Dear J. Gray:
Thanks for your question. A breast augmentation video can be viewed by clicking "more" below. I have done many breast augmentations and I like to ask each patient how they are doing at each visit. I encourage them to share any concerns and problems, so I think I have heard just about everything that can happen. I have had several patients report noises or feeling odd sensations from their breast implants from traveling to high altitudes or flying.
Most commonly it is a squeak or gurgling sensation when moving the arm across the chest or upwards. Usually, only the patient can hear or feel it, but sometimes I can hear it too. When it does occur, it is more common in the first few months after surgery and often resolves at a year.
I have one patient who continues to have gurgling 4 years after her surgery. I only occurs when at high altitude, and resolves when she returns to the bay area. Other than the minor annoyance, it does not cause her problems, and she is happy with the improvement in her appearance.
The sensation is likely caused by swelling. A small amount of fluid may accumulate around the implant, and cause the implant to vibrate when is slides in its pocket. It is similar to rubbing your finger around a crystal glass. The good news is, it does not seem to cause any long term problems. It also means your capsule remains at least a little bigger than your implant, and that should keep your result softer.
