[ENT and neurosurgical team approach to malignant ethnoido-frontal tumors].

: The authors describe a surgical technique of total ethmoidectomy by mixed frontal and paralateronasal duct for excision of the ethmoidal bloc tumors. This technique requires a surgical team aware of neurosurgical and ORL problems. The authors report their experience on a series of six patients, surgically managed from 1983 to 1990.
