Breast augmentation surgery is the type of surgery in which aesthetic surgery achieves the most successful results. Generally, surgeries are technically simple and the results are good. When the brand model and size selection of the prosthesis is done correctly, it will be easy to reach a successful result. The inside of the prosthesis is filled with more fluid dentures. There are no more water-filled prostheses. Round prostheses are classified as high, medium high and flat. Drip prosthesis accommodates 6 different models: long, medium and short models with different heights. Some companies give importance to softness in all models, while others give importance to product safety. Models with a prosthetic wall of polyurethane and no possibility of capsule contracture are often used in replacement surgeries of the prosthesis over 10 years of age.
