Abstract

Background
Various materials, commonly called fillers, have been developed and are now used for cosmetic and reconstruction purposes. Indiscriminate injections of illegal and unknown substances have various side effects, among which foreign body granulomas are particularly difficult to treat. Surgical resection can be considered for small and well-defined foreign body granulomas, but complete resection is often impossible for wide facial granulomas, and postoperative deformities may occur. Therefore, this study presents cases where foreign bodies were evaluated using imaging studies and removed through minimally invasive procedures depending on their characteristics.
Methods
Thirty-five patients with chronic granulomas after illegal filler injections treated from 2012 to 2019 were enrolled. Clinically, these granulomas were classified into cystic and infiltrating groups according to the imaging study patterns. Patients in the cystic group underwent puncture and drainage, and those in the infiltrating group were first treated with intralesional laser treatment and then suctioned. If the results were insufficient, surgical removal combined with a lifting procedure was performed.
Results
All 35 patients were women, and their average age was 51 years. Surgery was successful in almost all cases, but four cases of insufficient removal and contour deformity were encountered during follow-up. Two patients underwent reoperation and two patients improved naturally.
Conclusions
In this study, we classified the characteristics of granulomas using preoperative imaging studies. Aesthetically favorable results were obtained using puncture and drainage and tumescent suction, along with, if necessary, surgical removal accompanied by a lifting procedure when removing facial foreign body granulomas.
