The aim of this article is to describe how we can get a reliable 3D sphenoidal anatomical reconstruction for surgical planning by using a user-friendly, accurate, and free image software.<\/jats:p><jats:p>\n          Methods\u2003Free computer software (OSIRIX Medical Imaging Software) was used to create in a personal computer a three-dimensional (3D) reconstruction of the sphenoid sinus (SS) based on head computed tomography angiographies (CTAs) from a series of 67 patients who were operated for sellar tumors during a 4-year period (March 2016 to March 2020). The aim of the 3D reconstruction with OSIRIX was to reveal preoperatively the most important intrasphenoidal structures seen from the endonasal point of view.<\/jats:p><jats:p>\n          Results\u2003The intraoperative visible sphenoidal structures were previously recognized in the virtual 3D reconstructed image with 100% of specificity (SP) and positive predictive value. The OSIRIX view by using region of interest points allowed us to see preoperatively the internal carotid artery parasellar course even in those cases in which it was hidden by bone or tumor. Moreover, the 3D reconstruction was able to provide a clear differentiation between the tumor and the pituitary gland when both structures were in contact with the sellar floor.<\/jats:p><jats:p>\n          Conclusion\u2003Our experience with the OSIRIX software from CTA as preoperative planning for endonasal pituitary surgery was valuable, because it gave us access in simple way to a free and reliable 3D image of the SS.<\/jats:p>","DOI":"10.1055\/s-0041-1725169","type":"journal-article","created":{"date-parts":[[2021,3,13]],"date-time":"2021-03-13T00:01:50Z","timestamp":1615593710000},"page":"e244-e252","source":"Crossref","is-referenced-by-count":3,"special_numbering":"S","title":["Three-Dimensional Reconstruction of the Sphenoid Sinus Anatomy for Presurgical Planning with Free OSIRIX Software"],"prefix":"10.1055","volume":"83","author":[{"given":"Javier","family":"Abarca-Olivas","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Instituto de Investigaci\u00f3n Sanitaria y Biom\u00e9dica de Alicante (ISABIAL), Alicante University General Hospital, Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"B\u00e4rtschi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hospital de Jaen, Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irene","family":"Monjas-C\u00e1novas","sequence":"additional","affiliation":[{"name":"Department of ENT, Alicante University General Hospital, Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Gonz\u00e1lez-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Instituto de Investigaci\u00f3n Sanitaria y Biom\u00e9dica de Alicante (ISABIAL), Alicante University General Hospital, Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Garc\u00eda-Garrig\u00f3s","sequence":"additional","affiliation":[{"name":"Department of Radiology, General University Hospital Alicante, Isabial, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose","family":"S\u00e1nchez-Pay\u00e1","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, General University Hospital Alicante, Isabial, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Moreno-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Instituto de Investigaci\u00f3n Sanitaria y Biom\u00e9dica de Alicante (ISABIAL), Alicante University General Hospital, Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,3,12]]},"reference":[{"issue":"06","key":"ref1","doi-asserted-by":"crossref","first-page":"E10","DOI":"10.3171\/FOC.2008.25.12.E10","article-title":"Comparison of endoscopic and microscopic removal of pituitary adenomas: single-surgeon experience and the learning curve","volume":"25","author":"B W O'Malley Jr","year":"2008","journal-title":"Neurosurg Focus"},{"issue":"03","key":"ref2","first-page":"343","article-title":"The role of endoscopic endonasal approach to pituitary tumours: HUKM experience","volume":"61","author":"B S Gendeh","year":"2006","journal-title":"Med J Malaysia"},{"issue":"02","key":"ref3","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1097\/00006123-199702000-00001","article-title":"Complications of transsphenoidal surgery: results of a national survey, review of the literature, and personal experience","volume":"40","author":"I Ciric","year":"1997","journal-title":"Neurosurgery"},{"issue":"12","key":"ref4","doi-asserted-by":"crossref","first-page":"1416","DOI":"10.1007\/BF01411120","article-title":"Endoscopy assisted transsphenoidal surgery for pituitary adenoma.
