Research Abstract	The present study aimed at evaluating 3-dimensional facial soft tissue surface changes during posed smiling in men with a repaired unilateral cleft lip/palate. The sample consisted of 2 groups: the Cleft and Control groups. For each participant, we obtained 3D facial images at rest and at the peak of posed smiling. The results of the statistical comparison showed that the Cleft group exhibited smaller nasal alar protrusions and perioral retrusion during smiling than the Control group.
