Are the Breasts As Swollen After an Augmentation Revision As They Were the First Time?

It depends on what is being done.  If it is straightforward removal and replacement in the same pocket, the swelling should be less.  If there is a change of pocket, or extensive pocket dissection, then there may be swelling like you remember.  Best to speak with your board certified plastic surgeon.

revision breast surgery may be less painful, assuming the implants are under the muscle, because the muscles have already been stretched.  The amount of pain to expect does depend on what specifically will be done with the surgery.  if it is a simple implant exchange, you should expect very little discomfort.

If there is not a lot of pocket work the recovery ought to be pretty easy.  For example, if I just open an old scar and swap out implants there is little new raw areas and therefore your recovery is easy.

On the other hand, if there is a capsulectomy, a plane change, or other stuff, it may be some recovery. 

So it really depends on the circumstances about YOU.

   Provided that no substantial dissection is done with regard to the pocket or the capsule, the recovery is much easier than the first surgery.  In the simplest of cases, this would involve making the incision, placing the implant, and closing the incision.

As long as the revision does not require significant removal of the scar capsule or change in breast implant pocket (site change), swelling after surgery should be minimal.  Implants being "high" after augmentation is related to implant size, style, location of implant pocket and time required for your tissues to relax and the implants to "settle".  Your appearance following the revision will depend upon each of these factors, as well as what is done surgically to the scar capsules already present.  Since you are having your second augmentation within six months of the first, I would strongly encourage you to be sure to spend enough time discussing your desires with your surgeon, so that the revision meets your goals.

Good luck.
