Buckled upper pole breast style 410 implant presenting as a manifestation of capsular contraction.

Recent experience with the cohesive gel implant has shown an interesting variation of capsular contracture. Instead of spherical contraction, the capsule formation around the 410 implant seems to cause a buckling of the superior pole of the implant. This buckling has been observed in four implants and presented clinically in 2 of 50 patients with a superior pole mass. The capsular contraction around the implant and the buckling are probably camouflaged by a subpectoral implantation and this presentation should be recognized by the surgeon, especially when considering placement of the cohesive gel implant in a subglandular position. Histological sections of a capsule around the implant show fragmented silicone, with a cellular reaction around the fragmented silicone.
