All were assessed before flying by clinical examination and audiology evaluation, followed by post-flight examination to detect barotrauma.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Aircrew members\u2019 ears were divided into 3 groups based on barotrauma and temporal bone pneumatisation: 33 ears with barotrauma and temporal bone pneumatisation of 71 cm\n 3<\/jats:sup>\n or greater (group A); 12 ears with barotrauma and temporal bone pneumatisation of 11.2 cm\n 3<\/jats:sup>\n or lower (group B); and 113 ears with no barotrauma (group C). Mean pneumatisation volumes were 91.05 cm\n 3<\/jats:sup>\n , 5.45 cm\n 3<\/jats:sup>\n and 28.01 cm\n 3<\/jats:sup>\n in groups A, B and C, respectively. A direct relationship was observed between volume of temporal bone pneumatisation of 71 cm\n 3<\/jats:sup>\n or greater and barotrauma grade.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Pneumatisation volume of the mastoid and its communicating air cells that ranges from 11.3 cm\n 3<\/jats:sup>\n to 70.4 cm\n 3<\/jats:sup>\n serves as a reliable predictor of the avoidance of middle-ear barotrauma associated with flying in aircrew members who have normal resting middle-ear pressure and good Eustachian tube function.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1017\/s0022215119002020","type":"journal-article","created":{"date-parts":[[2019,9,27]],"date-time":"2019-09-27T03:30:26Z","timestamp":1569555026000},"page":"918-922","source":"Crossref","is-referenced-by-count":3,"title":["Relation between temporal bone pneumatisation and middle-ear barotrauma in aircrew members"],"prefix":"10.1017","volume":"133","author":[{"given":"A","family":"Hussein","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H M","family":"Abdel Tawab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W T","family":"Lotfi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N","family":"Fayad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N","family":"Elsisy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2019,9,27]]},"reference":[{"key":"S0022215119002020_ref13","doi-asserted-by":"publisher","DOI":"10.1097\/01.MLG.0000165804.09586.B6"},{"key":"S0022215119002020_ref5","first-page":"561","article-title":"Computed tomography of temporal bone pneumatization.
