Microorganisms and Culture and Sensitivity Pattern in Chronic Suppurative Otitis Media in a Tertiary Care Hospital

Abstract

Introduction CSOM is defined as persistent or intermittent infected discharge of more than three months duration through the perforated or non intact tympanic membrane caused by bacteria, fungi and virus resulting in inflammation of mucosal lining that often results in partial or total loss of tympanic membrane and ossicles. The aim of study was to study the current bacteriological profile responsible for the disease. Methods This descriptive cross sectional study was carried out at the department of Ear , Nose and Throat (ENT) and Head and Neck Surgery (HNS) in a tertiary care centre from January 2019 to December 2020. Ethical approval was taken from Institutional Review Committee (Reference number 52/2021). A convenient sampling method was used and data analysis was done in Microsoft Excel . Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. Results There were a total of 324 patients included in the study. The age range was from five to sixty-eight years. Most patients were of the age group below 10 years. There were a total of 178 males and 146 females. The most common organism isolated were Staphylococcus aureus 145 (44.8%) and Psedomonas aeruginosa 86 (26.6%). Conclusions Staphylococcus aureus and Pseudomonas aeruginosa were the most common organisms responsible for chronic suppurative otitis media in our study. Keywords: chronic suppurative otitis media, Staphyllococcus aureus.

Bacteriological Trends of Chronic Mucosal Otitis Media in a Tertiary Care Hospital in the Northern Region of Bangladesh

“…9 In contrast, maximum number of patients in the age group of 6-10 years (41%) were observed by Sharma et al 5 COM generally affects both sexes. In our study, males (56.25%) were more commonly affected than females (43.75%) that reflects slight male predominance (1.4:1) which was in accordance with Shrestha et al 12 and Kazeem et al, 17 but differs from that of Shrestha et al, 18 where females (55.2%) are more than males (44.8%). Male predominance may be due to their more exposed way of life, or it might be simple reflection of overall high male attendance in hospital outpatient department or may be due to increased vulnerability of the male child to organisms and apparently decreased attention to personal hygiene compared to the female counterparts in this environment.…”

“…These findings are in correlation with that of various studies which were carried out in developing countries. 2,7,9,[11][12][13][14][15][16][17] Young children may develop COM due to unhygienic condition and over gathering in school premises. 9 In contrast, maximum number of patients in the age group of 6-10 years (41%) were observed by Sharma et al 5 COM generally affects both sexes.…”

“…found that Pseudomonas is the predominant organism (i.e., 54.43%, 34%, 49%, 38.79% and 38%, respectively), in their studies. On the other hand, Neha et al,1 Shrestha et al,12 Ahmed et al,15 and Samanth et al21 observed that S. aureus is commonest isolate in (i.e., 39.82%, 44.8%56.7%, and 35.0% respectively) in their studies.…”

“…11 Various complications associated with the disease are irreversible local destruction of middle ear structures, facial palsy, serious intracranial and extracranial complications. 12 The assay of the local pattern of infection is essential to establish efficient treatment as the untreated cases can lead to these wide range of complications. 5 This study was undertaken to isolate the present bacteriological trends in the patients suffering from COM.…”
