The progress of medical imaging over the last decades has led to a better understanding of the upper airway structure in sleep-disordered patients. The Obstructive Sleep Apnea Syndrome (OSA) is attributed to a functional narrowing of the upper airway, particularly of the oropharynx, during sleep. This narrowing is multifactorial. We have shown that in 60% cases, the maxilla (nasal pyramid) seems too narrow. A mandible retroposition may also play a dominant role in 30% of the cases. Both scenarios can be combined. Cone Beam Computed Tomography (CBCT) is a new medical imaging technique that permits to visualize the upper airway with less ionizing radiation than the conventional scanner. To date, only five authors have performed an upper airway's 3D analysis of sleep apnea patients with cone beam. A better understanding of the affected segment of the upper airway should help refine treatment options.
在过去几十年中，医学成像技术的进步使人们对睡眠障碍患者的上气道结构有了更深入的了解。阻塞性睡眠呼吸暂停综合征（OSA）归因于睡眠期间上气道，尤其是口咽部位的功能性狭窄。这种狭窄是多因素导致的。我们已经表明，在60%的病例中，上颌骨（鼻锥体）似乎过于狭窄。下颌后缩在30%的病例中也可能起主要作用。这两种情况可能同时存在。锥形束计算机断层扫描（CBCT）是一种新的医学成像技术，与传统扫描仪相比，它能够以较少的电离辐射显示上气道。迄今为止，只有五位作者使用锥形束对睡眠呼吸暂停患者的上气道进行了三维分析。对上气道受影响节段的更好理解应有助于优化治疗方案。
