Abstract

Abstract: Objective: To investigate the relationship between soft palate and velopharyngeal closure function after incomplete cleft palate surgery through the application of lateral head X-ray in the evaluation of velopharyngeal closure function after incomplete cleft palate surgery. Methods: Forty patients with incomplete cleft palate surgery (VPC 15 cases, MVPI 10 cases, VPI 15 cases) from January 2017 to December 2019 who had undergone one-stage cleft palate surgery for more than half a year were selected as the research object, 10 normal cases were set as control group. Their head lateral X-rays were collected and analyzed. Results: The overall distribution of PU, PW, the need ratio, BC/BD, and ∠B₂PC₂ in the normal group, VPC group, MVPI group, and VPI group were statistically different (P<0.05). And the following cut-off point, i.e. PW≥23.50 mm, the need ratio≥0.81, PU≤23.50 mm, sagittal soft palate closure degree≤0.858, and ∠B₂PC₂≤29°, could be considered as significance of clinical diagnosis. Conclusion: The velopharyngeal closure function after cleft palate surgery is closely related to the length and mobility of the soft palate. Postoperative lateral head X-ray examination can be used to evaluate the patient's velopharyngeal closure function.
