Pneumocoeles are uncommon entities, with very few cases reported in the literature. The most plausible aetiological theory is that of a one-way valve effect allowing air into the sinus under increased pressure without pressure equilibration.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215109004411_sec2\"><jats:title>Methods:<\/jats:title><jats:p>Review of a frontal sinus pneumocoele caused by a type III frontal cell and intersinus septal cell.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215109004411_sec3\"><jats:title>Results:<\/jats:title><jats:p>We present a patient with chronic sinusitis who developed a pneumocoele of her left frontal sinus with erosion into her orbit. This patient was a habitual, chronic nose-blower with a large type III frontal cell adjacent to an intersinus septal cell.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215109004411_sec4\"><jats:title>Conclusion:<\/jats:title><jats:p>We propose the new theory that, in our patient, such cells formed a one-way valve, causing air-trapping and pathological expansion of the frontal sinus. To our knowledge, there are no previously published cases that establish an association between large frontal cells and expansion of a pneumocoele.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215109004411","type":"journal-article","created":{"date-parts":[[2009,1,20]],"date-time":"2009-01-20T04:57:01Z","timestamp":1232427421000},"page":"1049-1051","source":"Crossref","is-referenced-by-count":0,"title":["Frontal recess cells: a rare cause of frontal sinus pneumocoele"],"prefix":"10.1017","volume":"123","author":[{"given":"J F","family":"Dixon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B A","family":"Woodworth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,1,20]]},"reference":[{"key":"S0022215109004411_ref4","doi-asserted-by":"publisher","DOI":"10.1258\/0022215021910852"},{"key":"S0022215109004411_ref3","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198705000-00014"},{"key":"S0022215109004411_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(98)70115-9"},{"key":"S0022215109004411_ref6","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.131.3.230"},{"key":"S0022215109004411_ref2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1058970"},{"key":"S0022215109004411_ref1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1987.01860020076016"}],"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\/S0022215109004411","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,30]],"date-time":"2019-04-30T07:54:56Z","timestamp":1556610896000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215109004411\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,1,20]]},"references-count":6,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2009,9]]}},"alternative-id":["S0022215109004411"],"URL":"https:\/\/doi.org\/10.1017\/s0022215109004411","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,1,20]]}}}
