breast squeaks and rubs on rib

  The squeaking sound is due to small amount of fluid in the pocket and the movement of the implant.  If the pocket is dissected appropriately, the capsule will form and prevent movement.  The fluid tends to get absorbed as well.

Do not be alarmed. The squeaking is not uncommon, and it always stops.

Your surgeon doesn't seem concerned, because he knows this, but if it is concerning to you, bring it up again so he can reassure you.

Your new implant sliding against the stretched moist tissues causes a friction rub (sound) that can be felt as well as occasionally heard. This is termed "bourdonnement" and was definitively described in the plastic surgery literature: "Bourdonnement and other benign temporary breast implant sounds", Annals of Plastic Surgery, Vol 43 p589, 1999.

The inflammation that causes this sound resolves as the healing process goes forward. It generally goes away in a few days to weeks, but can occasionally take longer, depending on how long your healing process takes. 7 weeks post-op is a bit unusual but not significantly out of the ordinary!

Those of us who still use a stethescope for listening to patients' chests will occasionally hear distinctive sounds such as this that indicate lung/chest (pleural) inflammation that can aid in diagnosis. In your case this sound only indicates that your breast healing is incomplete. You can ask your surgeon if a course of ibuprofen (anti-inflammatory) is OK--this may help your squeak resolve. I have had my own patients describe this even several months after surgery; again, unusual, but not unheard of, so you should not be concerned! Best wishes!
