Dysplasias of the external auditory canal can be evaluated with high resolution CT using proper technique. Images are studied to determine the type of atresia (membranous or bony) nnd the thickness of the associated atretic plate (if present). Other findings sought include the degree of pneumatization, the status of the fenestrae, the size of the tympanic cavity, and the location of both the mandibular condyle and the facial nerve canal.
