What is the pathophysiology of the cleft lip?

Lip cleft can occur as one sided (unilateral) or two sided (bilateral). It is due to the failure of fusion of the maxillary and medial nasal processes (formation of the primary palate).

What causes cleft lip embryology?

Cleft lip results from a failed merging of the maxillary and medial nasal elevations on one or both sides due to the inadequate migration of neural crest cells. Cleft palate results from the failure of the lateral palatine processes to meet and fuse with each other.

What causes a cleft palate anatomy?

What are the mechanics by which cleft lip and cleft palate occur during fetal development?

Can you tell if your baby has cleft lip ultrasound?

Cleft lip may be detected with ultrasound beginning around the 13th week of pregnancy. As the fetus continues developing, it may be easier to accurately diagnose a cleft lip. Cleft palate that occurs alone is more difficult to see using ultrasound.

This process is called vasoconstriction (closing off of blood vessels). When the blood vessels constrict, the blood supply is compromised, delivering less oxygen to the tissues of the palate. With low oxygen, the palate lining begins to die and shrink away leaving a perforation (or hole in the palate).

What bones are affected with cleft lip and palate?

Which structures do not fuse with a cleft palate?

A cleft of the hard palate occurs as a result of the failure of fusion of the lateral palatine processes, the nasal septum, or the median palatine processes. When a cleft of the soft palate occurs, the uvula is often split (bifurcated).

What is the difference between cleft lip and cleft palate?

A cleft lip is an opening in the upper lip; a cleft palate is an opening in the roof of the mouth. In both cases, an opening forms because the facial structure doesn’t close completely during development. A child can be born with one or both of these conditions.

How does the palate develop?

Formation of the palate The palate develops from fusion of the primary and secondary palate (Fig. 11.9C). The primary palate is derived from the intermaxillary segment and the secondary palate formed by two palatine processes or palatal shelves from the maxillary prominences.

How do you get cleft lip?

What Causes Cleft Lip? During the first 6 to 10 weeks of pregnancy, the bones and skin of a baby’s upper jaw, nose, and mouth normally come together (fuse) to form the roof of the mouth and the upper lip. A cleft lip happens when parts of the upper lip and/or gum do not fuse together completely.
