| description | BACKGROUND: Hearing impairment is a
major disability. The otologic assessment
together with high-resolution CT images is
an important step to obtain precise
diagnostic profile of ear malformations.
This study was conducted to obtain the
detailed anatomy and objective assessment
of the ear in patients presenting with
hearing loss in a tertiary care otologic center
using high-resolution CT scan.
METHODS: A cross-sectional study of 55
patients with hearing loss who had
undergone high-resolution CT scans at
Hospital Universiti Sains Malaysia from 1st
January 2008 until 31st May 2014. Patients
with temporal bone fractures, malignancy,
post-operative ear and cholesteatoma were
excluded.
RESULTS: Nine patients noted to have
external ear anomaly on right ear and 7
patients on left ear. Middle ear abnormality
in both ears was seen in 2 patients. Patients
noted to have cochlear anomaly on the right
ear (R) were 8 and left ear (L) were 4.
Measurements of vestibular aqueduct
diameter were 0.08 ± 0.09 cm (R) and 0.06 ±
0.04 cm (L), lateral semicircular canal
diameter 0.10 ± 0.03 cm (R) and 0.10 ± 0.02
cm (L), vestibule diameter 0.30 ± 0.06 cm
(R) and 0.31 ± 0.05 cm (L), bone width
between the lateral vestibular wall and the
inner wall of the lateral semicircular canal
diameter 0.35 ± 0.07 cm (R) and (L) and
internal acoustic meatus diameter 0.40 ±
0.08 cm (R) and 0.41 ± 0.08 cm (L). One
patient had cochlear aplasia and common
cavity deformity, 2 patients had lateral
semicircular dehiscence and internal acoustic
meatus stenosis, 4 patients had cochlear
ossification and 5 patients were noted to
have enlarged vestibular aqueduct.
CONCLUSION: High-resolution CT scan
image is a good single imaging modality to
obtain an objective measurement of the ear
as well as to detect subtle or underestimated
ear anomalies |
