After a full recovery, you should feel free to scuba dive and fly with only a few minor considerations. There may be slight expansion or contraction of the breast implant shell with the changes in pressure. With saline-filled implants, a very small number of air bubbles may form in the implant, and you may feel or hear fluid sounds such as gurgling. There is no reason to feel concerned, as it should correct itself within 24 to 48 hours.
