2 weeks after ear operation, can a person smoke or not?

Thank you for your question.I would recommend to hold off on smoking for at least 4-6 weeks after your surgery. Smoking will do nothing but impair your ability to heal and could potentially cause an unwanted wound healing complication.Best of luck and hang in there!- Dr. Bryson Richards

Smoking can definitely increase your risk of complications. In general the longer you can wait the better. Obviously, no nicotine is best. 

Your plastic surgeon may have a different opinion, but I think that you will be best off avoiding nicotine. At 2 weeks, the healing process is continuing and any constriction of blood supply will not help. Best wishes for ongoing patience and an outcome that you will be pleased with long-term.
