在鼻泪管阻塞性疾病中应用CT测量鼻泪道相关解剖参数的研究进展

Advances in CT-based anatomical parameters of nasolacrimal duct in nasolacrimal duct obstructive diseases

鼻泪管阻塞性疾病(NLDOD)是临床发病率较高的一种眼科常见病,是由于炎症或其他原因引起的鼻泪管部分或全部阻塞不通,主要表现为溢泪,继发泪囊炎可出现溢脓,继发泪囊囊肿导致泪囊扩大、内眦肿胀等,开通阻塞的鼻泪管则是治疗鼻泪管阻塞性疾病的关键,明确鼻泪道相关解剖参数在鼻泪管阻塞性疾病的诊断和治疗中显得极为重要。而泪道CT是泪道影像学检查常用方法之一,便于对鼻泪道相关解剖参数进行测量。本文综述近年来在鼻泪管阻塞性疾病中应用CT测量鼻泪道相关解剖参数的研究进展,主要包括鼻泪道及泪囊的经线、面积、体积、角度等,分析总结相关解剖参数与鼻泪管阻塞性疾病的相关性,以便更好地指导临床。

Nasolacrimal duct obstructive disease is a common ophthalmological disease with high clinical incidence.It is caused by inflammation or other reasons that nasolacrimal duct obstruction is partially or totally impassable.The main manifestation is epiphora.Secondary dacryocystitis can cause pyorrhea and secondary dacryocyst cyst can lead to enlargement of lacrimal sacand swelling of inner canthus.Opening obstructive nasolacrimal duct is the key to treat nasolacrimal duct obstructive disease.Tract-related anatomical parameters are very important in the diagnosis and treatment of nasolacrimal duct obstructive diseases.CT is one of the common methods of imaging examination of lacrimal duct,which is convenient for measuring the relevant anatomical parameters of nasolacrimal duct.This article reviews the research progress of CT measurement of nasolacrimal duct related anatomical parameters in nasolacrimal duct obstructive diseases in recent years,including the length and width,area,volume and angle of nasolacrimal duct and lacrimal sac,and summarizes the correlation between related anatomical parameters and nasolacrimal duct obstructive diseases in order to better guide clinical practice.
