Abstract：
UNASSIGNED: The dacryoendoscope is a practical instrument for the examination and the treatment of lacrimal duct obstruction. Nevertheless, as it is a rigid fiberscope, manipulation of the endoscope is somewhat affected by the patient\'s lacrimal duct alignment and the skeletal structure of the face. The morphology and inclination of the lacrimal duct vary among individuals and ethnic groups. We aimed to evaluate the alignment of the lacrimal duct from the perspective of endoscopic maneuverability in a Japanese population.
UNASSIGNED: This retrospective study analyzed the cone-beam computed tomography dacryocystography (CBCT-DCG) images of 102 patients diagnosed with unilateral primary acquired nasolacrimal duct obstruction (PANDO) at Ehime University Hospital from December 2015 to May 2021. The following parameters of the lacrimal duct on the contralateral side of unilateral PANDO were investigated: (1) angle formed by the superior orbital rim-internal common punctum-nasolacrimal duct opening, (2) angle formed by the lacrimal sac and the nasolacrimal duct, (3) length of the lacrimal sac, and (4) length of the nasolacrimal duct.
UNASSIGNED: Measurements of the above parameters were (1) 10.2° ± 7.8° (range, -11° to +27°), (2) -6.3° ± 14.1° (range, -43° to +40°), (3) 8.9 ± 2.3 mm (range, 4.3-17.1), and (4) 13.2 ± 2.7 mm (range, 5.7-20.7), respectively. The Shapiro-Wilk test demonstrated that the values of all parameters, except (3), followed a normal distribution (p = 0.55, 0.30, 0.0002, and 0.39, respectively). No significant difference was found between the female and male groups (p > 0.05).
UNASSIGNED: This study reported anthropometric analysis data of the morphology of the lacrimal ducts using CBCT-DCG in a Japanese population. In our cohort, the line from the superior orbital rim through the internal common punctum to the nasolacrimal duct opening inclined anteriorly in 92% of the patients.

摘要：
■泪镜是一种用于检查和治疗泪管阻塞的实用仪器。然而，因为它是一个刚性纤维镜，内窥镜的操作在一定程度上受到患者的泪管排列和面部骨骼结构的影响。泪管的形态和倾斜度因个体和种族而异。我们旨在从日本人群的内窥镜可操作性的角度评估泪管的排列。
这项回顾性研究分析了2015年12月至2021年5月在爱媛大学医院诊断为单侧原发性获得性鼻泪管阻塞（PANDO）的102例患者的锥形束计算机断层扫描泪囊造影（CBCT-DCG）图像。研究了单侧PANDO对侧泪管的以下参数：（1）由眶上缘-内部共同泪点-鼻泪管开口形成的角度，（2）泪囊与鼻泪管形成的角度，（3）泪囊的长度，和(4)鼻泪管的长度。
■上述参数的测量结果为（1）10.2°±7.8°（范围，-11°至+27°),(2)-6.3°±14.1°(范围,-43°至+40°),(3)8.9±2.3mm(范围,4.3-17.1),和（4）13.2±2.7mm（范围，5.7-20.7),分别。Shapiro-Wilk测试表明，所有参数的值，除了（3），服从正态分布（p分别为0.55、0.30、0.0002和0.39）。女性组和男性组之间无显著差异(p>0.05)。
■本研究报告了在日本人群中使用CBCT-DCG的泪管形态的人体测量分析数据。在我们的队列中，92％的患者从眶上缘通过内部总泪点到鼻泪管开口的线向前倾斜。
