Waiting Period Between Breast Augmentation with Lift and Rhinoplasty?

IF they could be performed simultaneously that would be great. I would probably advise the breast surgery first because if the nose were performed first and then general anesthesis were used soon afterward, the anesthesiologist might apply pressure to your newly reshapened nose. Therefore, my advice would be breasts followed by a wait of a minimum of 3-4 weeks and then the rhinoplasty.

Assuming you're healthy, the recovery from surgery should be relatively quick. With any procedure, though, unexpected events can happen in the postoperative period and you want to ensure you've given yourself adequate time to recover. The metabolic demands of your body increase tremendously after surgery and you do not want to compromise your ability to heal from the second procedure by rushing into surgery. At the minimum, I'd recommend waiting at least 6 weeks between procedures.
If you decide to have rhinoplasty first, be sure to ask your surgeon when he or she would feel comfortable with you undergoing general anesthesia induction. At the beginning of general anesthesia, an oxygen mask is usually placed over your face and nose, and sometimes, significant pressure can be placed on the nose. Your nose should be healed completely prior to potentially traumatizing it in such a manner. If you were my patient, I'd ask you to wait at least 3 months prior to undergoing elective general anesthesia for that reason alone.
Best of luck!

The ideal thing to do would be to have the two surgeons coordinate their schedule if possible to work together and perform your surgery in the same setting.
