Congenital cleft lip and palate can be treated, and the treated patient is not very different from an adult. For cleft lip and palate, the main treatment method is surgery, together with orthodontic, psychological and phonological treatment, etc. The treatment of cleft lip and palate is a long-term, complex and multidisciplinary process. In the case of unilateral complete cleft lip and palate, for example, repair surgery for cleft lip can be performed first at about 3-6 months of age, and repair surgery for cleft palate can be performed at about 1-1.5 years of age. If the patient’s pronunciation is obviously unclear after surgery, pharyngeal molding surgery can be performed after the age of 4 years for pronunciation, while at the time of eruption of the third tooth, the cuspids, alveolar ridge repair can be performed, while adults can consider nasal deformity and orthognathic surgery.
