The position of the hyoid bone, which anchors much of the tongue musculature, is often abnormally low in patients with obstructive sleep apnea syndrome (OSAS). Cephalometric measurements, frequently used to measure SNA and SNB angles, can also provide information on the posterior airway space (PAS), the mandibular plane, and the hyoid bone. This information is useful in determining the appropriate surgical treatment for OSAS patients.
舌骨固定着大部分舌肌组织，在阻塞性睡眠呼吸暂停综合征（OSAS）患者中，舌骨位置常常异常低下。常用于测量SNA和SNB角的头影测量法，也能提供有关后气道间隙（PAS）、下颌平面和舌骨的信息。这些信息对于确定OSAS患者合适的手术治疗方法很有用。
