Dr. Vinoth Manimaran OBJECTIVE-To investigate the microbial prole that can cause early and late surgical site infections (SSI's) in those who underwent cortical mastoidectomy in order to facilitate prevention and morbidities associated with the same. METHODS- It's a clinical audit (observational study). Case records of 40 patients who developed secondary infection were evaluated and divided into two groups. Group A, patient who developed early SSI's i.e, within 1 month following surgery and group B, those who developed late SSI's i.e, after 1 month following surgery. RESULTS- Total of 200 cases who underwent cortical mastoidectomy during Jan 2016-jan 2019; 40 patients developed secondary infections following cortical mastoidectomy were included in the study, 14(35%) patients developed early SSI's and were categorized into group A. 26 (65%) patients developed late SSI's were categorized into group B. Most commonly isolated organism in both groups pre and postoperatively was Pseudomonas species followed by Staphylococcus and persistence of microbe pre and post operatively in both groups was identied as Pseudomonas. CONCLUSIONPseudomonas aeruginosa was found to be the most common bacterial isolate in patients with SSI's following cortical mastoidectomy. It was also found, pseudomonas as most common microbial isolate preoperatively also results in persistence of disease post-surgery (both in Early and Late SSI's). Staphylococcus aureus was the second most common bacterial isolate and the commonest gram positive isolate found in the ear swabs both preoperatively and postoperatively. Thus this datas highlights the need for a specic SSI surveillance and to check for other parameters like immunological status of the patient in otological surgeries
