Endoscopic examination failed to detect involvement of the pyriform sinus apex in one patient, and considerably underestimated disease at this level in two others; CT accurately predicted the status of the apex in these three and all other patients. Endoscopy underestimated the inferior extent of tumor in six patients; CT revealed the inferior limit relative to the esophageal verge more accurately in all six of these submucosal extensions. Endoscopy revealed one case of mucosal spread to the esophageal verge not demonstrated by CT. Endoscopy and CT were both correct in revealing the esophageal verge to be involved (one case) and free of disease (two cases). This study also confirmed a common tendency of pyriform fossa cancer to spread through thyrohyoid membrane adjacent to the course of superior laryngeal neurovascular bundle (six cases). High\u2010resolution CT, in experienced hands, is a useful adjunct to endoscopy for detecting submucosal, inferior extension of pyriform sinus carcinoma. This information can influence the choice of the lower margin of resection and method of pharyngeal reconstruction.<\/jats:p>","DOI":"10.1002\/hed.2880150110","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T21:46:17Z","timestamp":1172094377000},"page":"44-52","source":"Crossref","is-referenced-by-count":18,"title":["Relative roles of computed tomography and endoscopy for determining the inferior extent of pyriform sinus carcinoma: Correlative histopathologic study"],"prefix":"10.1002","volume":"15","author":[{"given":"Ezzat M.","family":"Saleh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony A.","family":"Mancuso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott P.","family":"Stringer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,7,18]]},"reference":[{"key":"e_1_2_1_2_2","volume-title":"Laryngeal cancer","author":"Mancuso AA","year":"1991"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-199001000-00011"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348948809700508"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-998607"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1989.01860290071017"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.158.3.3945748"},{"key":"e_1_2_1_8_2","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-642-71100-8","volume-title":"Tumors of the larynx: histopathological and clinical interface","author":"Burkhardt Meyer\u2010Breiting","year":"1988"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.141.2.7291568"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.2890100103"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1984.00800360036008"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198103000-00015"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1987.01860050037010"},{"key":"e_1_2_1_14_2","doi-asserted-by":"crossref","first-page":"614","DOI":"10.1288\/00005537-198906000-00009","article-title":"Hypopharyngeal reconstruction: a comparison of two alternatives","volume":"99","author":"DeVaries E","year":"1989","journal-title":"Laryngoscope"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348948709600602"},{"key":"e_1_2_1_16_2","unstructured":"OlofssonJ van NostrandAWP.Growth and spread of laryngeal and hypopharyngeal carcinoma with reflections on the effect of preoperative irradiation: 139 cases studied by whol organ serial scanning.Acta Otolaryngol1973;(Suppl 308):1\u201384."},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348947508400611"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-195510000-00001"},{"key":"e_1_2_1_19_2","first-page":"593","volume-title":"Head and neck imaging","author":"Curtin","year":"1991"},{"key":"e_1_2_1_20_2","doi-asserted-by":"crossref","unstructured":"OgawaY MaedaT SeguchiH et al.Application of the immunohistochemical method as a predictive assay in radiotherapy of squamous cell carcinoma of oropharynx and hypopharynx[Abstract].1990.","DOI":"10.1159\/000226809"},{"key":"e_1_2_1_21_2","unstructured":"MurakamiY YanudaN MurakamiM et al.Correlation of proliferation index with submucosal invasion of hypopharyngeal[Abstract].1990."},{"key":"e_1_2_1_22_2","volume-title":"Laryngeal cancer","author":"Lam KH","year":"1991"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199109000-00003"}],"container-title":["Head &amp; Neck"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fhed.2880150110","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/hed.2880150110","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,26]],"date-time":"2023-10-26T06:13:43Z","timestamp":1698300823000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/hed.2880150110"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,1]]},"references-count":22,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1993,1]]}},"alternative-id":["10.1002\/hed.2880150110"],"URL":"https:\/\/doi.org\/10.1002\/hed.2880150110","archive":["Portico"],"relation":{},"ISSN":["1043-3074","1097-0347"],"issn-type":[{"value":"1043-3074","type":"print"},{"value":"1097-0347","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,1]]}}}
