Hello and thank you for your question. Steroids are not prescribed as a preparation for a rhinoplasty, but they can be useful to reduce swelling and bruising after your procedure. Because of the powerful nature of this medication, it must be administered by your board-certified facial plastic surgeon and is most often given via injection. If you have your surgery performed by a qualified board-certified facial plastic surgeon with ample experience performing rhinoplasties, you should be able to get your desired result without undertaking any pre-treatment regimen. Schedule a full exam with a board-certified facial plastic surgeon for more information. Good luck! - Elbert T. Cheng, MD
