Abstract :

INTRODUCTION– Middle ear cholesteatoma is a relatively common disease that can lead to serious complications. High resolution computed tomography (HRCT) of temporal bone plays crucial role in diagnosis of cholesteatoma, assessing the disease extent and its various complications.

AIMS AND OBJECTIVES– To study the radiological findings and major complications of cholesteatoma diagnosed on computed tomography (CT) which requires early surgical management.

MATERIALS AND METHODS– This was a prospective study carried out on 30 patients who presented with ear discharge and conductive ear loss to the department of ENT, Mullana ,Ambala. HRCT was done in all the patients suspected of cholesteatoma with 128 slice MDCT, INGENUITY (Philips Medical SystemsUSA) in the Department of Radiodiagnosis and imaging.

RESULTS– Out of 30 patients 16 were male patients and 14 were female patients. The most frequently encountered symptoms were discharging ear, impaired heå and headache. The most common space to be involved by cholesteatoma was epitympanum with mastoid cells opacification. Maximum erosion of the incus was seen. Tegmen tympani erosion was the most encountered complication.

CONCLUSION– HRCT by using its multiplanar qualities is highly accurate and specific in detecting cholesteatoma and its various complications.
