目的 探讨外伤性泪囊炎CT造影多平面重组的检查方法,研究外伤性泪囊炎CT造影的特点。方法 采用泪道CT碘化油造影多平面重组的方法,分析40例外伤性泪囊炎的CT检查和结果。结果 泪道CT良好地显示了泪囊的大小、泪囊与鼻泪管的关系、泪道阻塞的部位及其周围组织的情况,其中诊断泪囊向外向前移位19例,泪囊向后移位2例,泪囊扩大3例,泪囊萎缩5例。骨性鼻泪管骨折20例,骨性鼻泪管重度狭窄5例,鼻泪管上段阻塞10例。伴有面部骨折情况36例,伴有鼻部病变8例。结论 外伤性泪囊炎CT造影表现复杂多样,泪道CT造影多平面重组能较清晰地显示泪道外伤及其周围组织的情况,可用于指导手术。
Abstract
Objective To study the examination method of multiplanar reconstruction CT with dacryocystography in traumatic dacryocystitis,and the characteristics of CT imaging with dacryocystography in traumatic dacryocystitis. Methods Multiplanar reconstruction CT with iodinated oil injection dacryocystography were used,and the results in 40 patients with traumatic dacryocystitis were analysed. Results The examination well showed the sizes of lacrimal sacs ,the relationship of the lacrimal sacs and nasolacrimal ducts,the position of the obstruction of lacrimal passage, and the injuries of the tissues around lacrimal ducts .The lacrimal sacs were displaced to forward and outside in 19 patients, the lacrimal sacs were displaced to the behind in 2 patiens. the sacs were expanded in 3 cases, the sacs were analosised in 5 cases,the nasolacrimal canal were fractured in 20 patients, stenosis of the nasolacrimal canal was found in 5 patients, the superior segments of the nasolacrimal canal were obstructed in 10 patients.36 patients had fractures of facial bone, and 8 patients had lesion of the nasal part. Conclusions The images of CT with dacryocystography in traumatic dacryocystitis were complicated and multiplex. Multiplanar reconstruction CT with lacrimal dacryocystography in traumatic dacryocystitis can clearly manifest the trauma of lacrimal passage and the injuries of the tissues around it.This method can be used to provide guidance for the operation.
