All patients were required to provide written informed consent, which included a photography release form. The study was conducted in accordance with Good Clinical Practices that have their origins in the Declaration of Helsinki. This was a single-center study where data were collected retrospectively using our medical records from March 20, 2015, to June 20, 2017, to identify all patients who were treated at our center for vascular complications associated with facial hyaluronic acid filler injections.

4 We present seven consecutive patients with vascular compromise developing after filler injection, with all, noncoincidently, happened to have a history of rhinoplasty. 4 Unpredictable repositioning of blood vessels and a more tenuous blood supply in the operated nose may increase the risk of ischemia, necrosis, and vascular embolism following the filler injection. Surgical rhinoplasty remains one of the most common procedures performed by plastic surgeons worldwide, with a huge popularity in Asia. 2 Patients often develop severe pain and discoloration in the distribution of the occluded vessels. On the other hand, red or bluish discoloration tends to suggest venous congestion. 1 Blanching or pallor is a cardinal sign that suggests an arterial occlusion. 1 Although most of the complications are transient, there are some irreversible adverse effects that can cause serious functional and aesthetic deficits.įiller injection induced necrosis is a rare but important adverse event that is due to the direct injection of the filler into a vessel. The potential adverse events associated with fillers are injection site reaction, inappropriate placement, product sensitivity, infection, and necrosis. As the number of patients using fillers increases, the number of adverse events associated with injection may increase. Dermal filler injection for face augmentation has gained popularity in the last decades which can be explained by the effectiveness and safety profile of the fillers.
