Parenthesis Tip Deformity After Rhinoplasty

You do have a couple of options, depending on your preference. I would not suggest injection, since the filling effect can also add volume intranasally. Yes, the cartilage may support against this, but the creation of nasal obstruction from filler going deep instead of lifting superficially is a potential. 
From what I can tell from your picture, there are two other options that seem reasonable. One is very straightforward, and would be the most likely answer surgeons may suggest. That is to take a little ear cartilage and use that to support and reshape the ala and supra-alar crease (I can't honestly tell where your maximal depression is on your picture). In any event, that could honestly be done with endonasal incisions, and even under local or oral sedation. Little or no down time.
The second option is about the same scope of involvement, but would take a better evaluation of your current anatomy in person  A few years ago there was a technique published called a J flap, where you can remove a small but precise amount of cartilage and intranasal lining on the lateral extent of the nasal cartilage. It just tightens the ala a little, and lifts that deep supraalar crease. Great, quick, very effective, and even less down time. Normally, it is used to restore the airway. But truthfully someone would have to take a look at you first in order to make sure you are a good candidate for that. 

One can have nasal airway collapse after rhinoplasty and it can happen in both primary and secondary. Most of these can be corrected through an open approach and after the use of grafts for contour correction of the specified area.

The parenthesis tip deformity can be treated by one of two ways. Further narrowing of the actual dome itself and either rim grafts or alar batten grafts placed via closed rhinoplasty technique, provided there is extra cartilage in the nose or on the ear for this. This can be done through closed rhinoplasty in experienced hands.
