获得性听力障碍

定义

在生命的某个阶段发生的听力损失，在出生时并不存在。听力障碍在语言习得后持续存在，可能是由于疾病、创伤或药物副作用造成。传导性听力损失可能是由于外耳或中耳的问题，如阻塞（耵聍、异物）、听小骨损坏、中耳感染和/或鼓膜穿孔。感音神经性听力损失是一种类型的听力损失，其根本原因在于前庭神经（第八颅神经）、内耳或大脑中央处理中心。混合型传导性和感音神经性听力损失是指传导性和感音神经性听力损失的混合。

Loss of hearing that occurs sometime the course of life and is not present at birth. The hearing impairment is sustained after the acquisition of language, which can occur due to disease, trauma, or as a side-effect of a medicine. Conductive hearing loss may occur as a result of a problem in the outer or middle ear such as an obstruction (cerumen, foreign body), damage to the ossicles, middle ear infections, and/or perforation of the tympanic membrane. Sensorineural hearing loss is a type of hearing loss in which the root cause lies in the vestibulocochlear nerve (Cranial nerve VIII), the inner ear, or central processing centres of the brain. Mixed conductive and sensorineural hearing loss refers to a mix of both conductive and sensorineural hearing loss.
