摘要

Introduction The purpose of this manuscript is to investigate the treatment of skin soft tissue embolization or vascular occlusion after the injection of hyaluronic acid (HA) for Injection Rhinoplasty (IR) in Asians with a special interest in the time occurrence of the occlusion. Methods A total of 35 cases were evaluated after receiving HA injections for IR who presented with a vascular occlusive event. They were divided into three stages based on the time to embolization. Immediate, ≤5 hours; early, ≤3 days; and late, >3 days. There were two cases of immediate, 28 deemed early, and five late. Methods to prevent tissue necrosis are reviewed in the manuscript based on these stages. Results Skin color gradually recovered to normal after 11 treatments in 11 patients with mild embolization. No ischemic aggravation or skin necrosis was observed in 19 patients with moderate embolization; red scarring was seen in two and hypertrophic scar with uneven skin color in one patient. The five patients in the severe category had longer healing, more red scars, and more hypertrophic scarring. Conclusion The treatment of skin soft tissue embolization or vascular occlusion after HA IR in Asians can be effected by identifying the stage and degree of embolization and treating appropriately with the outlines presented in this manuscript.
