Is Computed Tomographic Scanning Alters the Management of Patients with Suspected Cholesteatoma?

Computed Tomographic Scanning in Management of Patients with Suspected Cholesteatoma

Abstract

Background: Cholesteatoma is an abnormal skin growth that can develop in middle section of your ear behind the eardrum; a cholesteatoma may also be caused by a poorly functioning eustachian tube, which is the tube that leads from the back of the nose to the middle of the ear. It causes mainly chorionic ear infection, sinus infection, cold and allergies. This may cause a section of eardrum to be pulled into middle ear, creating a cyst than can turn into cholesteatoma. Subjects and Methods: A prospective, analytical study was conducted among 90 patients with complaint of unsafe chronic suppurative otitis media which were randomly selected from outpatient Department of ENT at Shridev Suman Subharti Medical College, Dehradun, Uttarakhand. The patients comprised of both males as well as females and also of different age groups. Results: Out of 90 patients, 61(67.22%) were males followed by 29 (32.22%) females. The minimum age of patient in the study was of 8years and the maximum age of patient in study of 50 years. Maximum number of patients belonged to the age group of 11-20 (50%). The mean age in this study was 23 years. Among study subjects, 32 (35.55%) cases had conductive hearing loss, 11(12.22%) cases had sensorineural type, 40(44.44%) had mixed type and 7(7.77%) had no response. Out of 90 study subjects, 46 (51.11%) had cholesteatoma. Conclusion: The clinical and radiological findings showed a high level sensitivity with intra operative findings as regards to the presence of cholesteatoma, changes of the ossicular chain and erosion of the lateral semicircular canal. HRCT findings, in the treatment of any congenital abnormality of the ear were a good guide to the surgeon for planning and management.
