Anatomic Growth Modelling of Cleft Palate Shape

The aim of this project is to utilize computer vision technology to develop algorithms for anatomic growth modelling of cleft lip and palate after surgical correction. Two plaster cleft models (3 months old, before surgery, and 9 months old, after surgery) from the same baby were first scanned with a Minolta VIVID 900 3D scanner. Landmark points were then indicated on the 3D images of each plaster model using the software RAPIDFORM 2002. Translation matrices (from 3 to 9 months) were then defined using these landmark points. It was observed that after surgical correction, the gap of the cleft lip and palate decreased in size, while the surface area of the major and minor segments increased. This project, using RAPIDFORM 2002, provides good visualisation and understanding of anatomic growth modelling of cleft lip and palate to the clinician.
