Abstract
YAMIK sinus catheter (YAMIK) which is physical therapeutic device for sinusitis was used to evaluate the efficacy of drainage of effusion in the paranasal sinuses (PNS). This method was used once a week for 3 consecutive weeks to evacuate pathological secretion from PNS through natural ostia without topical or general medication. Subjective symptoms were improved. X-ray findings showed significantly improved shadows compared with those before this therapy. The saccharin time for measurement of mucociliary transport rate was shortened significantly by this treatment.
PNS effusion of chronic sinusitis cases, in which no antibiotics was medicated at least for one week, was obtained by YAMIK was cultured aerobically. We classified these cases into 2 groups depending on the result of this bacteriological examination; in Group 1 apparent pathogenic bacteria were isolated, in Group 2 nonpathogenic bacteria were isolated or no bacteria grew. In Group 1 improved-case ratio was only about 50%, on the other hand in Group 2 it was about70%.
The incidence of H. influenzae in PNS effusion was 9.1%. The incidence of P 6 gene DNA of H. influenzae detected by PCR-hybridization was 27.3%.
This study shows that drainage of effusion is quite effective factor in the therapy of sinusitis and H. influenzae plays an important role in upper respiratory inflammation.
