To determine the association between cephalometric measurements and polysomnographic parameters in Brazilian patients with midface deficiency. This was a primary, clinical, observational, longitudinal, retrospective, analytical, and single-center study. Forty-eight patients with midface deficiency were divided into two groups as follows: those who underwent surgically assisted rapid palatal expansion (SARME) and those who received maxillary advancement (MA). Pre- and post-operative cephalometric and polysomnography measurements were obtained. Pearson's correlation was used to verify the presence of any significant associations between PSG scores and cephalometric measurements. Associations between BMI (Body Mass Index) and AHI (Apnea Hypopnea Index) as well as arousals were observed. In the SARME group, associations between AHI and SNA, UAS and MP-H, arousals and SNA, and Co-A and MP-H were noted. Associations between AHI and Co-A, PoOr-A and MP-H, arousals and UAS, and between minimum saturation of O2 and SNA, SNB, and Co-A were observed in the MA group. This study demonstrates the alterations in the middle third of the face that were related to sleep disturbance. In addition, it shows the associations between the polysomnographic parameters and the cephalometric representations corresponding to the analyzed deformities and transverse or anteroposterior maxillary deficiencies.
探讨巴西面中部凹陷患者的头影测量值与多导睡眠图参数之间的关系。方法：这是一项主要的、临床的、观察性的、纵向的、回顾性的、分析性的、单中心研究。将 48 例面中部凹陷患者分为两组：行手术辅助快速腭扩张术（SARME）组和上颌骨前徙术（MA）组。分别获取术前和术后的头影测量和多导睡眠图测量数据。采用 Pearson 相关分析来验证 PSG 评分与头影测量值之间是否存在显著相关性。观察 BMI（体重指数）和 AHI（呼吸暂停低通气指数）与觉醒次数之间的相关性。在 SARME 组中，AHI 与 SNA、UAS 和 MP-H、觉醒次数与 SNA 和 Co-A 之间存在相关性。在 MA 组中，AHI 与 Co-A、PoOr-A 和 MP-H、觉醒次数与 UAS 之间以及 O2 最低饱和度与 SNA、SNB 和 Co-A 之间存在相关性。结论：本研究表明，面中部凹陷与睡眠障碍相关的中间部分的改变。此外，还显示了多导睡眠图参数与分析畸形和横向或前后向上颌骨不足相对应的头影测量值之间的相关性。
