Frontal sinusotomy, with an osteoplastic technique, call for osteotomies, guided by a template obtained from a Caldwell radiographic view taken at a distance of 6\u00a0feet. The reliability of the template depends on the position of the patient, distance at which the radiograph is taken, penetration of the x\u2010rays, and other technical aspects. Therefore the template is a potential source of error. We present the use of a computer\u2010assisted frontal sinusotomy as a method to corroborate the shape and margins of the frontal sinus in six patients undergoing obilterative frontal sinus surgery. In our hands, this technique has proved more reliable than the radiographic template to corroborate the positioning of the osteotomies.<\/jats:p>","DOI":"10.1177\/019459989411100605","type":"journal-article","created":{"date-parts":[[2017,7,11]],"date-time":"2017-07-11T18:21:15Z","timestamp":1499797275000},"page":"727-732","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Computer\u2010Assisted Frontal Sinusotomy"],"prefix":"10.1002","volume":"111","author":[{"given":"Ricardo L.","family":"Carrau","sequence":"first","affiliation":[{"name":"Department of Otolaryngology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carl H.","family":"Snyderman","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh B.","family":"Curtin","sequence":"additional","affiliation":[{"name":"Department of Radiology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane L.","family":"Weissman","sequence":"additional","affiliation":[{"name":"Department of Radiology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,5,18]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"2115","volume-title":"Otolaryngology","author":"Montgomery WW","year":"1980"},{"key":"e_1_2_1_3_1","first-page":"523","article-title":"Osteoplastic frontal sinusotomy: An analysis of 250 operations","volume":"85","author":"Hardy JM","year":"1976","journal-title":"Ann Otol"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/019459989210600408"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199108000-00018"}],"container-title":["Otolaryngology\u2013Head and Neck Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/019459989411100605","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/019459989411100605","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T10:26:46Z","timestamp":1760956006000},"score":1,"resource":{"primary":{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/10.1177\/019459989411100605"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1994,12]]},"references-count":4,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1994,12]]}},"alternative-id":["10.1177\/019459989411100605"],"URL":"https:\/\/doi.org\/10.1177\/019459989411100605","archive":["Portico"],"relation":{},"ISSN":["0194-5998","1097-6817"],"issn-type":[{"type":"print","value":"0194-5998"},{"type":"electronic","value":"1097-6817"}],"subject":[],"published":{"date-parts":[[1994,12]]},"assertion":[{"value":"1994-05-06","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2016-05-18","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
