In the cadaveric studies, the mid-cartilaginous section of the ET presented a curved slit-like lumen. It is believed that this section functions principally as a valve mechanism and acts like an active sphincter of the ET. This report illustrates the dynamic movement of the valve section in a living ET which can be observed by using a superfine fibreoptic videomicroendoscope. Disorders of the open-close mechanism of the valve section in a diseased ET due to different aetiologies are also discussed. This study indicated that transtympanic ET microendoscopy had considerable potential for exploring fascinating new aspects of the physiology, pathophysiology and anatomy dynamics of the ET.<\/jats:p>","DOI":"10.1017\/s0022215100130531","type":"journal-article","created":{"date-parts":[[2007,11,30]],"date-time":"2007-11-30T10:15:14Z","timestamp":1196417714000},"page":"486-490","source":"Crossref","is-referenced-by-count":10,"title":["Valve section of the eustachian tube"],"prefix":"10.1017","volume":"109","author":[{"given":"Chih-Ying","family":"Su","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,6,29]]},"reference":[{"key":"S0022215100130531_ref001","doi-asserted-by":"publisher","DOI":"10.1016\/0091-6749(83)90027-1"},{"key":"S0022215100130531_ref007","doi-asserted-by":"publisher","DOI":"10.1055\/s-0028-1098302"},{"key":"S0022215100130531_ref002","first-page":"15","article-title":"Endoscope de la trompe d'eustache; Premier bilan","volume":"107","author":"Bremond","year":"1990","journal-title":"Annals of Oto-Laryngology"},{"key":"S0022215100130531_ref003","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1973.00780020137016"},{"key":"S0022215100130531_ref009","first-page":"119","article-title":"The nasopharyngeal orifice of the auditory tube: implications for tubal dynamics anatomy","volume":"19","author":"Rood","year":"1982","journal-title":"Cleft Palate Journal"},{"key":"S0022215100130531_ref011","first-page":"311","article-title":"Localization of function in the eustachian tube: a hypothesis","volume":"103","author":"Sando","year":"1994","journal-title":"Annals of Otology, Rhinology and Laryngology"},{"key":"S0022215100130531_ref016","doi-asserted-by":"publisher","DOI":"10.1159\/000414110"},{"key":"S0022215100130531_ref012","first-page":"45","article-title":"Pathology of the eustachian tube","volume":"86","author":"Schuknecht","year":"1967","journal-title":"Archives of Otolaryngology"},{"key":"S0022215100130531_ref015","doi-asserted-by":"publisher","DOI":"10.1177\/000348948609500121"},{"key":"S0022215100130531_ref014","first-page":"521","article-title":"Transtympanic microendoscopic findings of the eustachian tube in patients with nasopharyngeal carcinoma","volume":"16","author":"Su","year":"1994","journal-title":"Head and Neck"},{"key":"S0022215100130531_ref013","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199306000-00017"},{"key":"S0022215100130531_ref008","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1973.00780010006002"},{"key":"S0022215100130531_ref006","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-998060"},{"key":"S0022215100130531_ref005","first-page":"50","article-title":"Microfibreoptic evaluation of the middle ear cavity","volume":"15","author":"Edelstein","year":"1994","journal-title":"American Journal of Otology"},{"key":"S0022215100130531_ref010","doi-asserted-by":"publisher","DOI":"10.1177\/000348948909800812"},{"key":"S0022215100130531_ref004","doi-asserted-by":"publisher","DOI":"10.1177\/00034894800890S312"}],"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215100130531","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,13]],"date-time":"2019-05-13T21:53:43Z","timestamp":1557784423000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215100130531\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1995,6]]},"references-count":16,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1995,6]]}},"alternative-id":["S0022215100130531"],"URL":"https:\/\/doi.org\/10.1017\/s0022215100130531","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[1995,6]]}}}
