Can capsular contracture appear after 25 years?

Capsular contracture is always an early postoperative complication (fortunately a rare one nowadays with modern macrotextured implants), and never happens beyond the 6th month postp.When the implants are aged, after 10, 15 or even 20 years, the immune system and the tissues of the patient begin to destroy the prosthesis, penetrating it and calcifying them, like a mummification. This very slow motion process may take 2 to 4 years to full onset, and then the breast becomes a very hard, rock touch, structure leading to an aching breast. This is NOT a capsular contracture (fibrotic reaction) but a defensive and favorable phenomenon to protect from the free presence of silicone. When this calcification happens the patient is safe from any extracapsular migration of siilcone particles and the removal en bloc is easy. This mummification happens in 90% of late degradations of implants; only unhealthy patients do not defend properly from ruptured implants.

Capsular contracture is the most common longterm situation which requires reapportion.  If your implants are silicone, the capsule needs to be removed with the implant.  

Although most capsular contractures occur within the first 2 years of surgery it is certainly possible to have a capsular contracture at any point after breast augmentation including decades later.
