Is this swelling or hanging columella, 9 months post Rhinoplasty? (photos)

It is difficult to advise with current photos, most likely you are still experiencing swelling but contact your surgeon and discuss your concerns with your rhinoplasty.

Thank you for your question and photos. At 9 months postop, it is still possible to still have swelling of the tip of the nose.  This and the normal postoperative sensory changes are probably contributing to the feeling of hardness at the tip.  The hanging columella issue is much more difficult to address based on your photos.  A hanging columella can be better assessed in the oblique or lateral view.  Discuss this matter further with your surgeon. Best wishes. 

Actually from the photos we really cannot tell how the columella looks in relation to the tip. If you are unhappy you should discuss concerns and possible changes woth your surgeon.
