Clinical Application of Stromal Vascular Fraction Gel in Temple Augmentation Using Deep Injection and Shallow Pave Filling.

Abstract

Temporal hollowing is an early sign of aging, and many techniques comprising the injection of fillers into the temporal fossa to correct this hollowing have been described. To assess the safety of a new technique in which stromal vascular fraction gel is used for temporal hollowing. Thirty-three patients with temporal hollowing were corrected with the aforementioned gel using deep injection and shallow pave filling at the Department of Plastic and Reconstructive Surgery, Guangdong Women and Children Hospital, China, between January 2017 and April 2021. This gel was injected into the double plane via a needle and cannula by the same cutaneous access points to prevent severe vascular injury. Improvement was evaluated by self-assessment, the Hollowness Severity Rating Scale (grade range, 0-3; lower grades represent minimal hollowness), and a satisfaction survey. Self-assessment questionnaire (6questions) results were satisfactory; 44temples (67%) demonstrated more than 2grades of magnitude of clinical improvement. Thirty-one patients (94%) were satisfied with their outcomes; the complaint ratio was low. The high satisfaction rate of patients treated using the stromal vascular fraction gel by deep injection and shallow pave filling suggests that this technique is simple, effective, and safe.
