Summary
Polymethylmethacrylate (PMMA) injections can cause severe acute and chronic complications. Histological analysis reveals capsular contracture around PMMA microspheres, leading to tissue hardening and potential extrusion.
Area of Science:
- Plastic Surgery
- Dermatology
- Histopathology
Background:
- Polymethylmethacrylate (PMMA) is used for body contouring and filling depressions.
- PMMA injections are associated with significant acute and chronic clinical compilations.
- This study investigates the link between PMMA use and the physiopathology of its complications.
Purpose of the Study:
- To correlate the clinical application of PMMA with the physiopathology of acute and late complications.
- To analyze histological findings in patients experiencing side effects from PMMA injections.
Main Methods:
- Histological examination of biopsy samples from patients with PMMA-related complications.
- Samples were obtained from individuals who received PMMA injections at external facilities.
Main Results:
- Histological findings showed tissue encapsulation of individual PMMA microspheres.
- Concentric capsular groups formed around multiple PMMA microspheres.
- These capsules were observed in patients with clinical complications and side effects.
Conclusions:
- PMMA injections can lead to severe acute and chronic complications.
- Acute complications involve vascular compromise.
- Late-phase complications result from capsular contracture around PMMA particles, causing hardening, nodulation, and potential extrusion.
