One of the most common concerns voiced by patients considering breast augmentation surgery is anxiety over selecting the right implant size. If you select an implant that is too small, the improvements gained through the surgery might not be noticeable at all and the time and expense of undergoing the procedure could be wasted. On the other hand, if you select an implant that is too large, the look that is achieved may be unnatural and unattractive. Although plastic surgeons have numerous tools at their disposal to help patients select the proper size of implant, it is often impossible to predict what the ultimate outcome will be until the implant is actually placed. However, with the development of adjustable breast implants, this long-time dilemma might be resolved. Initially developed in the 1980s, today's adjustable breast implants allow for a great deal of flexibility in achieving the desired breast volume. Although the number of times that the volume can be changed is limited and the procedure must be performed at the doctor's office (e.g., you cannot dial up your cleavage at home before a night out on the town), the flexibility afforded by this product represents a significant step forward in breast augmentation.
