[Injected non-absorbable fillers in large volumes].

[AIM] To present treatment strategy for large volumes of injectable non-absorbable 'shell-less' soft tissue fillers (vaseline, synthol, silicone etc.).

[MATERIAL AND METHODS] The authors present an experience of surgical treatment of 8 patients who underwent injections of medical vaseline (breast augmentation, n=5) and synthol (muscles enlargement, n=3) and review of the current literature devoted to this problem.

[RESULTS] Injection of large amounts (over 50 ml) of non-absorbable fillers into soft tissues is unacceptable and leads to numerous complications. Oil-based 'shell-less' fillers cannot be removed by minimally invasive techniques (puncture, mini-incisions, etc.) due to multiple diffuse lesions in the form of oleogranulomas (cysts of different size) and surrounding widespread inflammation and fibrosis of tissues. Surgery is the only adequate method. However, this approach is followed by scars and often tissue contour deformation. Migration of these fillers to other anatomical areas (from the neck to the lower extremities) significantly complicates the situation, treatment and results. In case of categorical refusal of patients from surgical treatment and no complaints, they should be properly informed about possible consequences and complications and dynamic medical supervision is necessary. Intraoperative ultrasound examination is useful for the control of radical removal of pathological areas. Timely removal of non-absorbable fillers allows to avoid serious complications and to achieve good aesthetic results.
