Unilateral sensorineural hearing loss secondary to internal auditory canal stenosis in a 12-year old
female: A therapeutic dilemma

U
nilateral hearing loss is a significant complaint that is often encountered inotolaryngology practice and if leftuninvestigated,
it may have dire consequences. In this case, we encountered a rare condition of a 12-year old girl who initially presented
with progressive unilateral sensorineural hearing loss, with no evidence of facial palsy. Neuroimaging demonstrated stenosis of
the internal auditory canal. Isolated cases of congenital primary stenosis of the internal auditory canal (IAC) is a rare condition
although other temporal bone conditions may also accompany this condition. Even though most patients exhibit sensorineural
hearing loss, there are also cases wherein the hearing is normal in patients with stenotic canals, leading several studies to
investigate the causal link between this anatomic abnormality and deafness. Typical radiographic findings are described in this
case and the relevant embryological origins of the ear are traced in detail. The association of isolated IAC stenosis and hearing
loss in this case suggests a correlation between stenosis and deafness. Most of the literature is focused on the effect of IAC
stenosis on the outcome of cochlear implantation. There is currently no consensus regarding the therapeutic management for
these types of cases since there are only a few reports in literature.
