Other than capsular contracture, what are the reasons an implant doesn't fully drop into it's pocket? I don't have capsular contracture so what other reason would cause this to happen? Doc says I may need to have a pocket revision and trying to decide if it's worth it. I had my implants redone 6 months ago and the left side didn't settle. 225 cc silicone (mentor) to 190 cc silicone (Sientra). Since I went smaller I wouldn't think the the pocket size would be a problem unless it shrunk. ??
