Unwanted side effects of a rhinoplasty.
From the picture it it appears that there is been over resection of the dorsum of the nose in damage to the upper lateral cartilages. I think you will need a secondary rhinoplasty to correct both the aesthetic and functional problems. I would agree that you need to find a surgeon very experienced rhinoplasty.
Multiple Problems after Rhinoplasty
I agree that there are multiple problems after your original rhinoplasty. Find a rhinoplasty expert who specializes in revision surgery to correct the asymmetry, lift the hanging columella, augment the low bridge, and reduce the fullness above the tip. You can achieve a natural non-surgical result.
I specialize in noses, and it appears you have a polybeak deformity as well as a twisted tip.
I revise these although they are difficult.
Best of luck.
Based on your photos, it appears you are in need of a reconstructive Rhinoplasty. It appears that you have had trauma to your nose. Consult with a Board Certified Plastic Surgeon that is very experienced in this surgery for a good result. Best wishes!
