摘要
目的探讨听神经瘤的早期诊断及综合治疗方法。方法回顾分析2002年1月～2003年6月20例听神经瘤的诊断和治疗病例资料。结果吸神经瘤早期临床表现单侧进行性感音神经性听力下降伴耳鸣或突发性耳聋,眩晕、走路不稳感。纯音测听以高频听力下降曲线为主,听性脑干诱发电位(ABR)主要表现I～V波间期延长的蜗后聋。治疗以手术切除为主,乙状窦后经内听道入路(SRT)是主要术式,也可采用伽玛刀手术切除或观察治疗。结论听神经瘤早期临床表现为耳蜗与前庭功能异常。纯音测听高频听力下降曲线和ABR的蜗后聋对诊断听神经瘤具有重要临床价值。治疗以手术切除为主,也可采用伽玛刀手术或观察治疗。
Objective To discuss the diagnosis early and synthetically treatment of acoustic neuroma.Methods A retrospective review was carried out among 20 cases from January 2002 to June 2003,through clinical diagnosis and treatment of acoustic neuroma.Results The earlier performance of acoustic neurema was a side marching sensorineural hearing loss and tinnitus,idiopathic sudden sensorineural bearing loss,verti- go and unbalabce.It was the main curve of high frequency deafness for the acoustic neuroma with Pure-tone test,and retocochlear deafness with ABR.It was the main surgery in cure,the main surgery method was SRT,the other gamma cut and observation.Conclusion The earlier perfor- mance of acoustic neuroma is the abnormal function of cochlea and forecourt.It is the important clinical value for the acoustic neuroma that is the high frequency deafness curve with Pure-tone test,and retmcochlear deafness with ABR.It is the main surgery for the acoustic neuroma is cure, and the other is the gamma cut and the observation.
