Application of Modified V-Y Advancement Flap in Alar Base Reduction

A variety of techniques for alar base modification have been described in the literature. Limitations of these techniques include scars, recurrence, asymmetry, etc. An incorrect excision of the lateral alar wall can result in a tear-drop or Q-shaped deformity.

In this study, a modified V-Y advancement flap will be introduced that will avoid the complications discussed above as well as adjust the positional relationship between the nasal alar and the columella using this technique. In addition, this method is reversible; once the nostril is narrow due to excessive advancement of the flap, the reverse V-Y advancement method can be used to enlarge the nostril.

In this study, a retrospective review of wide nasal bases in the past 3 years was conducted. A blind analysis of anthropometric points was conducted. There were 3 outcome variables: the width of the alar base, the width of the flare, and the distance between the alar base and columellar base.

The alar base was reduced with a modified V-Y advancement flap on 65 female patients ranging from 18 to 45 years of age. In 10 cases, an "Inclined Y-arm flap" was used to narrow alar bases and adjust columella-alar positions. In the remaining cases, a "Horizontal Y-arm flap" was performed to narrow the simple nasal alar width. In all cases, the nasal base was reduced without distortion. In the postoperative period, all the effects were seen to persist for a long time, and patients were generally satisfied with the results of the procedure.

By using this modified V-Y advancement flap technique, the incision can be concealed as thoroughly as possible, thereby avoiding "tear-drop" or "Q" deformities as well as narrowing the nasal alar effectively. Furthermore, this method, in combination with rhinoplasty surgery, will greatly enhance the nasal appearance.
