The f&lt;sub&gt;1&lt;\/sub&gt; and f&lt;sub&gt;2&lt;\/sub&gt; levels were delivered at 65 dB SPL. DPOAE amplitudes were compared in 13 patients both before and after mastoidectomy, and between these patients and 5 patients who underwent tympanoplasty.&lt;i&gt; Results:&lt;\/i&gt; The DPOAE amplitudes were significantly decreased at 2 and 4 kHz (p = 0.01 and p = 0.013, respectively) immediately after the mastoidectomy, and still differed from the preoperative results at these frequencies on the first post-mastoidectomy day. After the various individual fluctuations, the DPOAE amplitudes remained decreased in some of the patients at the end of the study. &lt;i&gt;Conclusions:&lt;\/i&gt; Drill-induced noise during mastoidectomy can cause reversible changes in DPOAE in the non-operated ear. OHC function may be diminished during the period after mastoid surgery, and last &gt;1 month.<\/jats:p>","DOI":"10.1159\/000218741","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T17:58:18Z","timestamp":1242410298000},"page":"153-156","source":"Crossref","is-referenced-by-count":13,"title":["Influence of Drilling on the Distortion Product Otoacoustic Emissions in the Non-Operated Ear"],"prefix":"10.1159","volume":"71","author":[{"given":"Lela","family":"Migirov","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Wolf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,5,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3109%2F00016487609120925"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3109%2F00016487909126451"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS0194-5998%2897%2970030-5"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1159%2F000096712"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1017%2FS0022215100110278"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1288%2F00005537-199206000-00016"}],"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/218741","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/218741","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T22:28:07Z","timestamp":1745447287000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000218741"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":6,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2009,7,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000218741","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
