Perbedaan panjang palatum lunak, kedalaman nasofaring, dan Need’s ratio pada maloklusi klas I, II, dan III skeletal

Introduction: Cases of cleft palate, enlarged adenoid, Obstructive Sleep Apnea Syndrome (OSAS), and skeletal craniofacial malocclusion malocclusion often accompanied by soft palate dysfunction. The soft palate length in men is significantly higher than women. The aim of this study is to determine the differences of soft palate length, nasopharyngeal depth, and Need’s ratio in class I, II, and III skeletal malocclusion and its differences between men and women. Methods: This research was analytic observational with cross-sectional method using lateral cephalograms of patients aged between 16 to 40 years old. The samples in lateral cephalogram were obtained and classified through measurement based on Steiner method. The calculation of soft palate length, nasopharyngeal depth and Need’s rati o were determined using Corel-Draw X8 software. Result: The most common type of soft palate was leaf shaped type. Data analysis using ANOVA test showed there was no significant differences in the length of soft palate (p=0,054), the depth of nasopharynx (p=0,617), and the Need’s ratio (p=0,229) between class I, II, and III skeletal malocclusion. The result of independent T-test showed there was a significant difference in the length of soft palate between men and women (p=0,002). However, there was no significant difference in nasopharyngeal depth (p=0,179) and Need’s ratio (p=0,130) between men and women. Conclusion: Soft palate l ength, nasopharyngeal depth, and Need’s ratio had no significant difference in class I, II and III skeletal malocclusion, but there was a significant difference in soft palate length between men and women.
