Ideal age for cleft palate surgery in a child is
a. In the embryologic scheme, palatal shelves develop as swellings of the medial maxillary prominences.
b. After downward growth adjacent to the tongue, the shelves become horizontal and fuse.
c. Complete closure of the plate transpires after 12 weeks.
d. Incomplete closure of these palatal shelves will produce cleft palate.
e. Cleft palates can be further distinguished as complete (extension into the nosE. or incomplete (existing midline attachment).
f. Moreover, submucous cleft palate, the most common, is exemplified by three physical findings: bifid uvula, thin membranous central portion, and a posterior palpable notch.
g. Surgical repair is predicated on the separation of oral and nasal cavities and the formation of a tight velopharyngeal valve.
h. Surgical correction must provide adequate palate length and mobility. The timing of repair remains controversial.
i. Early palate repair affords the advantage of improved speech but also exacerbates midface retrusion.
k. In the von Langenbeck procedure, bipedicled mucoperiosteal flaps from the hard and soft palate are raised and closed in the midline.
l. In the pushback palatoplasty, the mucoperiosteal flaps are created by a W-shaped incision .
m. The intravelar veloplasty reorients the musculus levator veli palatini, which has inserted abnormally on the hard palate.
