面神经鞘瘤误诊原因分析

An analysis of the causes of misdiagnosis on facial neurinoma

目的:对面神经鞘瘤的误诊情况进行总结,探讨提高早期诊断的方法。方法:对4例面神经鞘瘤的临床资料及误诊原因进行分析,并介绍典型病例。结果:面神经鞘瘤早期除面瘫外无其它症状,临床容易造成长时间误诊,多误诊为Bell氏麻痹、慢性中耳炎、中耳肿瘤等,常规听力学检查和普通X线片诊断意义不大,CT或MRI等影像学检查可提高早期诊断率。结论:面神经鞘瘤误诊率高,临床医生对面瘫病人应特别强调CT或MRI等影像学检查的重要性,并应定期随诊复查。

Objective: To investigate the misdiagnosis of facial neurinoma,the clinical data of 4 cases and misdiagnosis causes were analyzed. Method:The clinical data of 4 patients with facial neurinoma were reviewed, the causes of misdagnosis were analyzed, and two typical cases were reported. Results:There was no symptom except facial paralysis at the early time. It was easy to make misdiagnosis for a long time ,such as Bell's paralysis,chronic otitis and middle ear tumours.It was little helpful for diagnosis of routine audiological examine and common X ray photograph. CT scan and MRI would be possible to increase the diagnosis rate. Conclusion:The facial neurinoma is a rare dsease. It had a high misdiagnosis rate. We emphasize that CT scan and MRI should be check up when patient with facial paralysis. And these patients must be follow up and the radializations must be repeated.
