High-Resolution Ultrasound for Diagnosis and Treatment of Filler-Related Septal Necrosis.

Nonsurgical rhinoplasty using filler injections is a popular procedure; however, it carries risks of significant complications, including vascular occlusion, skin necrosis, blindness, and cerebral ischemia. We present a case of septal necrosis after nonsurgical rhinoplasty and describe management using ultrasound guidance. Awareness of this complication and high clinical index of suspicion are necessary for early diagnosis and treatment, crucial to minimizing permanent sequelae. We show that high-definition ultrasound can help to guide the management and improve the treatment outcomes.
