Abstract

Background: Chronic Suppurative Otitis Media (CSOM) is one of the major health problems found in many populations in the world and a cause of high morbidity and high mortality. However, there is no single theory that explains how and why chronic otitis media occurs. There are many studies on the function of Eustachian tube. However, the role of the Eustachian tube angle and the relationship with the occurrence of CSOM has not been widely studied. This study aimed to evaluate the mean of Eustachian tube angle and to examine the diffrentiation between angle of Eustachian tube in Chronic Suppurative Otitis Media (CSOM) patient with and without cholesteatoma.

Subjects and Methods: This research is a case-control study. Study group consist of 27 patients of CSOM with cholesteatoma and 27 patients of CSOM without cholesteatoma included as controlling. All patients are examined by using CT temporal and measured the angle of Eustachian tube using Multiplanar Reconstruction (MPR) technique on osirix program. The data was analyzed using independent T test

Results: The mean of the Eustachian tube angle in CSOM with cholesteatoma in female patients was 28.690 and male 27.780 whereas in the CSOM group without cholesteatoma in female patients was 33.810 and men 31.870. The mean of Eustachian tube angle in CSOM patients with cholesteatoma is 28.220 and CSOM without cholesteatoma is 33.000. In independent T test, the result showed significant differentiation (p= 0.001) between the angle of Eustachian tube in patients CSOM with and without cholesteatoma.

Conclusion: The advance of technology makes easier to measure of Eustachian tube angle. In men found that the Eustachian tube angle is more horizontal than women. There is diffrence between the angle of the Eustachian tube with the occurrence of cholesteatoma in CSOM.

Keywords: angle of Eustachian tube, CSOM
