摘　　要：目的通过鼻泪管CT平扫联合三维重建分析先天性泪囊突出患儿骨性鼻泪管的解剖特征。方法2018年1月至2021年1月就诊于保定市儿童医院眼科12例(12眼)单侧先天性泪囊突出患儿,行鼻泪管CT平扫联合三维重建,测量双侧鼻泪管起始段、中段、末段骨性鼻泪管的横径、前后径,观察分析骨性鼻泪管的解剖特征。双侧起始段、中段、末段骨性鼻泪管横径、前后径分别进行配对t检验。结果鼻泪管CT平扫联合三维重建可清晰显示儿童先天性泪囊突出骨性鼻泪管的解剖特征。患侧骨性鼻泪管起始段横径(5.12±0.96)mm,前后径(6.14±1.01)mm;中段横径(4.35±0.98)mm,前后径(5.62±1.12)mm;末段横径(4.88±0.97)mm,前后径(5.79±1.01)mm;健侧骨性鼻泪管起始段横径(4.18±0.87)mm,前后径(5.34±1.04)mm;中段横径(3.82±0.86)mm,前后径(4.56±1.02)mm;末段横径(4.10±0.93)mm,前后径(4.72±1.00)mm。患侧骨性鼻泪管起始段、中段、末段横径较健侧均扩大(t=3.402、3.891、3.584,P=0.001,0.000,0.001),前后径均扩大(t=3.636、3.356、3.549,P=0.001、0.002、0.001)。结论先天性泪囊突出患侧骨性鼻泪管发育与健侧存在差异,患侧骨性鼻泪管扩张较为明显。Objective To analysis of anatomic characteristics of bony nasolacrimal duct in children with congenital dacryocystorhinocele by CT scan combined with three-dimensional reconstruction.Methods From January 2018 to January2021,12 children(12 eyes)with unilateral congenital dacryocystorhinocele were treated by CT scan combined with three-dimensional reconstruction in the department of ophthalmology of Baoding children’s hospital.The transverse,anteroposterior and anteroposterior diameters of the bilateral nasolacrimal ducts were measured to observe and analyze the anatomical features of bony nasolacrimal duct.The transverse diameter,anteroposterior diameter and anteroposterior diameter of bilateral primary,middle and terminal bony nasolacrimal duct were examined by paired t test.Results CT scan combined with three-dimensional reconstruction of nasolacrimal duct can clearly show the anatomic features of bone nasolacrimal duct in children with congenital dacryocyst protrusion.The diameter of the initial segment(5.12±0.96)mm,the diameter of the anterior and posterior segment(6.14±1.01)mm,the diameter of the middle segment(4.35±0.98)mm,the diameter of the anterior and posterior segment(5.62±1.12)mm,the diameter of the distal segment(4.88±0.97)mm,the diameter of the anterior and posterior segments(5.79±1.01)mm,the diameter of the contralateral nasolacrimal duct was(4.18±0.87)mm in the initial segment,(5.34±1.04)mm in the anterior and posterior segments,(3.82±0.86)mm in the middle segment,(4.56±1.02)mm in the anterior and posterior segments,(4.10±0.93)mm in the distal segment,and(4.72±1.00)mm in the anterior and posterior segments,the transverse diameters of the initial,middle and terminal segments of the affected nasolacrimal duct were all enlarged(t=3.402,3.891,3.584,P=0.001,0.000,0.001),and the anterior and posterior diameters were all enlarged(t=3.636,3.356,3.549,P=0.001,0.002,0.001).Conclusion The development of bony nasolacrimal duct on the affected side of congenital dacryocystitis is different from th
