Reducing the Size of the Nostrils with Rhinoplasty or Nasal Surgery in Los Angeles
Reducing the size and width of the nostrils can significantly improve of the outcome of a rhinoplasty in people who have flared and wide nostrils. Using an Alar wedge resection technique during rhinoplasty, a small wedge of the nostril is removed and the remaining nostrils are brought in to make the width narrower. this technique of nose surgery does not alter the upper lips.
As the other surgeons have said, removing some of the nostril sill won't change the length of the upper lip. However, there may be some optical illusion that could be perceived as a change in upper lip dimensions.
No, alar base reduction, or bringing the nostrils closer together would not be able to decrease the horizontal size or width of the mouth. The alar base, of the nose, sits on the very superior aspect of the circular muscle beneath the lips and as such really would not have that type of effect on the size of the mouth.
