: This study aimed: (1) to assess the localization of the anatomic landmarks of the pharyngeal airway on cone beam computed tomography (CBCT) images; and (2) to evaluate if resolution of myofascial pain syndrome (MPS) changed the airway dimensions.: Twenty-nine patients with pre- and post-treatment CBCT scans were randomly selected to locate five landmarks twice, with a two-week interval. The same landmarks were used to measure the airway volume and minimal cross-sectional area (CSA).: The intra-observer reliability (ICC) was 0.99-1.00 for volumetric and CSA measurements, based on the five landmarks used. The paired test showed no significant difference in the airway volume ( = 0.68) and CSA ( = 0.96).: The outcomes showed that the landmarks used had excellent ICCs for the volumetric and CSA measurements. There was no change in volume and CSA of the pharyngeal airway after resolution of MPS.
: 本研究旨在：（1）评估咽气道解剖标志在锥形束 CT（CBCT）图像上的定位；（2）评估肌筋膜疼痛综合征（MPS）的缓解是否改变气道尺寸。：随机选择 29 名具有治疗前后 CBCT 扫描的患者，两次定位五个标志，间隔两周。使用相同的标志来测量气道容积和最小横截面积（CSA）。：基于使用的五个标志，容积和 CSA 测量的观察者内可靠性（ICC）为 0.99-1.00。配对检验显示气道容积（ = 0.68）和 CSA（ = 0.96）无显著差异。：结果表明，用于测量容积和 CSA 的标志具有出色的 ICC。MPS 缓解后，咽气道的容积和 CSA 没有变化。
