Abstract

Purpose: To compare the narrowest diameter of the bony nasolacrimal canal (BNLC) in a Chinese population with and without primary acquired nasolacrimal duct obstruction (PANDO).

Methods: Eighty-one patients with PANDO and forty-two non-PANDO patients underwent computed tomography (CT) covering the full length of their nasolacrimal canals. The narrowest transverse diameters of the BNLC were measured in axial CT images.

Results: The narrowest BNLC diameter was significantly shorter in PANDO patients than non-PANDO patients (4.20 ± 0.87 mm vs. 4.95 ± 0.82 mm, p < 0.001), especially in patients aged 40 years and older (4.20 ± 0.84 mm vs. 5.11 ± 0.83 mm, p < 0.001). When males and females were analyzed separately, the differences between PANDO patients and controls remained significant (4.32 ± 0.82 mm vs. 5.70 ± 0.64 mm, p < 0.001, male; 4.18 ± 0.88 mm vs. 4.74 ± 0.75 mm, p < 0.001, female). Generally, in the Chinese population, males have a larger minimum transverse diameter compared to females (5.70 ± 0.64 mm vs. 4.74 ± 0.75 mm, p < 0.001). Furthermore, the narrowest transverse diameter of the BNLC remarkably increased with age (r = 0.432, p < 0.0001).

Conclusions: BNLC stenosis may be an important etiological factor for PANDO in the Chinese population.

有和没有原发性获得性鼻泪管阻塞的最窄骨鼻泪管直径的计算机断层评估：中国人群的比较研究。

目的：比较有和无原发性获得性鼻泪管梗阻（PANDO）的中国人群骨鼻泪管（BNLC）的最窄直径。方法：对81例PANDO患者和42例非PANDO患者进行了鼻泪管全长度的CT扫描。在轴向CT图像上测量BNLC的最窄横向直径。结果：PANDO患者最窄的BNLC直径明显短于非PANDO患者（4.20±0.87 mm vs 4.95±0.82 mm）。结论：BNLC狭窄可能是中国人群PANDO的重要病因。
