This document discusses cleft lip and cleft palate, including definitions, causes, types, complications, and management. Cleft lip is a congenital anomaly where the upper lip is split due to failed fusion of the maxillary and medial nasal processes. Cleft palate occurs when the lateral palatine processes fail to fuse, resulting in a split in the roof of the mouth. Causes may include genetic and environmental factors. Complications can include feeding difficulties, infections, speech problems, and impaired development. Surgical repair of cleft lip is usually done between 2-3 months, while cleft palate repair typically occurs between 1-2 years of age.
