Cleft lip

Question:

What is a Brocchal Cleft Lip?

Answer:

I am not familiar with the term "brocchal" that you asked regarding a specific type of cleft lip and could not find it in any medical dictionary.

A cleft lip, with or without a cleft palate (the roof of the mouth) occurs when the tissue that forms the upper lip, does not come together and fuse during embryogenesis (when the baby is forming in utero about 7-8 weeks of gestation). Cleft lip with or without a cleft palate occurs in about 1 in 1,000 infants.

The abnormality can be one sided (unilateral) or can affect both sides of the lip (bilateral). It can also occur right in the midline of the upper lip, but this quite rare. The degree, or how deformed the lip is, can vary. It can be quite mild, only a notch in the lip, or much more severe where the lip is widely open.

Cleft lip with or without a cleft palate has a strong genetic component, thus it can run in families. There are also environmental factors that may cause a cleft lip. Cleft lip with or without a cleft palate is also seen in many genetic syndromes.

There are some genetic syndromes that involve the brachial arches (areas of development in the head and neck of the fetus - which look something like gills in fish). These can develop abnormally. These syndromes may have a cleft lip as part of their features, but these people would also have other abnormalities or problems and not just a cleft lip alone. Perhaps the term you were referring to is "brachial".

If you find more information about the word "brocchal", I would be happy to see if I can find further information as well.
