Findings of Hrct Temporal Bone Vs Intraoperative Findings in Cholesteatoma - a Correlative Study

Year: 2025
Type: article
Study design: Observational Study
Abstract: Background: Chronic suppurative otitis media with Cholesteatoma evaluated with HRCT Temporal bones is widely used for anatomical and pathological diagnosis. The Radiological findings are to be correlated with the intraoperative findings to confirm the radiological diagnosis which would help the surgeons in planning the surgeries. Aim of the Study: ToassesstheusefulnessofapreoperativeHRCTtemporalboneandestablishHRCT as an efficacious tool for diagnosis of the extent and involvement of adjacent structures by Cholesteatoma. Materials:50 patients diagnosed clinically as chronic suppurative otitis media with acquired cholesteatoma were studied with the help of HRCT temporal bones and intraoperative finding for correlation. Standard operative procedures were applied in undertaking HRCT and Surgical treatment of the Choesteatoma after thorough clinical evaluation and laboratory diagnosis. Results: Among the 50 patients included majority were 15/50 (30%) in the age group of 31-40 years followed by 12/50 (24%) who were in the age group of 21-30 years. Only few were in the extremes of age groups. Disease observed in patients aged more than 60 patients could be due to slow progression. The mean age distribution of the patients is 33.14 ± 13.70 years. The most common ossicle involved was Incus (longprocess)in22/50patients (44%) on HRCT and intraoperatively in 26/50 (52%) with a Sensitivity of 84.6 and specificity 100% (p-value= <0.001). Conclusions: The results of this study suggest that preoperative HRCT imaging in cases of cholesteatoma, ossicular chain erosion has good correlation with intraoperative findings. However, HRCT is not able to distinguish between cholesteatoma and mucosal disease, Facial canal dehiscence, Incus and Malleuserosions in the early stages.
