Can nightly use of nasal dilators increase nostril size?

Hello, I had alar reduction in my primary rhinoplasty two years ago and unfortunately I don’t like how small my nostrils are right now.. so I have two questions. 1. Can using Nostril dilators every night can increase the large of my nostrils by stretching the skin? By gradually expansion or something like that.? 2. Is it possible to reverse alar reduction with another surgery? Adding grafts or whatever it takes to get my normal nostrils back? If yes what scars will be left by this? Thank you!
