Cleft palate is a congenital deformity characterized by an abnormal opening in the roof of the mouth, which can occur in either the hard palate, located at the front of the mouth, the soft palate at the back, or both. This condition arises during pregnancy when the tissues that form the palate do not fuse properly, resulting in a gap that connects the oral cavity to the nasal cavity. Cleft palate may present as an isolated condition or in conjunction with other congenital anomalies, with cleft lip being the most frequently associated defect. The surgical procedure known as palatoplasty is performed to repair the cleft palate, focusing on the soft and/or hard palate. During this operation, the surgeon creates bipedicle mucoperiosteal flaps from the surrounding tissue, which are then carefully manipulated to close the cleft. The procedure involves precise incisions along the lateral edges of the cleft, allowing for the elevation and advancement of the flaps while preserving critical blood vessels, such as the greater palatine arteries. The flaps are sutured together in layers to effectively cover the defect, thereby separating the oral cavity from the nasal cavity. Additionally, the nasal mucosa is repaired using a flap taken from the non-cleft side of the vomer, which is also sutured in layers to ensure closure of the nasal defect. Any remaining open areas are allowed to heal naturally through secondary intention, promoting optimal recovery and function.
