ABSTRACT
We studied the ethmoidal arteries using preexisting computer tomography of the paranasal sinuses (CT PNS) and statistically scrutinized data obtained between genders. A descriptive study from 77 CT PNS dated January 2016-December 2016 were collected and reviewed by two radiologists. A total of 54 (108 sides) CT PNS were studied of patients aged 18-77 years. 37 are male, 17 are female; with Bumiputera Sarawak predominance of 25 patients, 12 Malays, 16 Chinese and one Indian. Rate of identification are as follows anterior ethmoidal artery (AEA)-100%, middle ethmoidal artery (MEA)-30%, posterior ethmoidal artery (PEA)-86%. The average distance from AEA-MEA is 8.1 ± 1.52 mm, MEA-PEA is 5.5 ± 1.29 mm and AEA-PEA is 12.9 ± 1.27 mm. The mean distance from PEA-the anterior wall of sphenoid is 7.7 ± 3.96 mm, and PEA-optic canal is 8.5 ± 3.1 mm with no statistical difference when compared between gender. AEA frequently presented with a long mesentery 57.4%, while 87.1% of PEA was hidden in a bony canal. The vertical distance of the AEA-skull base ranges from 0 to 12.5 mm whilst PEA-skull base is 0-4.7 mm. There is no statistical difference in distances of AEA, MEA nor PEA to skull base when analyzed between genders; t(82) = 1.663, p > 0.05, t(32) = 0.403, p > 0.05 and t(75) = 1.333, p > 0.05 respectively. We newly discovered, that 50% of MEA is hidden in a bony canal, and its distance to skull base ranged 0-5.3 mm. MEA and PEA less commonly have a short or long mesentery. Knowledge on the ethmoidal arteries especially in our unstudied population of diverse ethnicity, gains to assist surgeons worldwide, when embarking in endoscopic transnasal surgeries.
