Abstract

Abstract: Objective: To explore the relationship between facial grimace and velopharyngeal closure ratios in patients with velopharyngeal insufficiency after cleft palate surgery. Methods: Medical records and speech evaluation videos of 68 patients from September 2020 to January 2023 with velopharyngeal insufficiency after cleft palate surgery were collected. The characteristics of nasal air emission and facial grimace were analyzed. The degree of velopharyngeal closure ratios was analyzed and calculated through videos of nasopharyngeal fiberscope.Results: Thirty-six (52.9%) patients showed the incidence of facial grimace, the change of alar muscle movement in patients with facial grimace was greater than that in patients without facial grimace. The proportion of patients with inaudible nasal air emission, audible nasal emission, and nasal turbulence presenting facial grimace was 7 (35.0%), 24 (75.0%), and 5 (31.3%), which had statistically difference (P<0.05). The proportion of facial grimace in mild, moderate, and severe velopharyngeal insufficiency was 7 (38.9%), 25 (73.5%), and 4 (25.0%), which had statistically difference (P<0.05). Conclusion: The incidence of facial grimace was higher in patients with audible nasal air emission with velopharyngeal insufficiency. Patients who showed facial grimace may have moderate velopharyngeal insufficiency.
