Abstract

Background: This was a comparative microbial study of pre and postoperative mastoidectomy. The aim of the present study was to evaluate various causes responsible for discharging mastoid cavity.

Methods: Total of 160 patients of which 100 cases were of preoperative group and 60 cases were postoperative group included in the study.

Results: Mono infection was seen in 95% and 86.7% in pre and postoperative cases respectively; where as 5% of preoperative and 13.3% of postoperative cases were diinfections. Pseudomonas (32%) was found in highest number followed by Staphylococcus aureus (16%), Klebsiella spp. (16%), Escherichia coli (15%), Proteus mirabilis (14%), Aspergillus fumigatus (2%), Candida (1%), and Cladosporium (1%) in preoperative cases. In postoperative cases, 46.7% of Pseudomonas spp, followed by 16.5% Staphylococcus, 16.7% Klebsiella spp, 11.7% Proteus mirabilis, 10% Escherichia coli, 8.3% Aspergillus fumigatus and 5% Candida were isolated.

Conclusions: Multiple factors were responsible for otorhhoea with significant contribution from the microbes.
