Shell I Risk 4th Rhinoplasty/revision? (photo)

ASAP, give up fillers, you are damaging the tissues and making more difficult, riskier and eventually at a certain point unfeasible your revision rhinoplasty.Based on the images I have to doubt you major deformity is due to a simple medical surgery on you like, I guess, a septoplasty; since there are sever damages like a saddle nose deformity in extreme grade, a total collapse and pinching of the nose, a iatrogenic short nose, open roof deformity, inverted V deformity, upturned nose to to massive over resection of structures, and a long etc.Your case is of very high difficulty, but can be fixed, actually I have done worse cases and in wost multioperated tissues; my first advice is stopping the fillers or other injections right away, they show poor medical manage and null understanding of the risks associated to them, which are aggravated in poorly vascularized tissues like in your nose.You'll need, due to the massive shortfall of structures, probably rib grafting, so seek the help of a surgeon comfortable with this option, its delilcate harvesting and its artistic sculpting.For a more in detail assessment you could post better images, unblurred and from all angles.Seek the advice and hands of a serious professional who offers to you a time-consuming and expensive procedure; stay far from minimally invassive snake-charming procedures, synthetic implants, fillers, wrapped diced cartilage, etc.
Difficulty 9 out of 10 in revision rhinoplasties, surgical time about 6 hours (in expert hands, could be even longer).
See the link below to find few cases of my own practice very similar to yours which I had the opportunity to operate successfully on, sharing a lot of common features with the technical problem you have posted.
If you wish better grounded opinion well lit, focused and standard images have to be assessed: frontal, both lateral and both oblique views, also from underneath.
Feel free to request any additional information from me.

You could achieve improvement with a fourth rhinoplasty, third revision.  There is obviously loss of support that will not be corrected temporarily or permanently with injectable fillers which only camouflage the problem.  Because of the number of previous surgeries there is probably very little cartilage remaining in the septum that could be used to reconstruct your nose.  This would more than likely necessitate the use of rib cartilage to strengthen the nasal dorsum and create a more natural and less turned up or infantile appearance to the nose.  With the degree of apparent over resection, I would expect your nose to continue to deteriorate over time and encourage you to seek consultation regarding revision surgery relatively soon so that more permanent contracture of the skin envelope does not occur, which would compromise any revision surgery.
