Q36: Cleft lip

Cleft lip is a birth defect that occurs when a baby's lip or mouth does not form properly during pregnancy. This condition can vary in severity, ranging from a small notch in the lip to a large opening that extends from the lip up into the nose. A baby can have a cleft lip, a cleft palate (split in their mouth's roof), or both — they may occur on one or both sides of the mouth. The exact cause of cleft lip is unknown, but it's thought to result from a combination of genetic and environmental factors. It's not contagious and cannot be caught from someone who has it. Symptoms are visible and may include difficulties with eating and speaking, or ear infections. The condition can alter the normal growth and development of the face, which may lead to dental problems and difficulties with speech and language development.
