Polydimethylsiloxane for augmentation of the chin, malar, and nasal bones

Polydimethylsiloxane (PDMS) is used for augmentation of the chin, malar and nasal bones and is available through three different manufacturers. PDMS has been widely accepted by surgeons for bone augmentation because of its variability in hardness, its ability to be easily molded and shaped, and its biological inertness. Wound repair around PDMS implants is achieved through capsule formation. Fibrous capsule formation can be interrupted by infection, immune reaction, implant migration, or extrusion. Recent studies have shown no correlation between silicone implants and connective tissue disease.
