To assess the demographic and radiographic features of arrested pneumatization of the sphenoid sinus (APS) and their influence on the confidence of oral and maxillofacial radiologists (OMFRs) in diagnosing APS.
Reports of cone beam computed tomography (CBCT) APS were retrieved, and the demographic and radiographic features were retrospectively analyzed. Five OMFRs assessed the CBCT images and their confidence in diagnosing APS. The OMFRs' experience (years), expertise (skull-base CBCT cases/month) and diagnostic confidence level were analyzed for agreement and associations with demographic or radiographic features.
Of 29 APS cases, 17 (58.6%) were females, and the mean age was 29.9±19 years. Twenty cases (69.0%) presented unilaterally, and 27 (93.1%) involved the sphenoid body. The most common accessory site was the pterygoid process (19, 65.5%). The vidian canal and foramen rotundum were involved in 27 (93.1%) and 17 (58.6%) cases, respectively. Most cases (28, 96.6%) were well-defined, corticated, and showed mixed attenuation. APS diagnostic confidence was higher among the expert OMFRs (72.4%-82.8% vs. 58.6%-62.1%).
Radiographic features differentiating APS from skull-base tumors were shown on CBCT. The confidence of OMFRs with similar experience in years depended on their frequency of examining CBCT cases involving the skull base.
评估蝶窦气化不全（APS）的人口统计学和影像学特征及其对口颌面放射科医生（OMFRs）诊断 APS 的信心的影响。
检索了锥形束 CT（CBCT）APS 的报告，并回顾性分析了人口统计学和影像学特征。五名 OMFR 评估了 CBCT 图像及其诊断 APS 的信心。分析 OMFR 的经验（年）、专业知识（颅底 CBCT 病例/月）与诊断信心水平与人口统计学或影像学特征的一致性和相关性。
在 29 例 APS 病例中，17 例（58.6%）为女性，平均年龄为 29.9±19 岁。20 例（69.0%）为单侧，27 例（93.1%）累及蝶骨体。最常见的副鼻窦是翼突（19，65.5%）。27 例（93.1%）和 17 例（58.6%）分别累及翼管和圆孔。大多数病例（28，96.6%）边界清楚，皮质化，呈混合密度。专家 OMFRs 的 APS 诊断信心较高（72.4%-82.8%比 58.6%-62.1%）。
CBCT 显示了将 APS 与颅底肿瘤区分开来的影像学特征。具有相似年限经验的 OMFRs 的信心取决于他们检查涉及颅底的 CBCT 病例的频率。
