摘要
Hyaluronic acid (H.A.) filler injections have been associated with early, temporary, and delayed-onset onset complications. High-resolution ultrasound (HRUS) with Doppler analysis has been increasingly used to detect and identify such complications. We describe comprehensively the most common ultrasonographic findings of non-vascular complications associated with H.A. filler injections. This retrospective, cross-sectional observational study was conducted at a reference center for dermatologic ultrasound in Bogotá, Colombia. Ultrasound reports documented the ultrasonographic findings of non-vascular complications of H.A. filler injections. Fifty-two complications were documented in a cohort of 50 patients (women, 88%). The infraorbital region was the most common site affected (23%), followed by the nasolabial (22%). The Tyndall effect was the most common complication (25% of all), followed by changes in rheology (21%) and pseudo-sarcoidal (foreign body granuloma) reaction (15%). The Tyndall effect stood out for its distinctive ultrasonographic characteristics. We discuss the ultrasonographic findings and pathogenesis of other complications, including filler migration, early hypersensitivity, aseptic abscess, overcorrection, and filler material interaction. The clinical presentation of H.A. filler complications can be confusing, delaying timely diagnosis and treatment. HRUS with Doppler analysis is a valuable tool for avoiding unnecessary treatments and ensuring timely diagnosis and treatment.
