First, a frontal sinusotomy and ethmoidectomy were performed via an endoscopic endonasal approach in order to fully expose the anterior skull base. Subsequently, the lamina papyracea and the bone of the canals covering the ethmoidal neurovascular bundles were removed to identify the anterior, middle, and posterior ethmoidal arteries. Presence, laterality, and location of the middle ethmoidal artery were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 14 middle ethmoidal arteries were identified (10 right and 4 left), among 44 sides (22 specimens), accounting for an incidence of 31.8%. Bilateral middle ethmoidal arteries were found in 3 of 22 specimens (14%). Endonasal endoscopy features of the middle ethmoidal artery were noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This is the first study assessing the anatomical features of the middle ethmoidal arteries from an endonasal endoscopic perspective. The findings of this research have clinical significance in guiding surgeries that involve the medial orbital wall, intractable epistaxis, and anterior skull base pathologies, as well as endoscopic endonasal surgeries.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21255","type":"journal-article","created":{"date-parts":[[2013,12,5]],"date-time":"2013-12-05T18:36:47Z","timestamp":1386268607000},"page":"164-168","source":"Crossref","is-referenced-by-count":26,"title":["Endoscopic anatomy of the middle ethmoidal artery"],"prefix":"10.1002","volume":"4","author":[{"given":"Liang","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"},{"name":"Department of Otolaryngology\u2013Head and Neck Surgery 1st Affiliated Hospital Zhengzhou University  Zhengzhou Henan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Youseef","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdul Aziz","family":"Al Qahtani","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramazan","family":"Gun","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel M.","family":"Prevedello","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley A.","family":"Otto","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leo","family":"Ditzel","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo L.","family":"Carrau","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wexner Medical Center The Ohio State University  Columbus OH"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,12,5]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"356","article-title":"Ethmoid orifices and canals;
