摘要
目的探讨听神经病的临床发病特点。方法对63例听神经病患者的发病年龄、性别、地域分布及纯音听力损失情况进行分析。结果本组63例听神经病中双侧发病占95.24%(6063),单侧发病占4.76%(363)。11～20岁发病率为77.77%(4963)。女性占71.43%(4563),男性占28.57%(1863)。该病呈散在发病,但农村患者占88.89%(5663)。听力损失程度以轻、中度为主,男女间听力损失程度无显著性差异(P>0.05)。上升型和匙型纯音听阈(PTT)图的耳数占60.83%(73120)。镫骨肌声反射(AR)引出率为21.95%。言语识别率为9.94±11.89%.听性脑干反应(ABR)引不出或严重异常。畸变产物耳声发射(DPOAE)正常或基本正常。结论听神经病多见于青少年。女性、农村患者高发。主要为双侧耳发病,听力损失程度呈轻、中度,以低频听力损失为主。
Objective To explore the clinical signs of auditory neuropathy.Methods Feature of primary onset age, sex, areas as well as pure tone audiometry were analysed in 63 patients with auditory neuropathy.Results In 63 cases, bilateral ears were affected in 95.24%(60/63)cases, unilateral ear was affected in 4.76%(3/63)cases. Incidence from 11 to 20 years was 77.77% (49/63 cases). Female male and patients were 71.43% (45/63),28.57% (18/63)respectively.The patients from rural areas were 88.89% (56/63). Pure tone audiometry revealed mainly mild and moderate hearing loss.There was no significant difference in hearing loss degree between male and female patients(P>0.05). Upward-sloping and spoon audiogram were 60.83% (73/120 ears). Inducing rate of acoustic reflex(AR) was 21.95%.Speech discrimination scores(SDS) were 9.94±11.89%. Auditory brainstem response(ABR) was absent or severely abnormal.Distortion product otoacoustic emission(DPOAE) was normal or roughly normal.Conclusion Patients with auditory neuropathy were predominantely juveniles. Incidence of female cases and cases from rural areas were higher. Pure tone audiometry showed mainly bilateral mild and moderate hearing loss at low-frequencies.
