Q

Cleft Lip and Palate (cause, prevalence):

A

Failure of processes to merge. Prevelance: Native American, Asian, White, Black.
Lateral: Maxillary and Mandibular.
Oblique: Lateral nasal process and Maxillary.
Cleft Lip: Maxillary and medial nasal.
Median Cleft: Two medial nasal processes.
CP= failure of palatal shelves to fuse (bifid uvula is minimum manifestation) if syndromic its CP only, if nonsyndomic (more common) its CP and CL.
Submucosal cleft= palate shelves get close enough that the mucosa cover it but bones aren’t fused.
