Cleft lip and palate (CLP) is a facial defect that is represented as a split in the mouth, palate or both. In the United States approximately 4440 babies are born with CLP annually. More than US$600 million are spent on their treatment and mostly on surgical interventions. Considering the high expenses of primary palatal repair, its effect on growth has been controversial. Surgical scaring is postulated as the cause of maxillary hypoplasia. However, this operation has been considered necessary for function and development of speechHowever, this operation has been considered as necessary for better functional and speech outcomes. Materials and methods: Twenty-seven 3dMD facial scans (Atlanta, Georgia) for CLP patients and controls were acquired [Group1 (Midline Palatoplasty) =9, Group 2(two-flap palatoplasty) =9 Group 3(control)=9]. Thirty-one facial measurements were plotted using 3dMD-Vultus Software (Atlanta, GA). The Pittsburgh Weighted Speech Scale was used to score speech. Results: Facial proportion was significantly different in both groups. Speech was “good” in 94% of the patients. Conclusion: Vertical growth was affected in both surgical groups when compared to control.
