目标 对于狭窄的上颌牙弓和上颌骨骼收缩对阻塞性睡眠呼吸暂停 (OSA) 发展的影响，人们知之甚少。因此，本研究的目的是阐明日本男性患者上颌牙弓宽度与 OSA 之间以及上颌骨收缩与 OSA 之间的关系。方法 为 164 名日本男性 OSA 患者制作研究模型进行牙弓分析。我们将患者的牙弓宽度与日本男性的标准值进行了比较。此外，还检查了上牙弓宽度与呼吸暂停低通气指数 (AHI)、体重指数、骨骼模式（SNA、SNB 和 ANB）、从直立头颅侧位片获得的舌头横截面积、下牙弓宽度、覆牙合和覆咬合之间的关联。 结果 尽管较窄的上牙弓与较严重的 OSA 有关，但 OSA患者的上牙弓并没有明显窄于日本标准值。然而，多元回归分析的结果显示，由于下颌相对于上颌骨位置更靠后，上牙弓变得更窄。结论我们得出的结论是，上颌牙弓收缩可能与 OSA 的发生有关，但这并不是我们日本 OSA 患者样本的典型特征。而且，加重OSA的因素不是上颌骨骨骼收缩，而是与前后骨骼差异相关的上颌牙弓收缩。
OBJECTIVES Little is known about the contributions of a narrow maxillary dental arch and maxillary skeletal constriction to the development of obstructive sleep apnoea (OSA). Therefore, the purpose of this study was to clarify the relationships between maxillary dental arch width and OSA and between maxillary skeletal constriction and OSA in Japanese male patients.METHODS Study models for 164 Japanese male OSA patients were fabricated for dental arch analyses. We compared the patients' dental arch widths with the standard value for Japanese males. Moreover, the associations between the upper dental arch width and the apnoea-hypopnoea index (AHI), body mass index, skeletal pattern (SNA, SNB, and ANB), cross-sectional area of tongue obtained from an upright lateral cephalogram, lower dental arch width, overjet, and overbite were also examined.RESULTS A lthough a narrower upper dental arch was associated with severer OSA, the upper dental arch in OSA patients was not significantly narrower than the Japanese standard value. However, the results of a multiple regression analysis revealed that the upper dental arch became narrower as the mandible was positioned more rearward relative to the maxilla.CONCLUSIONS We conclude that dental arch constriction in the maxilla could be associated with the development of OSA but is not a typical feature of our sample of Japanese OSA patients. Moreover, the factor that aggravates OSA is not maxillary skeletal constriction but rather maxillary dental arch constriction related to antero-posterior skeletal discrepancy.
