AbstractBackground: Postoperative infection following mastoid exploration under strict aseptic conditions and antibiotic coverage postoperative cases of cortical and modified radical mastoidectomy do pose challenging infections. Aim: The present study identifies the organism and antibiotics to which they are sensitive. This measure prevents postoperative permanent disease and discharge and improves the success rate of surgery without complications. Materials and Methods: A total number of 120 patients of mastoid exploration with discharge were the subjects of present study. The study was carried out from Feb 2018 to Feb 2021. Result: Males were 72 who constituted 60% and females were 48 who constituted 40%. Emergency procedures were 85 who constituted 71% and elective procedures were 35 who constituted 29%. 48% (58) were clean surgeries and 52% (62) were clean contaminated surgeries, 109 (91%) of patients showed significant growth and 11 (9%) of patients had no growth. 50% of the patients had culture positivity and duration of surgery was greater than 2 hours. Diabetes is the most common risk factor followed by hypertension. A total of 109 samples showed growth, 114 organisms were isolated. E. coli was the organism which was predominant followed by Staphylococcus aureus. Ampicillin showed maximum resistance followed by ceftazidime. Cefipime and Piperacillin showed least resistance to E.coli. Among 38 isolates, 12 (33%) were ESBL producers. Conclusion: The present study provides information about the incidence of commonest organism E. coli in post operative mastoid exploration to enable treatment of a patient immediately to prevent complications from re- infection.
