The maximum advantage is offered by bilateral lateralization of the middle turbinates (102.7% increase in exposure), whereas a moderate increase is observed with each following step. Surgical freedom mainly increased during the first part of the approach, that is, with a monolateral right middle turbinectomy (17.9% raise of maneuverability), whereas additional steps did not increase surgical freedom enough to justify an aggressive nasal disruption.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Monolateral turbinectomy on the side of endoscope docking represents the best solution, optimizing working area and surgical freedom (offering increases of 116.9% and 17.9%, respectively). Bilateral turbinectomy, together with a monolateral anterior and posterior ethmoidectomy, can be reserved for selected cases (increases of 148.5% and 24.7%, respectively). Bilateral ethmoidectomy does not significantly improve surgical freedom (0.81%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>N\/A. <jats:italic>Laryngoscope<\/jats:italic> 124:2231\u20132237, 2014<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.24693","type":"journal-article","created":{"date-parts":[[2014,3,26]],"date-time":"2014-03-26T10:06:37Z","timestamp":1395828397000},"page":"2231-2237","source":"Crossref","is-referenced-by-count":19,"title":["Quantitative analysis of progressive removal of nasal structures during endoscopic suprasellar approach"],"prefix":"10.1002","volume":"124","author":[{"given":"Matteo","family":"de Notaris","sequence":"first","affiliation":[{"name":"Department of Neurosurgery Hospital Clinic, Faculty of Medicine, Universitat de Barcelona Barcelona Spain"},{"name":"Department of Human Anatomy and Embryology Faculty of Medicine, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Prats\u2010Galino","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy and Embryology Faculty of Medicine, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquim","family":"Ense\u00f1at","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Hospital Clinic, Faculty of Medicine, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Topczewski","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Hospital Clinic, Faculty of Medicine, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrique","family":"Ferrer","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Hospital Clinic, Faculty of Medicine, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi Maria","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery Department of Neurosciences Reproductive and Odontostomatological Sciences Universit\u00e0 degli Studi di Napoli Federico II Naples Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Cappabianca","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery Department of Neurosciences Reproductive and Odontostomatological Sciences Universit\u00e0 degli Studi di Napoli Federico II Naples Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico","family":"Solari","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery Department of Neurosciences Reproductive and Odontostomatological Sciences Universit\u00e0 degli Studi di Napoli Federico II Naples Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,6,3]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11102-008-0087-5"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000119325.14116.9C"},{"key":"e_1_2_6_4_1","first-page":"48","article-title":"Endoscopic cranial base surgery: ready for prime time?","volume":"54","author":"Prevedello DM","year":"2007","journal-title":"Clin Neurosurg"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.3171\/JNS-07\/07\/0206"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199905000-00020"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-211-72283-1_4"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-7091-6084-8_11"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.neu.0000289708.49684.47"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000249211.89096.25"},{"key":"e_1_2_6_11_1","first-page":"E3:1","article-title":"Expanded endonasal approach: the rostrocaudal axis.
