Cleft lip is a common birth defect. For postoperative articulation training of cleft lip, we can first help the children to practice the muscle activity of soft palate and pharynx, and then strengthen the articulation practice. 1. Exercise the muscle activity of soft palate and pharynx: blowing method can be applied, this method is simple and effective, you can use glass tube to blow water bubbles or soap bubbles or practice blowing balloon, flute, trumpet, harmonica, etc., and at the same time, you also need to practice the muscles of lips and tongue. 2. Practice pronunciation exercises: the practice of monophthongs can be trained in accordance with the Hanyu Pinyin method. When practicing the pronunciation of letters, you can be supervised and corrected by a professional instructor, and practice over and over again. Once you can accurately pronounce vowels and consonants, you can start practicing the pinyin of single words. Practice sentences or further conversations based on pinyin, try to read each single word as clearly as possible, and gradually increase the speed when reading utterances. Most of the children with cleft lip can have normal speech development and habits, and only through comprehensive treatment can they fully recover. Regarding pronunciation training after cleft lip surgery, it is recommended that the children go to the hospital for specific consultation.
