Morphological alterations of the cranio-cervical junction as a basilar impression, a ponticulus posterior, an atlas assimilation, an intervertebral narrowing, and spondylosis deformans were found radiologically. There was no difference to a healthy population. ⋯ Especially very high standard deviations in the atlanto-occipital and the atlanto-dental joint are interpreted as hypermobile as well hypomobile atlas joints. These results indicate a correlation between sudden deafness and functional pathology of the craniocervical junction.
