Is getting a new air bubble 9 months post op for my breast augmentation normal?

Foreign sensations such as this are common in the immediate post op period. This is less commonly experienced at 9 months post op. If your overall appearance has not changed it is unlikely to be anything significant. That being said, while air is a possibility, it can also be fluid. Late seromas are possible and should be worked up. As always, discuss your concerns with a board certified plastic surgeon (ABPS).Donovan Rosas MD

Hello, thank you for your question and detailed information!
This is a very unusual situation, I think its important to rule out a late seroma (fluid collection), its very difficult to know if the sound and feeling is air or liquid so I suggest you go to your plastic surgeon to have a propper evaluation a tests (ultrasound).
I hope this helps, wish you the best

These noises probably are not because of air bubbles, but may be because of fluid around the implant. In either case, you should be evaluated by your doctor who may choose to get an ultrasound.
