■本研究的目的是分析CT测量的额骨与骨性鼻泪管交叉角(FB-BNLD)的特征,并为治疗原发性获得性鼻泪管阻塞(PANDO)提供建议。中国西部的患者。
■三百九名参与者,分别,使用RadiAntDICOMViewer进行评估。我们将FB-BNLD角>0°定义为前部型,FB-BNLD角≤0°定义为后部型。
■所有参与者的平均FB-BNLD为-2.52°(95%CI,-3.16°至-1.88°),其中37.2%为前部型,62.8%为后部型。约65.0%的女性患者为后FB-BNLD型,54.2%的男性患者为前FB-BNLD型(p=0.002)。后FB-BNLD是PANDO和对照组的主要类型(p=.011),两组FB-BNLD角度差异有统计学意义(PANDO组,-2.54°至-0.71°;对照组,-4.42°至-2.67°;p<.001)。在男性参与者中,两组的FB-BNLD类型不同(p=.036),FB-BNLD角度的差异(PANDO组,0.59°至5.13°;对照组,-4.08°至1.89°;p=.034)。两组女性参与者的FB-BNLD类型没有差异(p=0.051)。
■本研究揭示了FB-BNLD类型的个体差异,男性前型占多数,女性后型占优势。在CT上评估FB-BNLD类型可以提供一种在计划进行泪道操作期间了解鼻泪管状况的快速方法。
UNASSIGNED: The aim of this study was to analyze the characteristics of CT-measured intersection angle (FB-BNLD) between the frontal bone and bony nasolacrimal duct and to provide suggestions for treating primary acquired nasolacrimal duct obstruction (PANDO) patients in West
China.
UNASSIGNED: Three hundred and nine participants\' CT were, respectively, evaluated with RadiAnt DICOM Viewer. We defined the FB-BNLD angle >0° as the anterior type and the FB-BNLD angle ≤0° as the posterior type.
UNASSIGNED: The mean FB-BNLD was -2.52° (95% CI, -3.16° to -1.88°) across all participants, of whom 37.2% were of the anterior type and 62.8% of the posterior type. Approximately 65.0% of the female patients had a posterior FB-BNLD type, and 54.2% of the male patients had an anterior FB-BNLD type (p = .002). Posterior FB-BNLD was the dominant type in the PANDO and control groups (p = .011), and the angle of FB-BNLD was statistically different in both groups (PANDO group, -2.54° to -0.71°; control group, -4.42° to -2.67°; p < .001). Among the male participants, the type of FB-BNLD differed between the two groups (p = .036), with differences in the angle of FB-BNLD (PANDO group, 0.59° to 5.13°; control group, -4.08° to 1.89°; p = .034). There was no difference in the type of FB-BNLD in female participants between the two groups (p = .051).
UNASSIGNED: The present study revealed individual differences in the type of FB-BNLD, with anterior-type majority in males and posterior-type dominance in females. Evaluating the FB-BNLD type on CT can provide a fast method for knowing the nasolacrimal duct condition during planning for lacrimal manipulation.
