Abstract :

INTRODUCTION: HRCT, a modification of routine CT provides a direct visual window into the temporal bone providing hitherto unavailable minute structural details. The purpose of the study is primarily to understand the capability of HRCT in diagnosis and detection of pathologies of the temporal bone. AIMS AND OBJECTIVES: 1. To study various imaging patterns on High Resolution Computed Tomography in chronic infectious middle ear diseases and inflammations. 2. To evaluate the extent and sites of involvement of the middle ear and the mastoid air cell system in 50 patients. 3. To study the effect of infections of the tympano –mastoid compartment on the adjacent, critical and important neurovascular structures. 4. To provide a road map to the surgeon prior to patient’s management plan. PATIENTS, MATERIALS AND METHODS: The study was conducted at GOVERNMENT GENERAL HOSPITAL, GUNTUR. We included patients clinically suspected to have infectious disease of the middle ear, who were referred for HRCT of the temporal bone in our hospital during a period of 19 months from January 2017 to August 2018. Unenhanced CT of the PNS was performed for 50 patients in the axial plane, complemented by coronal and sagittal reconstructions. The investigations were performed by using a GE BRIGHTSPEED 16 slice spiral CT machine. OBSERVATIONS AND RESULTS: During the period of 19 months of the study, 50 patients who fulfilled the inclusion criteria were studied, out of which 52 percent were male and 48 percent were female. Most of the patients were in the 20–30 years age group comprising 55 percent of the study population. Patients with the clinical suspicion of middle ear infections were sent for evaluation with HRCT of the temporal bone. All 50 patients had positive findings indicating infectious disease of the middle ear.
