突发性聋可由很多原因引起,如大脑疾患、肿瘤、梅毒、糖尿病、骨折、减压病、血管痉挛或病毒性感染等。经详细检查后,仍有25％以上的病例被诊断为原发性突发性聋(Morrison 1975)。原发性突发性聋的治疗方法有:休息、低盐饮食、解痉药物、星状神经节封闭、静脉输入硫酸组织胺、低分子右旋醣酐、抗凝疗法、口服血管扩张剂或皮质激素。疗法之多说明原发性突发性聋的病因及治疗方法仍属不明。Morrison将原发性突发性聋分为三型:感觉性聋、神经性聋和外周性感觉神经性聋。本文仅涉及神经性或耳 Sudden deafness can be caused by many causes, such as brain disorders, tumors, syphilis, diabetes, fractures, decompression sickness, vasospasm, or viral infections. After careful examination, more than 25% of cases are still diagnosed with primary sudden deafness (Morrison 1975). Treatment of primary sudden deafness: rest, low-salt diet, antispasmodic drugs, stellate ganglion closure, intravenous histamine sulfate, low molecular weight dextran, anticoagulant therapy, oral vasodilators or Corticosteroids. Much of the treatment shows the etiology and treatment of primary sudden deafness is still unknown. Morrison classifies primary sudden deafness into three types: sensory deafness, deafness and peripheral sensory deafness. This article deals only with nerves or ears
