Nostril reduction surgery (called Alarplasty / Alar Base Reduction) is a procedure that can narrow the width of the nostril base, decrease the amount of nostril flaring, or decrease the size of the nostrils. To accomplish this, the surgeon makes an incision in the crease where the nostril wall meets the cheek. A wedge shaped piece of nostril wall is removed, and when the incision is sewn closed, the nostril narrowing is achieved. Alar base reduction is typically performed as the very last step in rhinoplasty. After all of the changes are made to the nose, your surgeon should then analyze the nostril width and flare. If these factors need to be improved, then the surgeon usually proceeds with an alarplasty. It is possible to perform this procedure alone or as part of a rhinoplasty. It can be performed alone, but keep in mind that in order for the nose to appear natural, it must adhere to certain proportions and also be in balance with the other facial features. To get a better understanding of how your nose might look after surgery, your surgeon should be able to show you computer images that will simulate the proposed results of surgery. Recently, 3D imaging has become available and allows patients to visualize the changes from multiple angle.s
