Objective: To properly understand the bacterial distribution and susceptibility to antibiotics in the sinus of nasal sinusitis.
Method: The mucosal and secretion in sinus were taken from 135 patients who suffered with single nasal sinusitis, by functional endoscopic sinus surgery, were cultured for bacteria. Meanwhile the antimicrobial susceptibility was determined for ordinary antibiotics.
Result: The bacterial growth was present in 88.15% of cases, mixed bacterial growth was present in 52.10% of all bacterial, anaerobe growth was present in 39.06% of all bacteria, the susceptibility to penicillin was in 53.12% of all bacteria and cefaolin was in 87.50%. The susceptibility to metronidazole was in 94.67% of all anaerobes.
Conclusion: We think the method that penicillin in combination with streptomycin and metronidazole, sufameth oxazole united with metronidazole, cefaolin added metronidazole were effective in nasal sinusitis treatment before the antimicrobial susceptive examination had been done.
