The hypotympanum average depth was 2 mm (0.44\u20136.40 mm) and the retrotympanum average depth was 1 mm (0\u20132.53 mm).<\/jats:p><\/jats:sec>Conclusion:<\/jats:title>Grooves drilled across the tympanic sulcus should be placed at a point 20 per cent of the height of the tympanic membrane or lower; this will ensure least risk of injury to the chorda tympani nerve. The depth of the hypotympanum and retrotympanum dictates that the posteroinferior part of a subannular tube flange should be approximately 2 \u00d7 1 mm.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215115003072","type":"journal-article","created":{"date-parts":[[2015,11,16]],"date-time":"2015-11-16T04:33:07Z","timestamp":1447648387000},"page":"69-75","source":"Crossref","is-referenced-by-count":3,"title":["Subannular tube insertion: anatomical considerations"],"prefix":"10.1017","volume":"130","author":[{"given":"A K","family":"Guidera","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Benoiton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"McManus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P J D","family":"Dawes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2015,11,16]]},"reference":[{"key":"S0022215115003072_ref12","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200111000-00008"},{"key":"S0022215115003072_ref16","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-012-0941-z"},{"key":"S0022215115003072_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-006-0367-x"},{"key":"S0022215115003072_ref18","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198710000-00004"},{"key":"S0022215115003072_ref13","first-page":"301","article-title":"Long-term treatment of chronic eustachian tube dysfunction by subannular ventilation tubes","volume":"26","author":"Al-Swadi","year":"2005","journal-title":"Otol Neurotol"},{"key":"S0022215115003072_ref15","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2011.197"},{"key":"S0022215115003072_ref14","doi-asserted-by":"publisher","DOI":"10.1258\/0022215042790510"},{"key":"S0022215115003072_ref11","doi-asserted-by":"publisher","DOI":"10.1017\/S002221510013230X"},{"key":"S0022215115003072_ref1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1980.00790260029009"},{"key":"S0022215115003072_ref2","doi-asserted-by":"publisher","DOI":"10.1177\/019459988509300306"},{"key":"S0022215115003072_ref3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2273.2004.00874.x"},{"key":"S0022215115003072_ref4","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2001.113941"},{"key":"S0022215115003072_ref5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2273.1996.tb01106.x"},{"key":"S0022215115003072_ref7","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1968.00760060646018"},{"key":"S0022215115003072_ref8","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1970.00770040471001"},{"key":"S0022215115003072_ref9","doi-asserted-by":"publisher","DOI":"10.1177\/019459989110500523"},{"key":"S0022215115003072_ref10","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215110000897"},{"key":"S0022215115003072_ref17","doi-asserted-by":"publisher","DOI":"10.1055\/s-0029-1214393"},{"key":"S0022215115003072_ref19","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1258\/0022215053561657","article-title":"A study of chorda tympani nerve injury and related symptoms following middle-ear surgery","volume":"119","author":"Goplan","year":"2005","journal-title":"J Laryngol Otol"},{"key":"S0022215115003072_ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2006.12.022"}],"container-title":["The Journal of Laryngology & Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215115003072","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,1]],"date-time":"2019-09-01T11:33:52Z","timestamp":1567337632000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215115003072\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,11,16]]},"references-count":20,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2016,1]]}},"alternative-id":["S0022215115003072"],"URL":"https:\/\/doi.org\/10.1017\/s0022215115003072","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,11,16]]}}}
