摘要

摘要: 目的:对鼻内泪囊鼻腔造口术相关结构的冠状切面进行断层解剖研究,为临床提供解剖学依据。方法:提取创建的头部冠状切面图像数据集中含泪囊和鼻泪管结构的图像,对左侧泪囊、鼻泪管及毗邻结构的形态、空间相互位置关系进行连续断层解剖学观察,对重要部位微细结构断面进行测量。结果:不同断面的图像可以精准呈现泪囊、鼻泪管和其毗邻结构的原位形态及相互位置关系。泪囊内侧壁最薄1.2 mm,外侧壁最薄0.6 mm,外侧壁内腔面有一高度为2.3 mm的纵行皱襞。膜性鼻泪管内侧壁厚(1.97±0.47) mm,外侧壁厚 (1.52±0.17) mm,膜性管腔横径(1.78±0.12) mm;骨性鼻泪管内侧壁最薄处0.30 mm,外侧壁最薄处0.15 mm,骨性管腔横径(5.50±0.12) mm;膜性管腔截面积与骨性管腔截面积之比为(13.5±2.9)%。结论:高精度冠状位头部切面图像数据集可用于泪囊、鼻泪管及毗邻结构的断层解剖学研究,可用于微细结构的断面解剖学测量。

Abstract: Objective: To study coronal plane of dacryocystorhinostomy related structures for clinical practice. Method: Extracted images concluding lacrimal sac and nasolacrimal canal information from head coronal sectional imaging data-set we created. Observed shape and location of the left lacrimal sac, nasolacrimal canal, and surrounding structures. Measured details of the important portion. Result: Images of different layer show the shape and locative relationship of the lacrimal sac, nasolacrimal canal, and surrounding structures precisely. The thinnest thickness of medial wall and lateral wall of the lacrimal sac is 1.2 mm and 0.6 mm. There is a 2.3 mm high longitudinal fold on the lateral wall. The thickness of medial wall and lateral wall of membranous nasolacrimal canal is(1.97±0.47) mm and(1.52±0.17) mm. Transverse diameter of membranous nasolacrimal canal is(1.78±0.12) mm. The thinnest thickness of medial wall and lateral wall of bony nasolacrimal canal is 0.30 mm and 0.15 mm. Transverse diameter of bony nasolacrimal canal is(5.50±0.12) mm. The proportion of cross-membranous nasolacrimal canal sectional area in bony nasolacrimal canal sectional area is(13.5±2.9)%. Conclusion: Head coronal sectional imaging data-set with high precision can be used for sectional anatomical study of the lacrimal sac, nasolacrimal canal and surrounding structures and measurement of details.
