What would be the most effective and least expensive procedure that would workout for my nose? How much would it cost?

This should be treated with rhinoplasty, it is the best option for improvement.  Fillers can camoflage the area but will not make as large an impact and may make the nose look more full.  Please see a rhinoplasty expert.  Best, Dr. Emer.

Thankswith either open or closed rhinoplasty, you should get good results!Best wishesJ TaheryOtolarynglogist/Facial Plastic SurgeonChesterUK

 A closed rhinoplasty procedure can address shaving down the dorsal bump. Since you're only 17, you will need parental consent to undergo the procedure. For many examples, more information and our current price list for rhinoplasty, please see the link and the video below
