Nine patients with obstructive sleep apnea who underwent unsuccessful palatopharyngoplasty (PPP) as documented by polygraphic monitoring had abnormal cephalometric roentgenogram measurements. Findings indicated a small posterior airway space and inferiorly placed hyoid bone. Cephalometry performed with appropriate techniques to investigate soft tissue location should be obtained systematically in obstructive sleep apneic patients before any surgery is performed. The roentgenogram finding is a helpful guide in deciding whether PPP alone or PPP in combination with other surgical procedures would be more efficacious.
经多导睡眠监测记录显示，9例接受腭咽成形术（PPP）但手术失败的阻塞性睡眠呼吸暂停患者的头影测量X线片结果异常。结果表明气道后间隙狭小，舌骨位置偏低。在对阻塞性睡眠呼吸暂停患者进行任何手术之前，都应系统地采用适当技术进行头影测量，以研究软组织位置。X线片结果有助于指导决定单独进行PPP还是将PPP与其他外科手术联合使用会更有效。
