Correlation of Cholesteatoma Stadium with Degree of Erosion Ossicular in CSOM (Chronic Suppurative Otitis Media) Patients with Cholesteatoma in Dr. Mohammad Hoesin General Hospital Palembang

Background: Chronic suppurative otitis media (CSOM) is inflammation of the middle ear mucosa and mastoid space more than 2 months characterized by perforation of the tympanic membrane and continuous or intermittent discharge from the ear canal. CSOM with cholesteatoma is characterized by perforation that is located marginally or attic with cause destruction ossicle and often causes dangerous complications. This study was aimed to determine the correlation between cholesteatoma stadium among CSOM patients with cholesteatoma in RSUP Dr. Mohammad Hoesin Palembang. Methods: Observational research using a cross sectional design. The data were collected using medical record on 70 subjects with a diagnosis of CSOM with cholesteatoma who underwent mastoidectomy surgery at RSUP Dr. Mohammad Hoesin Hospital Palembang for the period of January 2018 to June 2021. Results: From 70 samples conducted in the study, degree of erosion ossicular in CSOM with cholesteatoma with highest group type D with MERI index score 4 in 34 patients (48,6%). There was a strong positive correlation between degree of erosion ossicular based on MERI index score and cholesteatoma stadium based on Bluestone (p<0.005, R=0.655) From the linear regression test, the most influential in causing degree of erosion ossicular in CSOM with cholesteatoma were tympanic perforation type, granulation and cholesteatoma stadium. Conclusions: There is a significant relationship between degree of erosion ossicular based on MERI index score and cholesteatoma stadium based on Bluestone.
