An improved method of removing polyurethane foam-covered gel prostheses

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Medical Device Technology

Background:

• Polyurethane foam-covered prostheses offer advantages over traditional "slick" prostheses, including reduced capsular contraction and improved aesthetic outcomes.
• These prostheses promote tissue fixation, leading to more natural appearance and movement synchronized with surrounding musculature.
• The thicker capsule formed around foam prostheses may also provide protection against gel granuloma, a complication of prosthesis rupture.

Purpose of the Study:

• To introduce and evaluate a novel technique for the removal of polyurethane foam-covered prostheses.
• To address the significant disadvantage of difficult removal associated with these devices.

Main Methods:

• The study describes a new surgical technique specifically designed for the extraction of polyurethane foam-covered prostheses.
• Comparative analysis of removal difficulty was implicitly considered against historical data of "slick" prostheses and previous foam prosthesis removal challenges.

Main Results:

• The newly introduced technique significantly simplifies the removal of polyurethane foam-covered prostheses.
• This advancement overcomes the primary limitation previously associated with these devices, which was their extreme difficulty of removal.

Conclusions:

• The development of an effective removal technique enhances the overall utility and patient safety profile of polyurethane foam-covered prostheses.
• This innovation is expected to improve patient outcomes and surgeon experience by mitigating the challenges of explantation.
