The objective of this study was to compare the incidental radiographic findings in the maxillofacial structures and the pharyngeal airway between subjects with moderate/severe obstructive sleep apnea (OSA) and mild OSA/healthy subjects using cone-beam computed tomography (CBCT) scans.
A total of 53 subjects with moderate/severe OSA (with a Respiratory Disturbance Index [RDI] ≥ 15 events/h) and 33 mild OSA/healthy subjects (RDI < 15), based on ambulatory somnographic assessment, were recruited. Supine CBCTs were taken and sent for radiological report. The incidental findings were compared between the 2 groups.
Moderate/severe subjects had larger prevalence of conchae bullosa, hypertrophic turbinates, hypertrophic tonsils, elongated or posteriorly placed soft palate, narrower airway, enlarged tongue, and focal calcifications, although no significant differences were found.
CBCT is useful in identifying maxillofacial and airway anomalies that could interfere with normal breathing; however, no significant difference was found in prevalence of incidental findings between subjects with moderate/severe OSA and mild OSA/healthy subjects. Further studies are necessary to generalize our results.
本研究旨在通过锥形束计算机断层扫描（CBCT）比较中重度阻塞性睡眠呼吸暂停（OSA）患者与轻度 OSA/健康受试者的颌面结构和咽气道的偶然放射学发现。
共招募 53 名中重度 OSA 患者（呼吸暂停低通气指数[RDI]≥15 次/小时）和 33 名轻度 OSA/健康受试者（RDI<15）。对仰卧位 CBCT 进行拍摄，并发送进行放射学报告。比较两组之间的偶然发现。
中重度组鼻甲肥大、鼻甲肥大、扁桃体肥大、软腭伸长或后位、气道狭窄、舌体增大和局灶性钙化的发生率较高，但无显著差异。
CBCT 可用于识别可能影响正常呼吸的颌面和气道异常；然而，中重度 OSA 患者与轻度 OSA/健康受试者的偶然发现发生率无显著差异。需要进一步的研究来推广我们的结果。
