A cleft lip is a facial birth defect in which a baby is born with an opening or gap in the upper lip. This gap can vary in size and severity and may occur on one or both sides of the lip.

Cleft lips develop during early pregnancy when the tissue that forms the lip does not fully come together. The exact cause of cleft lips is not always known but can result from a combination of genetic and environmental factors.

Treatment for a cleft lip typically involves surgical repair, often performed when the child is a few months old, to close the gap in the lip and restore a more normal appearance. Multiple surgeries and ongoing medical care may be necessary as the child grows to address any associated issues with speech, dental development, and facial appearance.

It is essential to approach discussions about medical conditions, especially congenital anomalies, with sensitivity and use respectful language to avoid stigmatizing or marginalizing individuals affected by such conditions.
