title: [Radiological evaluation of major aplasias of the ear].
abstract: Results of radiologic, radiotomographic and CT scan imaging of patients with major aplasias of ear are presented. In the absence of an indication for functional surgery these explorations allow evaluation of the risk of an epithelial inclusion within an undetected anlage of external auditory canal. When functional surgery is indicated results of these investigations allow assessment of pneumatization of petrous bone, possibility of construction of a new external auditory canal, and the internal ear. Study of middle ear is still insufficient in the region of the ossicula, particularly the fenestrae and stapes.
