A cleft lip and a cleft palate, according to the Encyclopedia of Global Health, are congenital deformities that occur in the womb. Cleft lip is an abnormal fissure during development that fails to close the lip and leaves an opening or openings at birth. Cleft palate is a fissure or opening at the roof of the mouth or palate. This opening forms a pathway between the mouth and nasal cavities and can cause speech impairment, infection, and breathing difficulty if not treated. Cleft palate may be one side of the roof of the mouth (unilateral), or both sides of the mouth (bilateral). The opening may be complete or incomplete.
