Neuroradiological intervention in the region of the paranasal sinuses is basically similar to intervention in other areas of the head and neck. The vessels involved are the external and internal carotid arteries. Great strides forward have been made in the past few years due to the development of new embolic materials and new catheter systems, with new microcatheters as fine as 1F in diameter and combined with detachable balloons (Debrun 1983). The super-selective catheterization enables the operator to place the catheter tip very near the pathological lesion and to deliver the emboli accurately without compromising adjacent healthy tissues. The indications for intervention have thus been widened and the complication rate reduced.
