Wearing plastic nasal cones - does it help with collapsed, narrow, uneven nostrils? (Photo)

Thank you for your question.  Unfortunately, wearing these will not have any lasting effect for you.  They will not change the shape or strength of your ala or nasal sidewalls.  I occasionally ask patients to wear these after a revision procedure where I am opening a scarred nostril and I want the nostril to heal without scarring back down.  But, they will not permanently open a nose that is already healed.  If you don't mind wearing these, then you certainly can continue long term, but if you want to seek a more permanent solution, you would have to undergo revision rhinoplasty with cartilage grafting to approximate the effect of the cones.

Your  photos confirm narrowing of your nostrils. An examination would help to determine how pliable the nostril tissue is and also if other causes of nasal collapse are involved. Certain cartilage grafting techniques may help.
