I have extra cartilage on left side of the nose. It's caved on the right. Do I need a revision to make it straight? (Photo)

Being true your problem is congenital, not very common and
atypical... it is hard to understand you still have not been provided a
clue; you suffer BILATERAL INVERTED / CONCAVE LATERAL CRURA OF THE ALAR CARTILAGES.
Normally the lateral cruras are convex, with the belly outwards, flat
in the worst case or with slight concavity; but it is pathologic having
them both or one inverted to the fullest, like a nutshell downwards,
creating the typical pinched look and hollow effect you show in your
images.
There are different techniques suggested by the few surgeons with
wide experience in them; I have personally operated on dozen of such
inversions of cruras. In your case (so assymetrical) it is likely you need full crura
replacement by a hand made graft, however I'd try intraoperatively to
evert it flippling and cross locating, however if this did not work in a
nice shape then I'd carve and tailor a new crura out of concha bowl
cartilage grafting.
The rest of your tip needs also tip plication, correction of the cleft, revision of previos work, also you seem to have supratip and upturned tip.
Beware, let me insist, if you are given any kind of diagnosis or
proposal other than the one above, few surgeons understand this
congenital condition; you might end in a mess of deformity otherwise.
If you wish better grounded opinion please do post or send privately
well lit, focused and standard images: frontal, both lateral and both
oblique views, also underneath the nostrils.
Feel free to request any additional information from me.

 A revision rhinoplasty is more difficult than a primary rhinoplasty, so it important to choose your surgeon  very wisely based upon experience and producing  natural results.  The  nasal tip cartilages appear to have shifted slightly from previous surgery and the shrink wrap  effectss of the skin.  Thin skin present in the tip of the nose tends to have  every little imperfection showing through.  Some minor adjustments can be performed to the nose to make it more symmetrical and refined.

BBle1234,Over time your nasal cartilage may have shifted, or may have been influenced by the contracting of skin and scar over time.  A revision rhinoplasty will be able to fix the contour irregularities around the underlying cartilage, and this may the reason that you are noticing the changes on tip of your nose.  Seek a nasal specialist in revision rhinoplasty.  A thorough nasal examination and consultation will outline the available options for you to achieve your desired results.  Best of luck!Dr. Edween
