Abstract

Background
Soft tissue fillers are increasingly used to rejuvenate and beautify the body and face. Unknown foreign materials that have not always been proven to be safe for human use have been used for injections in the past. Various commercial injectable materials have since been developed and are used; however, the number of complications has increased as soft tissue fillers have increased in use.
Methods
A retrospective study of 39 patients with facial foreign body complications who underwent surgical treatment between March 2012 and February 2021 was conducted. Patient information was analyzed, and patient satisfaction was evaluated using a questionnaire after surgical treatment. A comparative statistical analysis was undertaken.
Results
Patients who underwent procedures performed by unlicensed practitioners tended to be older at the time of presenting to the hospital (P=0.004). The degree of satisfaction after surgical repair was significantly lower following the direct approach than after the indirect approach using a bypass incision (P=0.044). The degree of satisfaction significantly decreased (P=0.001) as the number of operations the patient received increased.
Conclusions
When treating complications caused by foreign material injections, surgical removal is a more reliable method than treatment with medication or further injections; however, treatment decisions should be made thoughtfully, and many factors must be considered. Patient satisfaction can be improved by reducing the number of operations and making the appropriate corresponding incisions or excisions to treat the full range of symptoms caused by foreign substances and by indirectly using bypass incisions to mitigate post-surgery scars.
