introduction
Are the most common major congenital Craniofacial abnormality
Cleft lip present in approximately 1 in 700 live births
male to female 2:1 while cleft palate present approximately 1 in
2000 live births and effects male to female 1:2

Embryology At approximately 6 weeks of human embryologic development the median nasal prominence fuses with the lateral nasal prominences and maxillary prominences to form the base of the nose , nostrils , upper lip, and premaxilla ,the confluence of this interior components becomes the primary palate , when this mechanism fails , clefts of the lip and /or maxilla occur At approximately 8 weeks of the fetal life the palatal shelves elevate beside the tongue , then the tongue descend inferiorly and interiorly with the developing mandible , the vertical palatal shelves movie horizontally to fuse with the septum to form the intact secondary palate ,when the palatal shelves fails to fuse a cleft of the secondary palate occurs

Hard palate closure
Advantage of early closure Better feeding ,hygiene , development of phonation Preserve auditory tube function Improve psychological state for baby and his
parents Disadvantages of early closure Difficult surgery due to small structures Growth restriction of maxilla due to scar formation
