Abstract/OtherAbstract:
INTRODUCTION AND OBJECTIVES: Our aim was to study the radiological anatomy of the ethmoidal arteries. METHODS: A descriptive study was performed including CT images of 20 cadaver heads. The specimens were perfused with a radiopaque material and various anatomical parameters were analysed. RESULTS: The anterior ethmoidal artery was found in 95% (38/40) of cases. It originated from the ophthalmic artery in 87.5% (34/40) of nasal cavities. In six cases, normal variants were found. The mean length of the anterior ethmoidal canal was 8.43±0.74mm. The angle performed into the skull base was 37.3±5.48°. In 90% of cases (36/40), it was located between the second and third lamella. The posterior ethmoidal artery was localised only in 14/40 cases, with 28.5% (4/14) of them showing normal variants. The mean length of the posterior ethmoidal canal was 7.1±1.02mm. The angle performed into the skull base was 7.11±4.07°. The distance from sill to the anterior ethmoid artery was 55.51±5.52mm. The angle between the nasal spine and the anterior ethmoidal canal was 57.67±1.68°. The distance between the nasion and the anterior ethmoidal canal was 29.31±2.53mm, the distance was 11.24±2.14mm from the anterior ethmoid artery to the posterior ethmoid artery and from the posterior ethmoid artery to the optic nerve, 7.26±1.33mm. Supraorbital cells were observed in 15% (6/40) of the cases. CONCLUSIONS: A complete vascular study of the ethmoidal arteries was possible by using this technique.
