“The Accessory Ethmoidal Canal Does Not Necessarily Contain an Arterial Structure”

Abstract: Introduction: The aim of our study is to describe the prevalence of the accessory ethmoidal artery in endonasal endoscopic cadaver dissections and to identify its intraorbital origin. Material and Methods: From 2018 to 2020, thirty-four nasal dissections were performed in seventeen adult cadaveric heads. We performed a complete ethmoidectomy to identify the ethmoidal canals. Then, we removed the bony canal and the lamina papiracea to verify the injected vessel and to confirm the vascular structure inside the c… Show more

“…5 Os achados desta pesquisa têm significado clinicamente relevante durante as cirurgias da parede medial da órbita, para epistaxes intratáveis e tumores da base anterior do crânio, bem como nas cirurgias endoscópicas tradicionais 5 . Logo, demonstra-se ser fundamental para intervenção da epistaxe a compreensão anatômica da artéria etmoidal acessória ou média, para procedimentos cirúrgicos endoscópicos endonasais da base anterior do crânio e cirurgias orbitárias endonasais 46 .…”

“…Conforme os resultados, sugestionou-se que a existência do canal não implica a existência do vaso arterial, e que a existência da artéria etmoidal acessória ou média mantém-se relacionada à inexistência da artéria etmoidal posterior 46 . No entanto, a supressão da vascularização da artéria etmoidal posterior pode ser retribuída pela artéria etmoidal acessória ou artéria etmoidal média 46 .…”
