Hoffmannova E, et al. - In this prospective morphometric study of UCLP patients, the growth of the upper dental arch following early neonatal cheiloplasty was evaluated. A comparison of selected dimensions was performed with published data on non-cleft controls and on later operation protocol patients. Researchers noted no reduction in the length or width dimensions in association with early neonatal cheiloplasty during the first year of life. Data suggested a natural formative effect of a reconstructed lip on the actively growing anterior parts of upper dental arch segments, which cause narrowing of the alveolar cleft.
