How long does chin swelling last after surgery?

Just like other facial surgical procedures.  Most swelling will come down within the first 3-4 weeks, but there might be residual swelling for many months after that.

Typically you can fly in a day or two. I like to see my patients at day 5 to remove tape from the chin and then would say it is ok to follow up in a month. With an implant there is always an inherent risk of an infection so you would have to fly back if it happened. The swelling lasts for 10 days or so. 

Hi there! 
Initial swelling after Chin Augmentation or Chin Shaping goes down within the first couple of weeks however residual swelling can take several months to subside, particularly as swelling tends to travel down to the lower pole of your face. Flying a few days after a surgical procedure can be safe, but be sure to consult your surgeon and gain advice on the safest way to go about this post-operatively. Good luck.
Kind regards,

 Most of the visible swelling has subsided after two weeks. It is certainly acceptable to fly an airplane as long as the healing process is going well. Always best to check with your surgeon about traveling After surgery. Full healing takes several months.

With any surgery you will have some swelling.  Using ice for 48 hours will greatly reduce this.  You may notice swelling after a week or so,  but others will not.  It is usually safe to fly within a couple of days post op.
