title: [The bacteria isolated from middle nasal meatus and ethmoid sinus of chronic naso sinusitis patients and their correlationship].
abstract: OBJECTIVE
  To explore the bacteria isolated from middle nasal meatus and ethmoid sinuses of chronic naso sinusitis patients and their correlationship.
  
  
  METHODS
  Patients with chronic naso sinusitis were selected to performed the functional nose endoscopy in order to obtain the sample with disinfection cotton. All the samples were cultured aerobically and anaerobically, separately.
  
  
  RESULTS
  In 120 samples of chronic naso sinusitis patients, 2 section of 18 samples (15%) showed the same kinds of bacteria culture positive; and 2 section of 9 samples showed different kinds of bacteria, 24 samples showed culture positive only in the samples from middle nasal meatus; and 12 samples showed culture positive only in the samples from ethmoid sinuses. The positive rate of isolation was 42.5% in middle nasal meatus and 32.5% in ethmoid sinuses. The positive rate of aerobe was 39.2% in middle nasal meatus, and 22.5% in ethmoid sinuses. The positive rate of anaerobe was 12.5% in middle nasal meatus and in ethmoid sinuses.
  
  
  CONCLUSIONS
  The positive rate of isolation was not high in the sample with disinfection cotton of chronic naso sinusitis patients. The correlationship of bacterium between the middle nasal meatus and ethmoid sinuses is little.
