Although the harvesting technique and reconstructive surface have been reported, the arterial supply to the LNW flap and its clinical implications is not well defined. This study presents anatomical dissections to clarify the vascular supply to this flap, and the associated clinical outcomes from this reconstructive technique.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The course and branching pattern of the sphenopalatine artery (SPA) to the LNW were studied in 6 vascular latex\u2010injected heads (11 LNW flaps total). Patients undergoing an LNW flap since 2008 were identified and the underlying pathology, indication, flap viability, and clinical outcomes were retrospectively analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The inferior turbinate artery arises from the LNW artery and divides into 2 branches at the most posterior aspect of the inferior turbinate bone. A smaller\u2010caliber superficial branch travels anteriorly and branches to the LNW. A larger dominant branch travels into the inferior meatus and tangentially supplies the nasal floor. Twenty\u2010four patients with sellar or posterior cranial fossa (PCF) defects were reconstructed with an LNW flap. Postoperative contrast enhancement of the LWN flap was identified in 95.5% of cases. Postoperative cerebrospinal fluid (CSF) leaks were identified in 6 cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Blood supply to the nasal floor by the dominant inferior meatus branch is more robust than the supply to the anterior LNW by the superficial arterial branch. The LNW flap is the preferred vascularized reconstructive option to the PCF and sella in the absence of a nasoseptal flap (NSF).<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.22534","type":"journal-article","created":{"date-parts":[[2020,2,27]],"date-time":"2020-02-27T11:22:39Z","timestamp":1582802559000},"page":"673-678","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Lateral nasal wall flap for endoscopic reconstruction of the skull base: anatomical study and clinical series"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4539-0490","authenticated-orcid":false,"given":"Philippe","family":"Lavigne","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Belen","family":"Vega","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7923-930X","authenticated-orcid":false,"given":"Omar H.","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Gardner","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl H.","family":"Snyderman","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1180-5854","authenticated-orcid":false,"given":"Eric W.","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of Pittsburgh Medical Center  Pittsburgh PA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,2,27]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.22475"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.24319"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/mlg.0b013e318062111f"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2011.25.3693"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2009.23.3354"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200210000-00020"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.4193\/Rhin14.042"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-015-1516-6"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0033-1358791"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/ons\/opy308"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/hed.23775"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2011.06.016"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.3171\/2014.7.FOCUS14350"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.21162"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/ons\/opy002"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000365620.59677.FF"}],"container-title":["International Forum of Allergy &amp;
