目的:通过数字化影像研究正常人软腭的形态,为腭裂修复的研究提供参考。方法:对200例正常人的数字化头影侧位片进行分析,观察软腭在静止状态下的影像特点,测量并比较不同类型软腭的长度,分析不同年龄组及性别组间构成比的差异。结果:软腭在静止状态下数字化影像中表现为6种类型。两年龄组间及两性别组间各类型构成比均有显著性差异。短粗型软腭的长度明显小于除内钩型外的其他各型,而其他各型间软腭长度均无统计学差异。结论:在数字化头影侧位片中,正常人软腭的静态形状呈多样性。 Objective: To study the morphology of soft palate in normal people by digital imaging and provide reference for the study of cleft palate repair. Methods: The digital cephalometric images of 200 normal subjects were analyzed. The imaging features of the soft palate at rest were observed. The lengths of different types of soft palate were measured and compared. The differences in composition ratio between different age groups and sex groups were analyzed. Results: There are six types of soft palate in the digital image at rest. There were significant differences in the constituent ratios between the two genders and between genders. The length of the stubby soft palate was significantly smaller than that of the other types except the internal hook, while the other paw lengths were not statistically different. Conclusion: In the digital cephalometric films, the normal shapes of soft palate are diverse.
