Background: Chronic Suppurative Otitis Media (CSOM) is a significant cause of preventable hearing loss. Global emergence of resistant strains is of great concern. The aim of the present study was to assess the accuracy and predictive value of computed tomography in diagnosis of unsafe chronic suppurative otitis media. Methods: Aprospective, analytical study was conducted among 90 patients with complaint of unsafe chronic suppurative otitis media which were randomly selected from outpatient Department of Otorhinolaryngology at 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. In this study, sensitivity, specificity, positive predictive value, negative predictive value was calculated of computed tomography findings as compared to preoperative findings. The sensitivity of HRCT for mastoid was 100%, visualization malleus was 94.11%, incus was also 62.31%, stapes was 47.22% and facial N dehiscent and intact was 44.82%. Similarly, the specificity of CT scan for mastoid was 83.33%, malleus was 92.85%, incus was 61.90%, stapes erosion was 37.03% and facial N dehiscent was 96.72%. Conclusion: The present study was concluded that computed tomography can accurately image the findings in unsafe chronic suppurative otitis media and represents a major advance in the diagnostic imaging of this disease.

Background: Chronic Suppurative Otitis Media (CSOM) is one of the most common causes of preventable hearing loss especially in developing countries. It is described as a condition of the middle ear that is characterized by persistent or recurrent discharge for three months or more through a perforation of the tympanic membrane. The aim and objective of the study is to correlate and compare preoperated computed tomography with preoperative surgical findings with unsafe chronic suppurative otitis media. 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: Among 90 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. On comparing the per operative findings with those of computed tomography, soft tissue mass in middle ear and mastoid was seen in 87 cases (96.66%) per operatively whereas on computed tomography, it was observed in 80 cases (88.88%). Mastoid air cells were found sclerosed in 72 cases (80%) both per operatively and on computed tomography. Conclusion: In conclusion, the present study pointed that high resolution computed tomography scanning is a modality which can accurately image the pathological anatomy in unsafe chronic suppurative otitis media and represents a major advance in the diagnostic imaging of this disease.

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.
