Abstract

PURPOSE
The aim of this study was to evaluate the ultrasonographic (US) features of complications associated with injectable fillers in the cervicofacial region.
MATERIALS AND METHODS
This retrospective study was approved by our Institutional Review Board. Thirty-nine patients (37 females and 2 males; mean age: 52 years; age range: 26-83 years), both symptomatic (n = 32) and asymptomatic (n = 7), who underwent cosmetic procedures in the cervicofacial area and US, were included.
RESULTS
All of the cases were classified into five types based on major US features, including (the most common feature) diffuse high echogenicity with posterior snow storming (n = 17, 39%). The other types included a hypoechoic nodule with high echoic lines (n = 10, 23%), a round hypoechoic nodule (n = 12, 27%), a heterogeneously echogenic lesion with internal echoic dots (n = 1, 2%) and an ill-defined non-mass-like fatty lesion (n = 4, 9%). The time between cosmetic injection and evaluation was variable (range: 3 weeks-21 years). Usually, the injected material was either unknown or illegal (n = 24). Ten patients underwent pathological evaluation. Many histological types of foreign body granulomas were evident.
CONCLUSION
Knowledge of the US features of complications associated with fillers may reduce the likelihood of misinterpreting the injected area as a true lesion, in turn decreasing unnecessary invasive procedures and costs for patients.
