Can I do ovary removal and tummy tuck at the same time? I am 66 years old and in good health

Combining an intra abdominal procedure with a tummy tuck is fine as long as both surgeons are in agreement.  Just make sure you know ahead of time what the added operating room and anesthesia cost will be ahead of time.  Depending on the facility, they may want to charge you a lot for the extra time.  Use your negotiating skills to get a fair price and avoid surprises.

While these surgical procedures have been
performed together, many experienced plastic surgeons feel that this is a bad
combination of surgical procedures to undergo at the same time. There is an
increased risk of bleeding, infection, deep venous thrombosis (DVT)
and subsequent pulmonary embolism with this specific combination. If your plastic surgeon and your gynecologist decide to proceed with this combination, you should have a medical clearance prior to the procedures.Keep in mind that following the advice
from a surgeon on this or any other website who proposes to tell you what to do
based on two dimensional photos without examining you, physically feeling the
tissue, assessing your desired outcome, taking a full medical history, and
discussing the pros and cons of each operative procedure would not be in your
best interest. I would suggest you find a plastic surgeon certified by the
American Board of Plastic Surgery and ideally a member of the American Society
for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable
with. You should discuss your concerns with that surgeon in person.Robert Singer, MD FACSLa Jolla, California

I agree with my colleagues. It can be done at the same time but there are increased risks to doing so. You want to make sure the team of surgeons risk stratify you and assess whether or not this is the right way to go for you. At the end of the day it is all about safety.
