2. INTRODUCTION
Cleft lip and cleft palate are congenital
malformations of face resulting from the failure
of fusion of first branchial arch during
intrauterine development .
The complete formation of lip often occurs by
5 to 12 weeks ,whereas the formation of palate
may occur only by 12 to 14 weeks of
gestational age.
These conditions are usually detected at birth
and may be associated with other congenital
anomalies in about 20% of cases .
3. Cleft lip and cleft palate may occur as single or
in combination .it may be unilateral or bilateral.

the floor of the nose .
It is apparent at birth as incomplete formation
of lips.
