。结论颞肌筋膜下间隙是一个潜在的相对密闭、稳定、安全的注射物移植层次，满足了透明质酸或自体脂肪注射填充的安全性和美学需求。但在临床应用中，对整形美容医师的颞部解剖基础要求较高。

Objective To introduce our clinical method of filler injection with the posterior space of temporalis myofascia for temporal hollows, and to discuss the practical practicability, safety and aesthetic outcomes. Methods From Jan. 2014 to Jan. 2016, female patients with temporal hollows who had underwent the filler injecting into the posterior space of temporalis myofascia were involved in our study. The patients with previous history of surgery or trauma on temporal region were excluded. Hyaluronic acid or autologous fat was selected as filler material based on patients＂ preference. Then, aesthetic outcomes were followed up. 120 cases were selected in this study. Among them, 52 cases preferred hyaluronic acid, and the average follow-up time was 7.5 months. 68 cases aeceped autologous fat grafting with average follow-up for 9.5 months. Results All patients got aesthetic and safe outcome. No serious complications were noted, such as infection, embolism, uneven appearance and so on. The satisfactory rate was high in both patients and surgeons. Conclusions The posterior temporalis myofascia space that is relatively closed, stable, lack of vessels has proved to be the safe plane for temporal injection. Not only our injection method could meet the need for injection procedure safety, but also it could ensure the aesthetic outcomes. In clinical practice, the aesthetic surgeons should be well familiar with the temporal anatomy.
