A FDA dos EUA define os implantes cocleares como dispositivos auditivos eletr\u00f3nicos implantados cirurgicamente e que produzem sensa\u00e7\u00f5es auditivas ben\u00e9ficas.

class=\"wp-block-paragraph\">O ouvido externo inclui o pavilh\u00e3o auricular e o canal auditivo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O pavilh\u00e3o auricular recolhe as ondas sonoras e encaminha-as para o t\u00edmpano.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O som passa depois pelo ouvido m\u00e9dio, onde os min\u00fasculos oss\u00edculos auditivos \u2013 martelo, bigorna e estribo \u2013 transmitem e amplificam as vibra\u00e7\u00f5es mec\u00e2nicas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De seguida vem o ouvido interno, onde se encontra <strong>a c\u00f3clea<\/strong> \u2013 uma estrutura em espiral cheia de l\u00edquido.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A c\u00f3clea alberga um sistema complexo de c\u00e9lulas sensoriais, incluindo c\u00e9lulas ciliadas internas e externas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Convertem vibra\u00e7\u00f5es mec\u00e2nicas em sinais nervosos el\u00e9tricos.<\/p>\n\n\n\n<p
