What is grade III cleft lip and palate?

Grade III cleft lip and palate refers to a condition involving clefts of the palate, alveolar bone, and lip, with the lip cleft extending up to the nasal base, often resulting in an unattractive nasal appearance in children. Grade III cleft lip and palate is generally known as complete cleft lip and palate and is the most common congenital deformity in the oral and maxillofacial region. Treatment for cleft lip and palate involves a series of interventions aimed at restoring the normal shape of the upper lip and achieving normal speech function.
