Twenty-four healthy adults, 12 smokers and 12 nonsmokers in the 20\u201330 years age range were selected based on self-reported\n histories of five to eight years of smoking or no smoking, respectively. All subjects received tympanometric screening to rule out middle ear pathology. Conventional (0.25\u20138 kHz) and ultra high frequency (UHF; 10\u201320 kHz) audiometry showed normal or age-appropriate thresholds across\n both groups. DPOAE results showed small, but significant, decline in DPOAE levels without concomitant changes in noise floors in smokers as compared to nonsmokers. I\/O detection thresholds were also significantly elevated at high frequencies in smokers as compared to their nonsmoking counterparts.\n These findings indicate that smokers are at greater risk for cochlear damage than nonsmokers, and that DPOAE amplitudes and I\/O detection thresholds may identify early changes in cochlear function in smokers. Este estudio midi\u00f3 las emisiones otoac\u00fasticas por productos de distorsi\u00f3n\n (DPOAES) y las curvas de ingreso\/salida (I\/O) de las DPOAE para evaluar los efectos del fumado sobre la funci\u00f3n coclear. Veinticuatro adultos, 12 fumadores y 12 no fumadores, en el rango de edad de 20 a 30 a\u00f1os, fueron seleccionados con base en sus historia auto-reportadas de\n fumado o no fumado en los \u00faltimos 5\u20138 a\u00f1os, respectivamente. Todos los sujetos se sometieron a un tamizaje timpanom\u00e9trico para descartar patolog\u00eda del o\u00eddo medio. La audiometr\u00eda convencional (0.25\u20138 kHz) y la de ultra-alta frecuencia (UHF,\n 10\u201320 kHz) mostraron umbrales normales o apropiados para la edad en ambos grupos. Los resultados de las DPOAE mostraron una ca\u00edda peque\u00f1a pero significativa en los niveles de las DPOAE en los fumadores comparado con los no fumadores, sin cambios concomitantes en el piso\n de ruido. Los umbrales I\/O de detecci\u00f3n tambi\u00e9n estuvieron significativamente elevados en las altas frecuencias en los fumadores, comparado con sus contrapartes no fumadores. Estos hallazgos indican que los fumadores tienen un mayor riesgo de da\u00f1o coclear que los no fumadores,\n y que las amplitudes de las DPOAE y los umbrales I\/O de detecci\u00f3n pueden identificar cambios tempranos en la funci\u00f3n coclear de los fumadores.<\/jats:p>","DOI":"10.3766\/jaaa.18.8.4","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"665-674","source":"Crossref","is-referenced-by-count":17,"title":["Effects of Cigarette Smoking on Distortion Product Otoacoustic Emissions"],"prefix":"10.3766","volume":"18","author":[{"given":"Candice","family":"Negley","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bharti","family":"Katbamna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Crumpton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary D.","family":"Lawson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2007\/00000018\/00000008\/art00004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:16:04Z","timestamp":1738797364000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.18.8.4"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,9,1]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2007,9,1]]}},"alternative-id":["1050-0545(20070901)18:8L.665;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.18.8.4","relation":{},"ISSN":["1050-0545"],"issn-type":[{"type":"print","value":"1050-0545"}],"subject":[],"published":{"date-parts":[[2007,9,1]]}}}
