Abstract:
This study was aimed to study the temporal bone diseases using HRCT.
Data was obtained retrospectively from 52 patients of different ages and gender
who are selected from ENT hospital and clinically suspected of having
symptoms related to the temporal bone such as ear discharge, conductive hearing
loss, vertigo and facial palsy. traumatic patients wereexcluded.
The study was done at Alzaytouna specialist hospital& Antalya medical
center during 2016 year. HRCT images were obtained by taking 2mm sections
using ultra high algorithm in both coronal and axial planes. contrast media was
used as and when required. The results were then analyzedstatistically.
In this study temporal bone diseases were more common in female 60% than
male population 40%. Majority of patient are in the age group of 21-40 years .
Infection was the most common pathology 82 %, followed by neoplasm (benign
and malignant) 10 %, congenital malformation 2% and other pathological lesions
6%.The incidence of unilateral involvement 66% ismore than bilateral
involvement 34%.
HRCT has major role in the demonstration of detailed anatomy and
identifying various findings related to the location ,extent and complication of
thedisease.
HRCT can able to evaluate air space and bony structure and it can detect the
presence of opacification and soft tissue density but cannot able to distinguish
the type of tissues , the clinical correlation and biopsy was advised in thiscases.
HRCT has a great importance in guiding the surgical approach that can
prevent further serious complications.
