Abstract

Background:Chronic otitis media remains a significant health problem in terms of prevalence,
economics, and sequelae. Chronic otitis media is chronic inflammation of middle ear and mastoid
cavity characterized by discharge from middle ear through a perforated tympanic membrane.
AIM: To study the radiological findings of the temporal bone in patients with chronic otitis media
with or without cholesteatoma and to study the correlation of High Resolution CT scan of
temporal bone with intraoperative findings.
Material & Methods: Study Design: Prospective cross-sectional study. Study area: The study
was done in the Department of and Radio diagnosis, RMC Jalaun (Orai), UP. Study Period: 1
year. Study population: patients attending/referred to the department of Radio diagnosis for High
resolution computed Tomography of temporal bone. Sample size: 40 cases have been included in
the present study. Sampling method: Simple Random sampling method. Statistical Analysis:The
data was collected, compiled and compared statistically by frequency distribution and percentage
proportion. Quantitative data variables were expressed by using Descriptive statistics (Mean ±
SD). Qualitative data variables were expressed by using frequency and Percentage (%).
Results: Out of 30 cases of atticoantral disease, HRCT showed findings of cholesteatoma in 27
cases. Surgically cholesteatoma was present in 26 cases. The findings were correlated with
surgical outcome by diagnostic statistics.
CONCLUSION:HRCT of temporal bone plays a promising role in pre-operative assessment of
cholesteatoma as it depicts the extent of the disease and integrity of most of the middle ear
structures.
