Objectives: The main objective of this lecture is to review the sonographic aspects of different types of filler-related nodules, aiding physicians in selecting the most appropriate treatment. Introduction: Dermal filler injections are generally regarded as safe; however, they may lead to adverse events, one of which is the development of nodules. The inherent characteristics of nodules result in various sonographic features that, when properly interpreted, enable the diagnosis and guide physicians in choosing the most suitable treatment for filler-related nodules. Materials / method: High frequency ultrasound (18-24 MHz) was used to obtain sonographic images of filler and collagen stimulator nodules of patients who came for ultrasound examination in our clinics. The images were compiled and reviewed retrospectively by the authors. Results: Filler-related nodules were subjected to ultrasound scanning and systematically examined. Ultrasound could assist in discerning the nature of various types of nodules, including overcorrection of different types of fillers, superficial filler placement, abscesses, granulomatous reactions, panniculitis and recurrent edema, with the authors documenting them as a series of cases. Conclusion: Ultrasound plays a critical role in providing differential diagnoses of various types of nodules and in assisting injectors in identifying potential complications to ensure effective treatment.
