Nasal alar reduction surgery is to take out the soft tissue below the skin from the incision in the nostril, so that the alar cartilage on both sides can be contracted and sutured inward to achieve the purpose of reduction and make the nostril smaller and breathable. But you can first determine whether the alar is too large or the alar is hypertrophy. Under normal circumstances, the lateral nostril does not exceed the vertical line of the inner canthus, otherwise it is the alar hypertrophy. I suggest you go to a regular plastic surgery hospital for expert consultation first!
