Anatomical references are essential to safely perform these surgeries.<\/jats:p><jats:p>\n          Objective\u2003To measure and compare the distance from the posterior wall of the maxillary sinus to the anterior skull base in cadavers and on computed tomography (CT) scans to determine a measurement as an anatomical reference in imaging exams for sinus and anterior skull base surgery.<\/jats:p><jats:p>\n          Methods In dissections and CT scans, we took measurements from the most upper and medial point of the posterior wall of the maxillary sinus (point A) to the point where the skull base deflects and the anterior sphenoid wall is formed (\u0394 90\u00b0; point B), in the right and left nasal cavities. We used 51 cadavers aged \u2265 18 years in the present research.<\/jats:p><jats:p>\n          Results\u2003The measurements obtained from CT scans and dissections were greater than 1.5\u2009cm in all cadavers, and they were positively correlated. The 1-cm increase in the AB-tomography measurement corresponded to the 1.08-cm increase to the right and 1.07-cm to the left in the AB-dissection measurement.<\/jats:p><jats:p>\n          Conclusion\u2003The CT measurements may be considered a reliable tool to promote safe and effective access to the paranasal sinuses, matching the distance that should be dissected until the anterior base of the skull.<\/jats:p>","DOI":"10.1055\/s-0043-1777447","type":"journal-article","created":{"date-parts":[[2024,7,5]],"date-time":"2024-07-05T23:31:13Z","timestamp":1720222273000},"page":"e424-e431","source":"Crossref","is-referenced-by-count":2,"title":["Anatomical Measurement as a Reference for Functional Endoscopic Sinus Surgery Based on CT Scans and Dissections"],"prefix":"10.1055","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5760-1307","authenticated-orcid":false,"given":"Andressa Vinha","family":"Zanuncio","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universidade Federal de S\u00e3o Jo\u00e3o del-Rei, Campus Centro Oeste, Divin\u00f3polis, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fl\u00e1via Gontijo","family":"Amaral","sequence":"additional","affiliation":[{"name":"Department of Radiology, Universidade Federal de S\u00e3o Jo\u00e3o del-Rei, Divin\u00f3polis, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcell de Barros Duarte","family":"Pereira","sequence":"additional","affiliation":[{"name":"Department of Radiology, Universidade Federal de S\u00e3o Jo\u00e3o del-Rei, Divin\u00f3polis, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fl\u00e1vio Barbosa","family":"Nunes","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto Eust\u00e1quio Santos","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,7,5]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"publisher","first-page":"217","DOI":"10.1385\/CRIAI:30:3:217","article-title":"Sinus surgery: indications and techniques","volume":"30","author":"A Luong","year":"2006","journal-title":"Clin Rev Allergy Immunol"},{"issue":"03","key":"ref2","doi-asserted-by":"publisher","first-page":"453","DOI":"10.1016\/j.otc.2004.10.024","article-title":"Accuracy and cost analysis of image-guided sinus surgery","volume":"38","author":"S A Hemmerdinger","year":"2005","journal-title":"Otolaryngol Clin North Am"},{"issue":"03","key":"ref3","doi-asserted-by":"publisher","first-page":"299","DOI":"10.1590\/s0034-7299200 2000300002","article-title":"Opera\u00e7\u00e3o micro-endosc\u00f3pica dos seios paranasais: conceitos b\u00e1sicos","volume":"68","author":"A Stamm","year":"2002","journal-title":"Rev Bras Otorrinolaringol"},{"issue":"04","key":"ref4","doi-asserted-by":"publisher","first-page":"256","DOI":"10.1590\/s0100-398420 11000400012","article-title":"Varia\u00e7\u00f5es anat\u00f4micas das cavidades paranasais \u00e0 tomografia computadorizada multislice: o que procurar?","volume":"44","author":"C MNR de Miranda","year":"2011","journal-title":"Radiol Bras"},{"issue":"03","key":"ref5","doi-asserted-by":"publisher","first-page":"296","DOI":"10.1016\/j.ejrad.2003.08.012","article-title":"Remarkable anatomic variations in paranasal sinus region and their clinical importance","volume":"50","author":"M Kantarci","year":"2004","journal-title":"Eur J Radiol"},{"issue":"306","key":"ref6","doi-asserted-by":"publisher","first-page":"51","DOI":"10.1016\/ j.morpho.2010.03.003","article-title":"Neighbouring relations of the posterior ethmoid studied by axial computed tomography","volume":"94","author":"M D Scutariu","year":"2010","journal-title":"Morphologie"},{"issue":"07","key":"ref7","doi-asserted-by":"publisher","first-page":"745","DOI":"10.1002\/ca.20507","article-title":"Sphenoid sinus: an anatomic and endoscopic study in Asian cadavers","volume":"20","author":"H KK Tan","year":"2007","journal-title":"Clin Anat"},{"issue":"03","key":"ref8","doi-asserted-by":"publisher","first-page":"349","DOI":"10.1016\/j.bjorl.2016.04.020","article-title":"Postoperative otorhinolaryngologic complications in transnasal endoscopic surgery to access the skull base","volume":"83","author":"R LL Dolci","year":"2017","journal-title":"Rev Bras Otorrinolaringol (Engl Ed)"},{"issue":"02","key":"ref9","doi-asserted-by":"publisher","first-page":"146","DOI":"10.5935\/1808-8694.20140030","article-title":"Endoscopic endonasal transphenoidal resection of pituitary adenomas: Preliminary evaluation of consecutive cases TT -
