The relationship between the palatal dimensions and inherited factors such as body height and arachnodactyly, i.e., spider fingers, were studied in a sample of 87 patients with high and narrow palatal vaults, chosen from 1008 randomly selected patients at an orthodontic clinic. The patients with high palates were significantly taller than Swedes of the same sex and age (p < 0.001). Established arachnodactyly was not found in the examined sample. Sucking habits neither seem to influence crowding nor the palatal dimension at the molar region. Mouthbreathing strengthened but was not a pre-requisite for the significant correlation between palatal height and body height. The predominant orthodontic diagnoses included crowding, extreme maxillary overjet and postnormal occlusion as can be expected in a sample of orthodontic patients. The study will serve as a reference material for further investigations of patients with the Marfan syndrome where high palate, high stature and arachnodactyly are important features.
在一家正畸诊所从1008名随机挑选的患者中选取了87名高腭穹窿患者作为样本，研究了腭部尺寸与诸如身高和蜘蛛指（即细长指）等遗传因素之间的关系。高腭患者明显高于同性和同龄的瑞典人（p < 0.001）。在所检查的样本中未发现确诊的蜘蛛指。吮吸习惯似乎既不影响牙列拥挤，也不影响磨牙区的腭部尺寸。口呼吸会加强腭高与身高之间的显著相关性，但不是这种相关性的先决条件。正如在正畸患者样本中所预期的那样，主要的正畸诊断包括牙列拥挤、严重的上颌前突和后正常咬合。该研究将作为进一步研究马凡综合征患者的参考资料，在马凡综合征中，高腭、高身材和蜘蛛指是重要特征。
