Are air bubbles that pop when I touch them normal to have on top of my sternum a few days after Breast Augmentation surgery?

This Is perfectly normal and will disappear in the next few weeks. It is from air and fluid (irrigation, local anesthetic, serum, etc) in the pocket which will be naturally absorbed over time.

Thanks for your question. Likely there is just a little air trapped in the pocket. Your body will absorb this. If it becomes more pronounced, you should contact your surgeon. Best of Luck!

Air bubbles are common as the skin probably has not sealed yet, hard to get synmastia under the muscle as there are still lots of attachments along the sternum, may take a few weeks for the skin to settle back down

It is not abnormal, and will go away in time.  It is not an indicator of a developing symmastia.  You should massage the skin over the sternum.... we suggest our patients massage the area for the first 48hr after the surgery if they experience such air bubbles.

It is not unusual to have crackling sound of your skin after breast augmentation. Small amounts of air get underneath the skin produce this sound. This movies all very quickly and it's not dangerous.Earl Stephenson, Jr, MD, DDS,FACS

This is not uncommon after surgery and should resolve in a few days.  If it doesn't and becomes worrisome, contact your surgeon.

Yes. The technical term is called crepitus, and this is just some air that got trapped under your skin from the surgery. This feels & sounds weird, but it is generally not a problem and should resolve in a couple of days.

It is not unusual to feel small pockets of air and or fluid in the space that has been created for your implants. There are small amounts the air they get trapped in the space where the implant is when it is placed into the body this is especially true of silicone implants. Generally speaking this air and fluid will resolve over a period of one to two weeks. I feel is important that you check with your plastic surgeon and let him know what you are experiencing as he may have further suggestions
