Influence of involuntary facial expressions on reproducibility of 3D stereophotogrammetry in children with and without complete unilateral cleft lip and palate from 3 to 18 months of age.

Facial 3D stereophotogrammetry is a useful tool for monitoring facial growth longitudinally in young children with facial deformities, as no radiation is involved and image capture is easy and fast. It can be performed reliably in children with and without UCLP aged 3-18 months by an experienced photographer utilising a meticulous image capturing protocol.
