Microbiology of Chronic Maxillary Sinusitis

Abstract

Objective: To know the incidence of microorganisms present in culture of maxillary sinus
secretion in patients of chronic maxillary sinusitis..
Methods: We selected 86 patients diagnosed with chronic maxillary sinusitis for our cross
sectional study. Ages of patients were ranging from 20y to 55y.Mean age was 34 years. All
patients with diagnosis of chronic maxillary sinusitis were included in this study. In all 86 patients
proof puncture done through Lichwitz trocar and cannula and sinus secretion was collected for
culture.
Results: In our study we collected sinus aspiration from 86 patients. We found 78 (90.7 % )
patients were positive for bacterial infection and 8 (9.3% ) patients were negative of any bacterial
infection. In our study 38 (44%) patients were suffering from aerobic infection while 20 ( 23.25 %)
were suffering from anaerobic infection. 20 (20.25%) patients were suffering from mixed bacterial
infection. Among aerobes , staphylococcus aureus was the most common bacteria isolated from
sinus secretion of 9 (10.4%) patients . Almostone quarter patients were suffering from anaerobic
bacterial infection. Twenty patients (23.25 %) were suffering from both aerobic and anaerobic
infections .
Conclusions: Chronic maxillary sinusitis is polymicrobial pathology. Various aerobes and
anaerobes and mixed organisms are involved in its pathophysiology.
