Study Notes

Submucous Cleft Palate:

Occurs when the oral surface of the secondary palate is completely formed, while the nasal surface (or just the uvula) is incomplete.
Classic triad of characteristics includes a bifid or hypoplastic uvula, thin bluish area in the middle of the velum, and a notch in the hard palate.
Muscles of a submucous cleft are often affected in the same way as with a complete cleft palate.
May include a minor abnormality of the uvula or a defect of the nasal surface of the velum and hard palate.
Velopharyngeal insufficiency, feeding problems, and Eustachian tube malfunction are some of the functionally affected areas.
Can be overt or occult, with the latter being visible only through nasopharyngoscopy.

Facial Clefts:

Two types of facial clefts: oblique and midline.
Can be caused by genetic defects or amniotic bands.
May include various anomalies of the face and skull.
Affects cognition, language, speech, resonance, hearing, feeding, and swallowing.
Cleft lip/palate is the fourth most common birth defect and most common congenital defect of the face.

Incidence of Clefts:

Prevalence of cleft lip/palate is about 1/600 in the United States.
Racial differences in recurrence risk: Indigenous American Indians > Asians > Caucasians > African descent.
Cleft lip (with/without cleft palate) occurs twice as often in males, while cleft palate occurs twice as often in females.
Incidence of submucous clefts is essentially unknown because it often does not cause any problems.

Treatment of Clefts:

Cheilorraphy for lip repair and palatoplasty for palate repair are the most common treatments.
