title: Simultaneous histological, audiological and radiological findings in congenital anomalies of the inner ear.
abstract: Twenty-eight cases of children with deafness or severe perceptive impairment of hearing are discussed. They are selected into two groups for the symmetrical longitudinal planigraphy of the ear, the findings of which enable us to prove a labyrinthine aplasia and to compare them with audiometric findings. Accordingly we are able to draw a definite conclusion in small children. Histological findings about congenital anomalies of the inner ear with changes in the cochlea may also be divided into two groups: 1. Complete absence of development of inner ear with labyrinth aplasia. 2. Greater or lesser aplasia in the bony part of the cochlea Subgroups: (a) classic type after Mondini; (b) partial type after Mondini.
