Sialography is used for diagnosis of obstructive salivary gland diseases and prior to sialendoscopy. Three-dimensional cone beam computerized tomography (CBCT) sialography allows imaging and measurement of salivary duct structures. Salivary gland endoscopy has a long learning curve. The aim of this retrospective study is to create an anatomical quantitative guide of different distances and angles significant for endoscopy. Twenty-six CBCT sialographies of healthy parotid ducts were included. Outcome parameters included diameters, distances, angles and number of minor tributaries. Results show the average distance from the papilla to the curvature of the gland was 41.5 mm (Q1 36.97 mm-Q3 45.32 mm), with an angle of 126.9° (Q1 107.58°-Q3 135.6°) of the curvature and a distance of 35.25 mm (±7.81 mm) between the curvature and the hilus. The mean width of the duct was 0.8 mm (Q1 0.7 mm-Q3 1.15 mm) at its narrowest and 2 mm (Q1 1.4 mm-Q3 2.2 mm) at its widest. This is the first anatomical quantitative study of the parotid duct in relation to sialendoscopy.
涎管造影术用于阻塞性涎腺疾病的诊断以及涎腺内镜检查之前。三维锥形束计算机断层扫描（CBCT）涎管造影术可对涎腺导管结构进行成像和测量。涎腺内镜检查的学习曲线较长。这项回顾性研究的目的是创建一份对于内镜检查具有重要意义的不同距离和角度的解剖学定量指南。纳入了26例健康腮腺导管的CBCT涎管造影图像。观察指标包括直径、距离、角度和小分支数量。结果显示，从乳头到腺体弯曲处的平均距离为41.5毫米（第一四分位数36.97毫米 - 第三四分位数45.32毫米），弯曲处的角度为126.9°（第一四分位数107.58° - 第三四分位数135.6°），弯曲处与腺门之间的距离为35.25毫米（±7.81毫米）。导管最窄处的平均宽度为0.8毫米（第一四分位数0.7毫米 - 第三四分位数1.15毫米），最宽处为2毫米（第一四分位数1.4毫米 - 第三四分位数2.2毫米）。这是第一项关于腮腺导管与涎腺内镜检查相关的解剖学定量研究。
