I am six months post primary rhinoplasty with a rock hard tip and columella. Will septal cartilage grafts used soften over time?

It can take up to a year for the nasal tip and columella to soften. It depends on the grafts used as well. A lot of cartilaginous grafts can render the tip stiff permanently. RegardsDr. J

Nasal tips almost always feel hard for several months after rhinoplasty. This is due to the common practice of adding a strut graft to strengthen the Columella to prevent the tip from dropping with time. It can take a year to soften and usually never gets as soft as pre-op.

Your doctor is 100% right.  It can take time for the tip to soften up - but it will.  It all has to do with not only what was done under the nose (how much maneuvering had to be done, what grafts were placed, etc), but also your propensity for swelling, your ability to heal, what kind of skin you have, etc.  I personally have seen it stay stiff for up to a year before fully softening up later on.  It will come.  Remember, things heal best by resting.  However, the nose is intrinsically connected to many muscles of facial expression and, as such, does not have that luxury.  It is continuously moving when you smile, when you talk, when you sip your coffee.  It just takes time! Until then, enjoy your new nose!
