Abstract: Chronic suppurative otitis media (CSOM), is defined as chronic inflammation of the middle ear and mastoid cavity, which is characterized by recurrent ear discharge or otorrhoea through perforation of the tympanic membrane. The purpose of this study was to prove that there was a difference in ABG values between intact and destroyed ossicular chains in CSOM patients without cholesteatoma. The type of research used is analytic observational with a cross sectional research design. Data obtained from secondary data in the form of medical records at URJ ENT-KL Otology division of RSUD Dr. Soetomo. The ABG value was obtained through a pure tone audiometry examination carried out at the URJ ENT-KL neuro-otology division by competent personnel. Pathology of the tympanic cavity was found in the form of granulation tissue in 60 patients (73.2%) without granulation in 22 patients (26.8%). Based on the type of perforation, central perforation was found in 26 patients (31.7%), sub-total perforation in 34 patients (41.5%) and total perforation in 22 patients (26.8%). Intact ossicular chains were found in 62 patients (75.6%) while destruction in 20 patients (24.4%). Based on the results of the independent t test, the value of p = 0.002 was obtained. There is a significant difference in the value of the air bone gap between intact ossicular chains and destruction in CSOM patients without cholesteatoma at a frequency of 500, 1000 and 4000 Hz but there is no difference at a frequency of 1000 Hz.
