You asked a few different questions so here are answers: -- can you reduce the size of my alar base without reducing the size of my nostrils-- yes, alar base reduction can be performed a variety of techniques not all of which will reduce the size of your nostril. --can you prevent my nostrils from widening with smiling-- the nostrils are typically widened with smiling. The facial muscles responsible for this are important for several functions so you would not want to sever them. you can prevent a nose from plunging with smiling, but it is much more difficult to prevent your nostrils (alar base) from widening with smiling --can you bring in my (alar base) and make my nostrils wider-- this is a complex three dimensional question which depends on what part of your nose you want wider.
There are a variety of grafts which can be placed in your nose which can help widen the nose in different areas but widening a too narrow nostril is generally one of the more difficult tasks in rhinoplasty --the key to bringing in a wide nose in without it looking unnatural-- planning, surgical experience, knowledge of sophisticated rhinoplasty techniques, etc. Good luck
