Smoking before Rhinoplasty - Is quitting 3 week before enough time?

I understand that
quitting is often easier said than done. It is for this reason that I further
advise that patients opt for the two month interval, so they have extra buffer
time to slowly stop the habit and ensure that the nasal tissues are entirely
ridded of nicotine. The nicotine in cigarettes can greatly impair the results
of your procedure and can restrain the blood vessels that line the nose, giving
you unwanted results and potentially altering the perfect nose structure we
have constructed together. It is essential that all my patients heed to this
advise, as it is one of the most important factors in guaranteeing a successful
rhinoplasty.

Its always best not to smoke prior to any surgery. You will heal more quickly and recover faster.  It sound like you don't smoke that much so hopefully it wont be too dificultgood luck!

The surgeon you choose will tell you how long you should refrain from smoking before surgery. In my own practice I asked patients to stop two weeks beforehand for elective cosmetic procedures.

The blood supply to the nose is not as robust as other areas of the face, and is very sensitive to nicotine.  Abstaining from smoking and nicotine containing products before and after surgery is imperative to achieving the optimal results.  Most surgeons will recommend smoking cessation 4-6 weeks before and after surgery.  

When complications occur after plastic surgery, sometimes they are preventable, sometimes they are not. Smoking and/or nicotine use prior to ANY surgery, particularly rhinoplasty can lead to devastating consequencis.  Most of the time this is preventable. I would be honest with your surgeon...you can always delay the surgery if its not enough time off of cigarettes.  I would quit as soon as possible.  In my practice, a month off of nicotine at the least, preferable 3 months if possible.
