Effect of V–Y plasty on lip lengthening and treatment of gummy smile

The aim of this study was to assess the effect of isolated V–Y plasty on lip lengthening and the treatment of gummy smile. An isolated V–Y plasty was performed on 14 patients with a gummy smile. In each case, measurements of upper lip length and gingival display were recorded from posed-smile photographs taken preoperatively and at 1, 3, and 6 months postoperatively. Gingival display decreased significantly and lip length increased significantly over all intervals investigated. Applying this technique after Le Fort I surgery may be beneficial; however, as with other injection or surgical lip lengthening methods, its stand-alone application should be questioned.
