Abstract
The
duplicated narrow Internal Auditory Canal (IAC) is a congenital anomaly of the
ear that leads to unilateral sensorineural hearing
loss. We present a rare case
of an IAC with duplication in an 11-year-old
boy. High-resolution Computed Tomography (CT) and Magnetic Resonance Imaging
(MRI) were used to visualize the bone
structure and evaluate neural components, respectively. CT scan revealed
the narrowing of the IAC diameter. MRI showed
the significant thinning of the right cochlear nerve and inferior vestibular
nerve. This is a unique case as it is the first case reported in the literature
of unilateral internal auditory canal duplication with severe sensorineural
hearing loss where an air-conduction hearing aid was helpful. Diagnosis of
unilateral sensorineural hearing loss in adolescents should encompass a
physical examination, audiometric tests and imaging modalities such as HRCT and
MRI.
