[Echographic diagnosis of the ethmoid sinus. II: Clinical findings].

We report on our first clinical results of the echographical examination in ethmoidal diseases using the transocular sound beam direction, and present the A- and B-scan findings in ethmoidal inflammation, mucoceles and tumours. If bony defects in the medical orbital wall and orbital involvement are present, standardized A-scan sonography enables us not only to detect, localise and measure, but also to differentiate various ethmoidal tumours.
