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

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 acceped 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.
