How swollen am I going to be on Revision Rhinoplasty?

Swelling after a nose job is completely normal and is actually expected.
Swelling will be most visible directly after surgery and in the initial
days following the procedure. However, swelling naturally goes down as
recovery progresses. The majority of your swelling should subside within
two weeks. Complete healing usually takes about 6 months to one year,
after which time swelling should be virtually deflated. For a more
accurate time frame on when to expect swelling to calm down, consult
your surgeon(s).

Revision rhinoplasty through an open approach will probably be associated with significant swelling. It may not be much more than you experienced during the first surgery.  Occasionally it is less swelling, because the surgery is not as all encompassing as the first surgery.  Certainly the upper third of your nose should have very little bruising or swelling.

Swelling after revision rhinoplasty is always more than in primary rhinoplasty and it will take more time to resolve. If your nose has thick skin then, it will take even longer to heal than person with thinner skin.

Open rhinoplasty tends to stay swollen for a longer period of time than closed rhinoplasty. When tip work is performed, the tip tends to stay more swollen for the longest period of time. Since you are not breaking the nasal bones the second time around, there'll be minimal swelling and no bruising on the bridge line.

It would be advisable to prepare as though you WILL be. This is a second operation into abnormal tissues and is being done open. If there is NO work being done on the bones, there may be less swelling into the eye and cheek area.

With an open rhinoplasty, your tip will stay swollen for about the same or even a bit longer than the first rhinoplasty.  Overall, you wont be as swollen since the bones won't be moved.  Make sure your surgeon does open and closed rhinos.  If everything is done open, you may want to get a second opinion from a surgeon who does both.  If you can get away with a closed rhinoplasty, the tip swelling will be considerably less.  Best wishes.
