中文摘要：

目的:探讨鼻内窥镜联合MRI应用对鼻咽癌诊断和临床分期的价值。方法:对200例鼻咽癌患者不同径路鼻内窥镜下鼻咽部活检术及其CT、MRI检查的资料进行对比分析。结果:根据鼻腔宽窄情况选择不同径路鼻内窥镜下鼻咽部活检可以提高活检阳性率。MRI在判断咽旁间隙、颈动脉鞘区、海绵窦侵犯和颅底破坏方面较CT准确。结论:鼻内窥镜与MRI联合应用对鼻咽癌的准确诊断和正确T分期具有重要作用。

Objective: To explore the value of diagnosing and staging nasophryngeal carcinoma examined by nasal endoscope and MRI.Methods:200 cases of NPC patients biopsied by nasal endoscope and examined by CT and MRI were analyzed. Result: The positive rate of nasopharyngeal biopsy by Nasal Endoscope with three different ways according to the volume of nasal cavity was increased. It is more accurate in paranasopharyngeal spaces extension,skull base erosion,vagina carotica and cavernous sinus encroachment examined by ...
