Loud implants at high altitude

Recently I saw a patient that had returned from a 4 day ski vacation in Colorado. She was staying at a resort at about 8000 foot elevation. shortly after arriving she noted strange noises coming from her breast any time she moved. These were quite unflattering and did not stop until she was back home at sea level. She had silicone breast implants for about two years and has had no problems before or since with them. I called several plastic surgery colleagues that practice near ski resorts and none had heard of implants making any noise 2 years after surgery!

Another curious thing. if you have experienced such an occurrence please contact me.
