Superficial Temporal Artery Pseudoaneurysm following Midface Thread-lift

Facial thread-lifting has been popular because of its ease and safety with short down time. However, many physicians perform the procedure in cosmetic clinics, which can result in several complications. This report describes the surgical treatment of iatrogenic superficial temporal artery pseudoaneurysm (STAP) following thread-lifting. A 27-year-old man developed a painless, pulsating soft mass in the pre-auricular region after undergoing a thread-lift in a private cosmetic clinic 3 months before being referred to the authors’ hospital. The mass was diagnosed as a STAP, using magnetic resonance imaging. The pseudoaneurysm was resected completely, and the superficial temporal artery was microsurgically reconstructed. Although there are some surgical procedures for treating STAP, such as surgical resection and embolization, the former is considered the first choice. Physicians should be trained before performing thread-lifting and must know the possibility of an iatrogenic STAP appearing after the procedure and the face and neck anatomy to prevent complications.
