Mucus and Nasal Drip After Rhinoplasty?

The drainage you are experiencing is very normal after rhinoplasty and should subside.  The inflammation that occurs after rhinoplasty causes excessive mucous to be produced to heal the area.  This many persist for up to one month.

It's very common to have clear drainage so soon after a rhinoplasty. You may even notice spontaneous drainage which occurs intermittently for many months after your surgery. Keep in mind that the internal tissues of the nose have been subjected to a fair amount of trauma, and their way of reacting is to swell and drain. As your swelling resolves, so will your drainage. Good luck.

For the first 3-4 weeks after a rhinoplasty, it is normal for the internal tissues of the nose to swell and create copious mucus. As the swelling resolves. so will the post-nasal drip. I advise my patients to avoid blowing their noses.
To improve these problems, moisture in the nose is the best thing you can do.

Sit in a small bathroom with the shower running, the steam will improve the sysmptoms.
Place saline mist or saline gel inside your nose.

This time of year is ideal in most parts of the country because of the increased humidity, just be patient.
