Abstract: PURPOSE: To observe the effects of PNAM orthodontics combined with Noordhoff operation on cleft lip and palate in children. Methods: From March 2016 to August 2017, 120 patients with cleft lip and palate were divided into two groups according to the random number table. Each group had 60 cases. Patients in the experimental group were treated with PNAM orthodontics combined with Noordhoff operation, and patients in the control group were treated with PNAM orthodontic treatment. SPSS 20.0 software package was used for comparison between the two groups. Results: The cure rate of the experimental group (95.00%) was significantly higher than that of the control group (83.33%); pronunciation accuracy of the two groups was significantly improved (P<0.05), and the pronunciation accuracy score of the experimental group was significantly higher than that of the control group (P<0.05); the transverse distance of BK, BK connection, sagittal line and MC-sagittal line of the two groups were significantly decreased. The transverse distance of BK, BK connection, sagittal line and MC-sagittal line in the experimental group were significantly lower than those in the control group (P<0.05). The J-(F-G) of the two groups was significantly increased, and the J-(F-G) of the experimental group was significantly higher than that of the control group (P<0.05). There was no significant difference in the incidence of infection between the two groups ( χ2=1.031, P=0.309); Parents' satisfaction rate of the experimental group (93.33%) was significantly higher than that of the control group (71.67%). Conclusions: PNAM orthodontics combined with Noordhoff operation in the treatment of cleft lip and palate children can effectively improve the situation of cleft maxilla and enhance the accuracy of children's voice. It has good safety and high satisfaction of parents, and It is worthy of wide application in clinic.
