听神经瘤占颅内肿瘤的5～10%,占小脑桥脑角肿瘤的80～90%。近年,由于诊断技术的进展,已能对听神经瘤作出早期诊断,因此,手术死亡率及并发症显著减少,同时面神经功能及听力保存率也日益增加。现将听神经瘤的早期诊断近况综述如下。一、临床症状的诊断意义听神经瘤在发病过程中,早期90%以上就诊于耳鼻喉科,但在日常临床上,耳科医师有时忽视了其临床症状的意义,致使许多早期病人延误诊断,应特别予以注意。在临床症状中听力障碍通常是听神经瘤的最早期症状之一,多为单侧,呈进行性加重,有 Acoustic neuroma accounts for 5 to 10% of intracranial tumors, accounting for 80 to 90% of cerebellar pontine tumors. In recent years, due to advances in diagnostic techniques, early diagnosis of acoustic neuroma has been made, therefore, there is a significant reduction in operative mortality and complications, and facial nerve function and hearing preservation rate are also increasing. Now the early diagnosis of acoustic neuroma are summarized below. First, the clinical significance of the diagnosis of acoustic neuroma in the pathogenesis of early 90% of the treatment in ENT, but in clinical practice, otologists sometimes ignore the significance of its clinical symptoms, resulting in many early diagnosis of delayed patients should be Pay special attention. Hearing disorders in clinical symptoms are usually one of the earliest symptoms of acoustic neuroma, mostly unilateral, progressive increase, there
