Comparison of Preoperative High Resolution Computed Tomography Findings and Intraoperative Findings in Patients with Chronic Suppurative Otitis Media
Abstract: Chronic suppurative otitis media (CSOM) remains a significant cause of hearing impairment globally, particularly in developing nations. The disease is classified into "safe" tubotympanic and "unsafe" atticoantral types, the latter often involving aggressive pathologies like cholesteatoma. This prospective study aims to evaluate the diagnostic efficacy of High-Resolution Computed Tomography (HRCT) of the temporal bone by comparing preoperative imaging with intraoperative findings in 60 patients. The research was conducted at Government Medical College, Amritsar, using a 64-slice multidetector CT scanner with 1.25 mm slice thickness. Following imaging, all patients underwent surgical exploration. Results indicated a female predominance (55%) and a peak incidence in the 10?20 year age group (48.3%). HRCT demonstrated exceptionally high sensitivity for detecting soft tissue in the attic (100%) and identifying sinus plate erosion (100%). The incus was the most frequently eroded ossicle, with HRCT showing 92.31% sensitivity. However, HRCT showed limited accuracy for stapes erosion (22.22% sensitivity) and identifying disease in deep recesses like the sinus tympani (66.67% sensitivity). In conclusion, HRCT is an indispensable preoperative tool that serves as a detailed roadmap for surgeons, identifying critical bony erosions and mapping disease extent. Despite its limitations in visualizing minute structures like the stapes, it significantly enhances surgical planning and safety.
