Cleft Lip and Palate are twice as common in
boys as in girls
Isolated Clefts of Palate are more common in
girls
75% of Clefts are Unilateral, rest are Bilateral
Left side is more frequently involved

5. The medial nasal swellings
enlarge, grow medially
and merge with each
other in the midline to
form the intermaxillary
segment

before 18 months had hypernasal speech,
articulation errors, or required secondary surgery
to correct speech
