Rhinoplasty and results
You did not mention when you surgery was. If it was recent, I would say give it at least a year for the swelling to subside.
Revision rhinoplasty candidate for pinched tip
Its very important to have clear expectations before undergoing revision rhinoplasty. To widen the pinched tip requires some cartilage grafting techniques, so it important to know if there is any cartilage left inside the nose from the previous surgery. The supra tip break can also be accomplished either with surgery or with cortisone shots placed in that area in the postoperative period. Since rhinoplasty and revision rhinoplasty are the hardest operations to perform correctly in the entire field of cosmetic surgery, choose your revision rhinoplasty surgeon very wisely based on experience
Correction of Pinched Tip
Pinched tip can cause airway obstruction. Correction of this will require cartilage grafts which are usually taken from the ear. I see your concern. Would love to see profile pictures of you. You are a candidate for a reconstructive rhinoplasty to straighten the nose and reconstruct the tip. Consult with a Board Certified Plastic Surgeon who is highly experienced. Best to you!
