Breast augmentation surgery under the muscle, also known as submuscular placement, can have different effects on the appearance of lumpy breasts depending on your specific situation. Here are some factors to consider:1.) Implant Size: The choice of implant size and type will influence the final appearance. Discuss your goals with your surgeon to ensure they can achieve the look you desire.2.) Breast Tissue: If you have naturally lumpy breasts due to fibrocystic changes or other benign conditions, the implants may help smooth out the appearance, but the lumps may still be palpable. Your surgeon can provide more guidance based on your individual case.3.) Implant Placement: Submuscular placement can provide more coverage over the implant, which may help in concealing any irregularities in the breast tissue. However, the final outcome depends on your anatomy and the surgeon's technique.4.) Consultation with Surgeon: It's essential to have a thorough consultation with a board-certified plastic surgeon. They can assess your specific breast anatomy, discuss your goals, and recommend the best approach to achieve your desired results.5.) Realistic Expectations: Keep in mind that breast augmentation can enhance the overall appearance of your breasts, but it may not completely eliminate all pre-existing irregularities.Ultimately, your surgeon will be able to provide you with the most accurate information and recommendations based on your unique circumstances and desired outcome.
