The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile.<\/jats:p><jats:p>\n            Objective\u2003The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal.<\/jats:p><jats:p>\n            Method\u2003The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500\u2009Hz and 2000\u2009Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal.<\/jats:p><jats:p>\n            Results\u2003The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500\u2009Hz and 2000\u2009Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons.<\/jats:p><jats:p>\n            Conclusion\u2003The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.<\/jats:p>","DOI":"10.1055\/s-0037-1598243","type":"journal-article","created":{"date-parts":[[2017,2,13]],"date-time":"2017-02-13T23:54:42Z","timestamp":1487030082000},"page":"318-322","source":"Crossref","is-referenced-by-count":5,"title":["Air and Bone Conduction Frequency-specific Auditory Brainstem Response in Children with Agenesis of the External Auditory Canal"],"prefix":"10.1055","volume":"21","author":[{"given":"Pricila","family":"Sleifer","sequence":"additional","affiliation":[{"name":"Department of Human Health and Communication, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dayane","family":"Didon\u00e9","sequence":"additional","affiliation":[{"name":"Child and Adolescent Health Program, Universidade Federal do Rio Grande do Sul Ringgold Standard Institution, Porto Alegre, Rio Grande do Sul, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00cdsis","family":"Keppeler","sequence":"additional","affiliation":[{"name":"Department of Human Health and Communication, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudine","family":"Bueno","sequence":"additional","affiliation":[{"name":"Department of Human Health and Communication, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rudimar","family":"Riesgo","sequence":"additional","affiliation":[{"name":"Child Neurology Unit (HCPA-UFRGS), Porto Alegre, Rio Grande do Sul, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,2,13]]},"container-title":["International Archives of Otorhinolaryngology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0037-1598243.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T19:31:03Z","timestamp":1557171063000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0037-1598243"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,2,13]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2017,10,5]]},"published-print":{"date-parts":[[2017,10]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0037-1598243","relation":{},"ISSN":["1809-9777","1809-4864"],"issn-type":[{"value":"1809-9777","type":"print"},{"value":"1809-4864","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,2,13]]}}}
