Study of Antibiotic Sensitivity of Aural Swab and the Aetiological Factors of Chronic Otitis Media-Active Mucosal Type

Background: Chronic otitis media (COM) refers to chronic inflammation of the muco-periosteal lining of middle ear cleft resulting in ear discharge and deafness. The objective of this study is to evaluate the antibiotic sensitivity and aetiological factors of COM. Methods: This cross-sectional study was conducted from July 2018 to June 2019 for duration of one year among the patients who attended with COM- active mucosal disease at Department of ENT & Head Neck Surgery, Government Medical College Srinagar, India. Total 100 cases were isolated and among them 10 cases had bilateral COM. Aural swab was taken from 110 ears and a predesigned data collection sheet was duly filled up with the information of socioeconomic status of the patient. The laboratory records of every case was systematically organized. The data were analyzed with simple manual analysis using percentage and frequency. Results: About 24% patients were in 31-40 years age group. Out of 100 patients 62% were male. Ear cleaning habit shows, 32% has got the cleaning habit with ear buds. Out of 100 patients 10 had bilateral COM. So out of 110 ears, Culture & sensitivity test viewed that Pseudomonas aeruginosa was the most predominant organism - 41.8% followed by S. aureus- 30.9% Antibiotic sensitivity profile showed 80% cases having sensitivity to Amikacin then Gentamycin-73.3% .Resistant 10 cases showed 100% sensitivity to Tazobactum. Again out of 38 cases of Gram positive organism 78.9% were sensitive to Amoxyclav. 6 resistant cases showed 100% sensitivity to Meropenem. Conclusion: By this study we will be able to make an idea about the aetiological and predisposing factors and antibiotic sensitivity of COM-active mucosal variety.
