Is Having Rhinoplasty Safe if You're Pregnant?

To quote the legendary tennis star, John McEnroe, "You cannot be serious!" ;-)
Just to add to the universal agreement of my colleagues: do NOT have elective cosmetic surgery while you're pregnant.
If you find a surgeon who's comfortable with the idea of doing a septoplasty or rhinoplasty while you're pregnant, run away as fast as you can. In the meantime, enjoy your pregnancy and best of luck with the delivery,

I'm very glad you asked this question! 
I would strongly advise against undergoing any type of elective surgery procedures while you're pregnant, since there is really no need or reason to put your unborn child at even the slightes risk. I think the best solution for your situation is to wait until after you've given birth or even after you stop breastfeeding, since that's definitely for the best, for both you and the baby!
Good luck! 

As a general rule of thumb, I advise my patients to wait until after their pregnancy to consult a physician and go through with having a nose job. Because the surgery involves anesthesia, it can be unsafe to subject your unborn baby to the stresses and medications that a rhinoplasty procedure requires. A good, informed doctor is aware of this and will refuse to operate on an expecting mother.
