Top breast implant augmentation complications include capsular contracture, implant rupture, infection, asymmetry, and changes in nipple sensation. Capsular contracture causes hardening around the implant, while rupture can lead to leaks or deflation. To avoid these risks, choose a board-certified plastic surgeon, follow all pre- and post-operative instructions, and attend regular follow-ups. Proper implant selection, sterile surgical technique, and good overall health also play key roles in minimizing complications and ensuring optimal results.
