传统的助听器可使大多数听力障碍者获得社交听力,但有些病人因先天性外耳道狭窄或闭锁、外耳道或中耳的慢性炎症及乳突根治术后外耳道宽大出现反馈性啸叫等无法使用。这些病人虽可配戴骨导助听器,但需要用弹簧把骨振动器压在耳后皮肤上或把骨振动器装在弹簧眼镜上。由于这些装置不美观,不舒适,且音质差而不易被接受。最近瑞典的两所大学研制了一种新型骨导助昕器。这种装置是利用钛与骨的整合作用即在某些情况下骨不需借助纤维组织便可与钛紧密结合,再把机械振动器接在钛上,机械振动器便可经接在骨上的钛将其
Traditional hearing aids can make most people with hearing disabilities get social hearing, but some patients due to congenital external auditory canal stenosis or atresia, chronic inflammation of the external auditory meatus or middle ear and mastoid surgery large external auditory canal appear feedback whistling can not be used. Although these patients can wear bone-conduction hearing aids, they require spring-loaded bone vibrators on the skin behind the ears or bone vibrators on spring glasses. Because these devices are not beautiful, uncomfortable, and poor sound quality and not easily accepted. Recently, two universities in Sweden developed a new bone conduction aid. This device is the use of titanium and bone integration of the role that in some cases without bone tissue with titanium can be closely linked with the titanium, then the mechanical vibrator connected to titanium, the mechanical vibrator can be connected to the bone The titanium will be it
