cleft lip

A cleft lip is a birth defect where the tissue forming the lip doesn't fuse properly during early pregnancy, resulting in a split or opening in the upper lip. This can vary from a small notch to a wide gap that extends into the nose. It may occur alone or with a cleft palate. Causes can include genetic factors, environmental influences, or a combination. Treatment typically involves surgery to close the gap, often followed by additional procedures and therapy to improve function and appearance. Early intervention and multidisciplinary care help ensure the best outcome for affected individuals.
