Abstract：
Sleep-disordered breathing affects children\'s growth and development, mental health, and learning ability. Postoperative scarring causes anteroposterior and vertical developmental disorders of the maxilla. Obstructive apnea is likely to occur due to the influence on the maxillofacial and airway morphology. In this study, we investigated the sleep-respiratory dynamics of school-aged children with unilateral cleft lip and palate by performing a simple overnight sleep study, maxillofacial morphology, airway analysis using lateral cranial radiographs, and model analysis. Children with unilateral cleft lip and palate showed a significantly higher respiratory event index (REI) than normal children; the maxilla was located in the posterior position in terms of maxillofacial morphology and airway morphology showed narrow values for all distance measurement items. Moreover, the width and length of the dental arch and the width of the alveolar base arch were significantly smaller. Furthermore, REI and SNA, ANB, and REI were negatively correlated with alveolar base arch width. Children with unilateral cleft lip and palate are more likely than normal children to develop sleep-disordered breathing due to increased airway resistance caused by undergrowth of the maxilla and narrowing of the upper airway and oral volume.
摘要：
睡眠呼吸紊乱会影响儿童的生长发育,心理健康,和学习能力。术后瘢痕形成会导致上颌骨的前后和垂直发育障碍。由于对颌面部和气道形态的影响，可能会发生阻塞性呼吸暂停。在这项研究中,我们通过进行简单的夜间睡眠研究，调查了单侧唇腭裂学龄儿童的睡眠呼吸动力学，颌面部形态学，使用侧颅X光片进行气道分析，和模型分析。单侧唇腭裂患儿的呼吸事件指数（REI）明显高于正常儿童；上颌骨位于后位，颌面形态和气道形态在所有距离测量项目中均显示狭窄值。此外，牙弓的宽度和长度以及牙槽基弓的宽度明显较小。此外，REI和SNA,ANB,REI与牙槽基弓宽度呈负相关。单侧唇裂和腭裂的儿童比正常儿童更容易出现睡眠呼吸紊乱，这是由于上颌骨生长不足和上呼吸道和口腔容积变窄引起的气道阻力增加。
