Perbedaan Rerata Besar Sudut Tuba Eustachius pada Pasien Otitis Media Supuratif Kronik dengan dan tanpa Kolesteatoma Berdasarkan CT-Scan Temporal di RSUP H. Adam Malik Medan

Abstract

Backgroud: Chronic Suppurative Otitis Media (CSOM) is one of the major health problems found in many population in the world and causes of high morbidity and mortality. One of the factors that predisposes to CSOM is disfunction of Eustachian tube. The more horizontal of the Eustachian tube angle causes Eustachian tube dysfunction and clearance disorders of the middie ear. Objectives: To evaluate the mean of Eustachian tube angle and to examine diffrentiation the angle of Eustachian tube in CSOM with and without cholesteato;na. 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 angle of Eustachian tube using Multiplanar Reconstruction technique on osirix program. Results: The mean of Eustachian tube angle in CSOM patients with cholesteatoma is 28,32° and CSOM without cholesteatoma is 33,03°. The mean of the Eustachian tube angle in CSOM with cholesteatoma in female patients was 28, 79° and male 27, BB° whereas in the CSOM group without cholesteatoma in female patients was 34,65° and men 31,91°· In independent T test, the result showed significant diffrentiation (p<0, 05) between mean 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 holizontal than women. There is diffrentiation the angle of the Eustachian tube in patients CSOM with and without cholesteatoma.
