ROLE OF HRCT IN EVALUATION OF PATHOLOGIES OF TEMPORAL BONE AND ITS SURGICAL INTERVENTION

Background:Advanced medical imaging techniques like CT and HRCT help diagnose pathologies in the temporal bone, providing detailed visualization and insights into pathological conditions, particularly soft tissue density eg. cholesteatoma, which is difficult to diagnose through clinical examination alone. Aims and Objectives: The study aims to identify temporal bone changes in chronic suppurative otitis media patients using HRCT, correlate surgical intervention with HRCT findings, and confirm diagnosis through intraoperative findings. Methods: Total 100 patients with temporal bone pathologies. The patients were aged 10-60 years and provided clinical data. They underwent a Siemens Somatom AS 128 Slice multislice CT scan, revealing ear ossicle erosion, dural plate erosion, mastoid sclerosis, and scutum erosion. Surgical procedures were scheduled based on HRCT findings. The study compared HRCT and intraoperative findings to determine their correlation, using IBM SPSS 23rd version software and Chi-square test. Results: The study analyzed 100 patients with ossicular abnormalities, with incus erosion being the most common. Other common conditions included scutum, malleus, and stapes erosion. Sinus plate erosion was rare, while mastoid sclerosis was common but not as prevalent. Soft tissue/fluid attenuation was prevalent during intraoperative procedures, with the epitympanum having the highest prevalence at 98%, indicating density-related abnormalities. Conclusions: The data offers crucial insights into ossicular and mastoid health conditions, aiding clinicians in comprehensive assessments, accurate diagnoses, and effective treatment strategies, ultimately improving patient care and outcomes in otolaryngology.
