ABSTRACT

For the ethmoidal nerve block, local anesthetics can be injected by passing the supraorbital notch to the anterior and posterior ethmoidal foramina. We measured the distances from supraorbital notch to anterior and posterior ethmoidal foramina, optic foramen and the angles formed by the selected points in the orbit to use this anatomical values in performing ethmoidal nerve block. The measured mean distances from supraorbital notch to the anterior and posterior ethmoidal foramina were 22.9 and 34.1mm respectively. Direction of injection was medial, inferior and posterior from the medial of supraorbital notch.
