Multidisciplinary approaches for the prevention and management of capsular contracture: a review of clinical, pharmacological, and biomaterial-based strategies

초록

Capsular contracture (CC) is the most frequent complication associated with silicone-based breast implant surgery and often leads to multiple revision surgeries. The implantation of a foreign object triggers the formation of a fibrous capsule around the silicone implant. Over time, excessive and uncontrollable fibrosis leads to capsule thickening and contraction, resulting in severe pain, discomfort, and implant distortion, all hallmarks of CC. Various strategies have been proposed to prevent or mitigate CC. One common strategy is surface modification of the silicone implant by introducing texture. Implant surface coating with antifibrotic and anti-inflammatory drugs is another common strategy to regulate CC. Anti-inflammatory drugs such as leukotriene inhibitor antagonists (LTRAs) and NSAIDs have demonstrated preventive effects against CC. Recently, the omega-3 polyunsaturated fatty acids (omega 3 PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have emerged as promising candidates due to their anti-inflammatory and anti-fibrotic properties. These naturally abundant compounds have shown potential to reduce collagen deposition, thin the fibrotic capsule, and downregulate fibrosis-related inflammatory cytokines. We also discuss the molecular mechanisms by which omega 3 PUFAs exert their effects and compare their advantages over conventional treatments. Overall, this narrative review outlines the current understanding of CC pathophysiology and highlights existing preventive strategies from clinical, pharmacological and biomaterial-based approaches, providing a foundation for future research on the prevention of CC.
