The decision of whether to place breast implants under or over the pectoral muscle is a personal one and should be discussed with your plastic surgeon. Each of the solutions has benefits and drawbacks. Submuscular (beneath the muscle) implants position can provide a more natural breast shape and seem more natural in contour, especially in patients with less breast tissue. It causes reduced ripples and less exposure of the implant margins, especially in people who are thinner. For bigger implants, under muscle position provides more and better support. However, because of the muscular manipulation they can require a lengthier recovery period. They may make increased discomfort during the first healing phase too. Finally, There's a slightly higher risk of capsular contracture, a condition where the implant becomes hardened. The best option for you will ultimately rely on a number of variables, including your desired result, your body type, and the advice of your surgeon. Generally speaking, body types with thinner chest walls and less breast tissue make better candidates for over-the-muscle breast implants. Since every person is different, the ideal option may vary depending on your intended implant size, skin elasticity, and general body composition. It's critical to speak with a Board Certified plastic surgeon to go over your specific demands and choose the best location for your breast implants. Hope this was helpful!
