作者回顾了听神经瘤的诊断及治疗史,认为近20年来,随CT、RMI的出现,可诊断直径小于0.75cm及内听道内的听神经瘤。故使手术能彻底切除肿瘤,绝少有死亡及并发症,并保存听力及面神经功能。本文总结了80年5月到87年2月25例听神经瘤经耳鼻喉科及神经外科联合手术的病人,男15例,女10例,平均年龄48岁。随访2个月到6年。术前症状:100％病人有听力下降,56％有耳鸣,44％有头晕或共济失调,16％有真性眩晕;听力下降平均为51个月,其中64％病人>2年,24％病人>5年以上。查体:63％病人Romberg’s征阳性;28％有角膜反射减弱,28％有面部麻木感。
The author reviewed the history of the diagnosis and treatment of acoustic neuromas. It is believed that with the appearance of CT and RMI in the past 20 years, acoustic neuromas with a diameter of less than 0.75 cm and within the auditory canal were diagnosed. Therefore, the operation can completely remove the tumor, with few deaths and complications, and preserve hearing and facial nerve function. This article summarizes the 25 cases of acoustic neuroma from May 1980 to February of 2007 through ENT surgery and neurosurgery combined with 15 males and 10 females with an average age of 48 years. Follow-up from 2 months to 6 years. Preoperative Symptoms: 100% of patients have hearing loss, 56% have tinnitus, 44% have dizziness or ataxia, 16% have true vertigo; hearing loss averages 51 months, 64% of patients> 2 years, 24% of patients >5 years or more. Physical examination: 63% of patients had a positive Romberg’s sign; 28% had weakened corneal reflexes and 28% had facial numbness.
