Otoacoustic Emissions II. EOAE after Otological Operations. Effect of the Middle Ear Condition and Postoperative Changes on Otoacoustic Emissions
Otoakustické emise II. EOAE po otologických operacích
Klinické využití otoakustických emisí jako indikátoru kochleární funkce je do značné míry omezeno závislostí na stavu středouší. Dobrá transdukční funkce středního ucha je nezbytnou podmínkou pro detekovatelnost otoakustických emisí v zevním zvukovodu. Autoři se rozhodli vyhodnotit nálezy otoakustických emisí u 60 uší (52 osob) po různých typech ušních operací. Podmínkou zařazení do studie byl práh vzdušného vedení na frekvencích 0,5 - 4,0 kHz
Klíčová slova:
otoakustické emise, vliv středouší, tympanoplastiky, převodní nedoslýchavost.

Overview
The clinical application of otoacoustic emissions as an indicator of cochlear function is limited to a considerable extent by the state of the middle ear. Adequate transduction function of the middle ear is an essential prerequisite for detection of otoacoustic emissions in the external auditory meatus. The authors decided to evaluate otoacustic emissions in 60 ears (52 subjects) after various types of ear surgery. The condition for inclusion in the investigation was a threshold of air conduction at frequencies of 0.5 - 4.0 kHz
Key words:
otoacoustic emissions, influence of middle ear, tympanoplasty, conductive deafness.
