Swollen Nose After Rhinoplasty Due to Smoking ?

I can't see how smoking would have a significant effect on swelling after rhinoplasty. Nevertheless, if you want against the instructions of your surgeon you will live with the consequences.

Smoking is bad for healing and may lead to prolonged swelling. That being said, the 3 weeks after surgery are the time of the most intense swelling. After the third week, the swelling starts to come down dramatically. Its difficult to say why your swollen, as everyone is different. For now relax and let the healing take place.

Thank you for the question. You should absolutely consult with your physician about your smoking habits in order to obtain the most reliable and individualized medical advice. Most specialists recommend abstaining from smoking for 2-3 weeks before a rhinoplasty, while others may insist on a full month or two. Smoking will cause irritation and restrict the blood flow to your healing areas, possibly causing complications during the recovery period.   
In addition, you should also make sure to avoid smoking for at least two weeks after surgery as it may interfere with your healing process. Smoking after surgery may restrict the flow of blood to the healing areas, exacerbate swelling, and prolong recovery. If you did experience swelling after smoking, then your best bet is to reach out to your plastic surgeon and see if it can be resolved. Of course, as a physician, I would advise you to quit smoking altogether due to a variety of health risks associated with it. 
 An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and obtain expert medical advice. Best of luck!
