Among the congenital anomalies of the maxillofacial system, cleft lip and palate are the most common, this pathology occurs in 1:800 babies, and in industrially developed regions, their occurrence is slightly more frequent and is 1:500/1:450. The correction process of these congenital anomalies causes many difficulties because they are combined with other organs, especially nervous system anomalies. Anatomical changes in the facial system cause functional deficits in the voice and speech system. The severity of anatomical and functional disorders directly depends on the type of upper lip cleft.
