多年来听神经瘤的临床表现一直是神经科及耳鼻咽喉科医师感兴趣的话题。 本文研究的目的是:了解当前听神经瘤的诊断进展及评价核磁共振对听神经瘤患者临床表现的意义。资料取自作者所在医院1986～1990年间收治的确诊为听神经瘤的120例病例,其中单侧123例,双侧3例,肿瘤大小分为,小肿瘤(<1cm),占24％,平均年龄54岁。中肿瘤(1～3cm),占60％,平均年龄51岁。大肿瘤(>3cm),占16％,平均年龄43岁。肿瘤大小的平均值为2.1cm(0.3～5.5cm)。 临床表现:1.听力障碍,主诉听力损失者85％。肿瘤愈大,其发生率愈高;肿瘤≥3cm组占95％。出现听力下降则在听神经瘤确诊前3.9年。67％的病人听力障碍为首发症状。听力损失通常是
The clinical presentation of neuroma has been a topic of interest to neurologists and otolaryngologists for many years. The purpose of this study is to understand the current diagnosis of acoustic neuroma and evaluate the clinical significance of magnetic resonance imaging in patients with acoustic neuroma. The data were collected from 120 patients diagnosed as acoustic neuroma admitted to our hospital from 1986 to 1990, including 123 cases of unilateral and 3 cases of bilateral tumors. The tumor size was divided into small tumors (<1cm), accounting for 24%. The average age 54 years old. The tumor (1 ~ 3cm), accounting for 60%, with an average age of 51 years. Large tumors (> 3cm), accounting for 16% with an average age of 43 years. The average tumor size was 2.1 cm (0.3-5.5 cm). Clinical manifestations: 1. Hearing impairment, chief complaint 85% of hearing loss. The larger the tumor, the higher the incidence; tumor ≥ 3cm group accounted for 95%. Appear hearing loss in acoustic neuroma confirmed before 3.9 years. 67% of patients with hearing impairment as the first symptom. Hearing loss is usually
