ABSTRACT
Severe to profound sensoryneural hearing loss can be originated
by many factors including: congenital, infections, metabolic
disorders, traumatic, postquirurgical and unknown
etiologies.
Computed Tomography (CT) has been used in the evaluation
of patients with sensoryneural hearing loss who will
have undergone cochlear implants. To date, CT and MR are
very useful tools to detect normal and morphologic abnormalities
encountered in patients with deafness.
The purpose of this study is to show our experience in
patient with sensoryneural hearing loss due to labyrinthine
ossification, mainly studied by CT, and show the findings observed
in bony labyrinth.
