How much does the tip drop after rhinoplasty?

You have to give yourself some more healing time. Your nose and surrounding areas are going to be swollen for a while and you should be consulting the surgeon that performed the procedure but give yourself some time before going back in so some of it can subside. It can take up to a year for final results.

Some tips may drop more than others. It really depends upon the work that was done and the swelling. The answer is, it is hard to predict.

The nose continues to change for at least the first year after surgery. This is due to swelling and scarring. The tip is usually the last location that swelling disappears, so it can look full or droopy until the edema (swelling) resolves. The internal scarring is what continues to change the shape of the nose for many years going forward. Internal scarring contracts and can pull the nose and change its shape. Stable surgical techniques that preserve the normal anatomy or give it support, will resist scar contracture better, and the result will remain more consistant over time. Ultimately how much it droops when the tape comes off depends on what was done to the tip and how was it supported internally.
