Which procedure will help my nose look less wide when I smile? (photos)

There are a few options. One would be a full rhinoplasty breaking the bones to narrow your nose. A second less involved choice would be alar wedge resection. This is where the nostrils are reduced and narrowed. The benefit of this is that it can be done under local anesthesia and has minimal recovery time. Also would be far less expensive.

Procedure for wide tip and nostrils: if the nostrils are wide based, the procedure which narrows the width of the alar base is called an alar plasty. You do not show a view from under the nose looking up at the nostrils, which is called a basal view. This view would be more helpful to address that question. If the tip is also wide, a tip plasty can also be performed. Sometimes however these procedures are performed in conjunction with other aspects of the nose in a full rhinoplasty. You do not show enough views of your nose from enough different angles to make that assessment.
