[Value of visually evoked potentials in lesions of the optic nerve caused by a mucocele].
Mucoceles originating in accessory paranasal sinuses with orbit involvement are quite rare. The authors describe two cases of mucoceles, revealed by CT-Scan, the first in the ethmoid-sphenoidal-maxillary sinuses and the other in the ethmoid-frontal sinuses respectively. In both cases Visual Evoked Potentials were most important for assessing optic nerve involvement. They were also useful to check post surgical recovery. These case reports emphasize that early diagnosis of mucoceles involving the optic nerve is very important because prompt surgical treatment may lead to recovery of visual disturbances.
