64层螺旋CT上泪囊窝生理值的测量研究

目的:获取泪囊窝各项CT测量数值,分析年龄、性别因素对其的影响,为相关临床工作提供参考。方法:对100例被检者进行64层螺旋CT容积扫描,测量分析泪囊窝各项数据。结果:泪囊窝长度平均为12.28±2.68mm;深度平均为6.56±1.06mm。泪囊窝的内侧壁与鼻腔正中矢状位基本平行。分性别比较,男性泪囊窝较女性略为长、宽;分年龄比较,中老年组泪囊窝各项数值大于青年组。结论:行眶内壁骨折修复术或鼻内镜下鼻腔泪囊造孔术前,应先行64层螺旋CT检查,以明确不同类型泪囊窝骨性构成,预测手术可能遇到的问题,防止手术并发症。

Study on measurement of lacrimal fossa physiological value using 64-slice spiral CT

AIM: To get the CT measurement values oflacrimal fossa, analyze the impact of age, gender factors on it, and provide a reference for relevant clinical work.

METHODS: Totally 100 cases were scanned by 64-slice spiral CT volume. The data of lacrimal fossa was measured and analyzed.

RESULTS:The average length oflacrimal fossa was(12.28±2.68)mm, average depth was(6.56±1.06)mm. The medial wall of the lacrimal fossa and nasal midline sagittal were almost parallel. When the subjects were grouped by gender, the lacrimal fossa of male was a little longer and wider than female's; when the subjects were grouped by age, the data of aged group was bigger than young group's.

CONCLUSION: Before orbital wall fracture repair surgery or endoscopic nasal dacryocyst made holes surgery, we should first check with 64-slice spiral CT to make clear the lacrimal fossa bone of different types construction, to forecast the potential problems during surgery, and how to prevent surgical complications.
