Assessment of variations of anterior ethmoidal artery evaluated by computed tomography of paranasal sinuses
Journal Title: International Journal of Medical and Health Research - Year 2019, Vol 5, Issue 3
Abstract
Computed tomography (CT) has helped not only to evaluate nasosinusal disease, but also to characterize the anatomy of the paranasal sinuses. The coronal plane, in particular, is considered as a map for assessing the anatomy that varies significantly even between both sides in the same individual; this may alert about areas of potential complication risk in nasal endoscopic surgery. The present study was planned in the Department of Otorhinolaryngology (ENT), Nalanda Medical College & Hospital. Total 100 patients referred to the ENT department from January 2016 to July 2017 for computed tomography of the paranasal sinuses were enrolled in the present study. The medial notch of the orbit (anterior ethmoidal foramen) and the anterior ethmoidal sulcus on the lateral wall of the olfactory fossae were reliable parameters for identifying the course of the anterior ethmoidal artery. AEA in long mesentery with absent bony canal can be assessed preoperatively on CT PNS. In this scenario there is more chances of injury to vessel during surgery, hence care must be taken to prevent complications like orbital haematoma and haemorrhage.
