Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15\u201339 years), a middle group (40\u201364 years), and an elderly group (\u226565 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air\u2013bone gap at frequencies of 250 Hz and 500 Hz among the three age groups. \n\n\t\u00a0\n\n\tRESULTS: Although type I tympanoplasty was performed most frequently in all age groups, it was performed significantly less often in the elderly group (p<\/jats:p>","DOI":"10.5152\/iao.2017.3513","type":"journal-article","created":{"date-parts":[[2017,7,18]],"date-time":"2017-07-18T03:22:21Z","timestamp":1500348141000},"page":"176-180","source":"Crossref","is-referenced-by-count":3,"title":["Clinical Characteristics of Chronic Perforated Otitis Media in Different Age Groups"],"prefix":"10.65717","volume":"13","author":[{"given":"Masayo","family":"Hasegawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiro","family":"Shinnabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromi","family":"Kanazawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukiko","family":"Iino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naohiro","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55248","published-online":{"date-parts":[[2019,9,3]]},"container-title":["The Journal of International Advanced Otology"],"original-title":[],"link":[{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/920\/918","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/930\/928","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/930\/928","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T11:36:40Z","timestamp":1769081800000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/view\/930"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9,3]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,9,3]]}},"URL":"https:\/\/doi.org\/10.5152\/iao.2017.3513","relation":{},"ISSN":["2148-3817"],"issn-type":[{"value":"2148-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9,3]]}}}
