Thanks for your question. I echo some of the sentiments of the doctors who replied. Whilst threads and fillers can be efficacious to effect a change in the nasal dorsum and improve tip projection, it may at best camouflage it, but it would not reduce bulbosity of the tip.
One of the reasons why patients undergo an open rhinoplasty is to create a more refined tip. This is done with careful debulking of the nasal tip, while preserving blood supply to the nose and using well placed sutures to manipulate the nasal cartilages to create a refined and projected nasal tip. If the tip bulbosity continues to bother you, I would suggest an in person consultation with a plastic surgeon that specialises in rhinoplasty. We have 3D software these days that are able to perform a before and after simulation for you to see the possible changes that can be done.
Hope this answers your questions! Have a great week ahead!
