We review the pathophysiology of \u201cspeech hyper\u2010resonance syndromes\u201d, and possible mechanisms, including resonances in the tympanic membrane, Eustachian tube and nasopharynx. Treatment can be directed at the eardrum or the ET depending on site of pathology. We review typical presentations, examination findings, and useful clinical tests to distinguish PET from other disorders, and our philosophy of management.<\/jats:p>","DOI":"10.1016\/j.wjorl.2019.08.003","type":"journal-article","created":{"date-parts":[[2019,10,11]],"date-time":"2019-10-11T17:59:02Z","timestamp":1570816742000},"page":"137-142","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":34,"title":["Patulous Eustachian tube (PET), a practical overview"],"prefix":"10.1002","volume":"5","author":[{"given":"Manohar","family":"Bance","sequence":"first","affiliation":[{"name":"Cambridge Ear Institute Cambridge University Hospitals Trust Cambridge UK"},{"name":"University of Cambridge Cambridge UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James R.","family":"Tysome","sequence":"additional","affiliation":[{"name":"Cambridge Ear Institute Cambridge University Hospitals Trust Cambridge UK"},{"name":"University of Cambridge Cambridge UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew E.","family":"Smith","sequence":"additional","affiliation":[{"name":"Cambridge Ear Institute Cambridge University Hospitals Trust Cambridge UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,9]]},"reference":[{"issue":"4","key":"e_1_2_3_2_1","first-page":"151","article-title":"Occlusion effect in bone conduction pure tone and speech audiometry","volume":"2","author":"Edgerton B.J.","year":"1977","journal-title":"J Am Audiol Soc"},{"key":"e_1_2_3_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e31819d895e"},{"key":"e_1_2_3_4_1","first-page":"259","article-title":"Simple mass loading of the tympanic membrane to alleviate symptoms of patulous eustachian tube","volume":"39","author":"Bartlett C.","year":"2010","journal-title":"J Otolaryngol Head Neck Surg"},{"key":"e_1_2_3_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000320"},{"key":"e_1_2_3_6_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016487809124763"},{"key":"e_1_2_3_7_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016489.2013.808763"},{"key":"e_1_2_3_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e3182184e23"},{"key":"e_1_2_3_9_1","first-page":"242","article-title":"Sniff\u2010induced negative pressure\u2014a cause for the development of middle ear diseases?","volume":"37","author":"Hauser R.","year":"1989","journal-title":"HNO"},{"key":"e_1_2_3_10_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0206946"},{"key":"e_1_2_3_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.27443"},{"key":"e_1_2_3_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.moo.0000176465.68128.45"},{"key":"e_1_2_3_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40463-018-0290-y"},{"key":"e_1_2_3_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016480410016306"},{"key":"e_1_2_3_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mao.0000226301.21080.1c"},{"key":"e_1_2_3_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000696"},{"key":"e_1_2_3_17_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40463-016-0151-5"},{"key":"e_1_2_3_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001130"},{"key":"e_1_2_3_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000900"},{"key":"e_1_2_3_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.25168"},{"key":"e_1_2_3_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-016-4022-5"},{"key":"e_1_2_3_22_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198101000-00023"},{"key":"e_1_2_3_23_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2016.1231420"}],"container-title":["World Journal of Otorhinolaryngology -
