Abstract:
Objective To assess the dynamic changes of bacteria culture of patients with chronic suppurative otitis media (CSOM ) preoperative ,intraoperative ,and postoperative the mastoidectomy .Methods Secretions or tissues in 86 CSOM patients were collected for bacterial culture and drug sensitivity tests ,and analyzed the rusults between cholesteatoma group and nonchol-esteatoma group .Results Hospitalized CSOM patients with positive culture rates preoperatively ,intraoperatively and postopera-tively were 75 .6% ,41 .9% and 1 .2% respectively ;Before the mastoidectomy ,positive bacteria ,positive fungus and no pathogenic bacteria were found correspondingly 49 .1% ,25 .0% and 28 .6% of positive bacteria during the surgery .Culture positive rates be-tween the cholesteatoma group and noncholesteatoma group were significantly different intraoperatively (P<0 .05);while during in-traoperative samples ,no significant differences of positive rates were found between pyogenic fluids and tissues ,as well as tissues of mastoid tympanic antrum area and tympanic antrum entrance area (P>0 .05) .Different bacteria showed different drug sensitivity results .Conclusion Intraoperative bacteriological results shows the different bacteria and drug sensitivity from the preoperative bacteriological results ;CSOM patients with cholesteatoma are more likely to develop bacteria ;it is necessary to carry out dynamic detection on bacterial culture and drug sensitivity tests before ,during and after the surgery .
