What steps can I take to prepare for rhinoplasty to improve healing time?

Thank you for your question. I would advise proper rest, be in good health, no smoking of drinking 3 weeks before surgery. 

In order to increase your chances of healing quickly after surgery, I recommend you avoid smoking or any other tobacco products for a minimum of 1 month before and 1 month after surgery.  Additionally, be sure to eat a well balanced diet with lots of fruits and veggies, meats, and healthy fats.  Try to minimize inflammatory foods such as grains, dairy, sugars and alcohol.  Some people also find that arnica is helpful along with papain and bromelain extract. 

Ask your plastic surgeon for his/her pre and post operative guidelines and follow them.STOP SMOKING: Smoking reduces circulation to the skin and impedes
healing. It is best to avoid smoking, second hand smoke and cigarette
replacements, such as nicotine patches or gum, in the perioperative
period. While you should ideally stop smoking for 2 weeks before and
after your surgical procedure, YOU MUST NOT SMOKE FOR A MINIMUM OF 24
HOURS BEFORE AND 24 HOURS AFTER SURGERY.TAKE MULTIVITAMINS: Start taking multivitamins twice daily to improve your general health once you have scheduled your surgery.TAKE VITAMIN C: Start taking 500 mg of Vitamin C twice daily to promote healing.START TAKING AN IRON SUPPLEMENT: A good iron supplement, such as
Feosol, is required starting one week before surgery and four weeks
following surgery. Bowel movements may appear darker than usual as a
result. Feosol is available without prescription.DO NOT TAKE ASPIRIN OR IBUPROFEN: Stop taking medications containing
aspirin or ibuprofen. Review the list of drugs containing aspirin and
ibuprofen carefully. Such drugs can cause bleeding problems during and
after surgery. Instead, use medications containing acetaminophen (such
as Tylenol).LIMIT VITAMIN E: Limit your intake of Vitamin E to less than 400 mg per day.Procure your prescriptions prior to your surgery.  Arnica and Bromelain have been suggested to reduce postoperative bruising.  Arnica pills are fine, but I am not sure how helpful they
are. The bruising that is present improves and disappears over the first
few weeks.
