We sought to validate a previously described 4\u2010type grading system for superior turbinate attachment (Type: A, within its medial one\u2010third; B, in its middle one\u2010third; C, to its lateral one\u2010third; and D, directly to the orbit) to the face of the sphenoid sinus and to make recommendations for its use in determining the method of sphenoidotomy (transethmoidal vs transsphenoethmoidal).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>Single\u2010slice images through both sphenoid sinus ostia were obtained from axial series of computed tomography (CT) scans. Eighteen (36 ostia) sets of scans were used. Attachment type (A\u2010D) in each image was classified by 10 experienced sinus surgeons and compared against a \u201cgold standard\u201d grading performed by the senior author (A.J.), who was the developer of the grading system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Mean accuracy was 63% (95% confidence interval [CI], 54%\u201072%) for the 4\u2010type grading system. When Types A+B and Types C+D were grouped together, mean accuracy was 91% (95% CI, 84%\u201097%). For the 2\u2010group classification system, bootstrap analysis suggested that 97% of physicians attain an accuracy of at least 80%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>Accuracy using the 4\u2010type classification is too low to be practically useful. Accuracy using the 2\u2010group system may be sufficiently high to be a useful aid in selecting a surgical approach. We recommend a transethmoid sphenoidotomy for Types A and B and a transsphenoethmoidal approach to the sphenoid for Types C and D. \u00a9 2012 ARS\u2010AAOA, LLC.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21041","type":"journal-article","created":{"date-parts":[[2012,4,5]],"date-time":"2012-04-05T19:03:15Z","timestamp":1333652595000},"page":"411-414","source":"Crossref","is-referenced-by-count":6,"title":["Validation of a grading system for the attachment of the superior turbinate to the sphenoid face"],"prefix":"10.1002","volume":"2","author":[{"given":"Vishnu S.","family":"Sunkaraneni","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hubert","family":"Wong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amin","family":"Javer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,4,5]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(99)70267-6"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2009.23.3249"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2010.04.009"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200207000-00007"}],"container-title":["International Forum of Allergy &amp; Rhinology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21041","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/alr.21041","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T17:53:27Z","timestamp":1698774807000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/alr.21041"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,4,5]]},"references-count":4,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2012,9]]}},"alternative-id":["10.1002\/alr.21041"],"URL":"https:\/\/doi.org\/10.1002\/alr.21041","archive":["Portico"],"relation":{},"ISSN":["2042-6976","2042-6984"],"issn-type":[{"value":"2042-6976","type":"print"},{"value":"2042-6984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,4,5]]}}}
