Although there are rare cases of deafness of central origin, i.e. involving the brain or the auditory nerve (following a stroke or tumour, for example), the vast majority of deafness is linked to a problem in one or both ears. These are known as peripheral deafnesses. Peripheral deafness is subdivided into two broad categories, depending on the location of the lesion: conductive deafness, when the problem is in the outer or middle ear, and sensorineural deafness, when the problem is in the inner ear. The degree of deafness is assessed by audiometry (tonal by listening to pure tones, and vocal by listening to dissyllabic words), and classified as mild, moderate, profound or total deafness, also known as cophosis. Deafness can be unilateral, bilateral, symmetrical or not, or mixed when it is both conductive and perceptive.<br \/>\nUnilateral deafness is called SSD (single-sided deafness) when it affects one ear with moderate deafness up to cophosis, and a contralateral ear with normal hearing. There are many causes of SSD: sudden deafness, trauma, surgery for acoustic neuroma, meningioma, etc.<br \/>\nSound can be transmitted to the inner ear in two different ways: by air and by bone. The first, called air conduction, uses the outer ear, the eardrum and the middle ear.<\/p>\n\t\n<\/div>[vc_empty_space height=&#8221;40px&#8221;]<div class=\"norebro-slider-sc slider-wrap\">\n\t<div class=\"slider norebro-slider  without-nav\" \n\tid=\"norebro-custom-6a04977098058\" \n\tdata-norebro-slider='{\"loop\":true,\"dots\":true,\"nav\":false,\"autoplay\":true,\"autoplayHoverPause\":true,\"itemsDesktop\":\"2\",\"itemsTablet\":\"1\",\"itemsMobile\":\"1\",\"dotsEach\":\"1\",\"slideBy\":\"1\",\"autoplayTimeout\":\"3\"}' \n\t\t>\n\n\t\t<div class=\"slider-wrap\">\n\n\t[vc_single_image image=&#8221;5677215&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221;]\t\n<\/div><div class=\"slider-wrap\">\n\n\t[vc_single_image image=&#8221;5677216&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;]\t\n<\/div><div class=\"slider-wrap\">\n\n\t[vc_single_image image=&#8221;5677217&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221;]\t\n<\/div>\t\t\n\t<\/div>\n<\/div>[vc_empty_space height=&#8221;20px&#8221;]<div class=\"norebro-text-sc justify\" \n\tid=\"norebro-custom-6a049770a3602\" \n\t \n\t>\n\n\t<p>A bone-anchored prosthesis consists of three parts:<\/p>\n<ul>\n<li>A titanium bone conduction implant osseointegrated into the temporal bone and fitted by the ENT surgeon during surgery.<\/li>\n<li>A titanium abutment attached to the bone conduction implant, onto which the sound processor will be clipped (only 6-8 weeks after surgery).<\/li>\n<li>An external sound processor that clips onto the abutment.
