소아 만성 상악동염의 세균학적 고찰

초록

Background and Objectives：Problems with antibiotic susceptibility have recently been raised in the treatment of paranasalsinusitis. Therefore, well-established antimicrobial policy is needed. Samples collected in children who have sinusitis can beuseful to monitor the evolution of resistance. However, relatively a little is known about the maxillary sinus flora in childrenwith chronic sinusitis. This study aims to get a better insight into the maxillary sinus flora and its resistance. Subjects andMethod：Maxillary sinus samples were obtained through inferior meatal puncture from 120 children with history of chronicsinusitis, who have undergone adenoidectomy or adenotonsillectomy. Samples were sent to the laboratory for bacterial culturesand antibiotics sensitivity tests. Results：Organisms were isolated from 142 sinuses (59.0%) of 240 sinus culture, and 98sinuses (41.0%) were sterile. Among the 142 sinuses, 97 sinuses have single strain, and 45 sinuses have mixed strains. Most recoveredorganisms were gram (+) aerobes. Among the gram (+) aerobes, Staphylococcus aureus strains in 41 strains (17.1%),-hemolytic Streptococcus in 42 strains (17.5%), coagulase negative Staphylococcusin 15 strains (6.3%) were the commonlyencountered organism. In an antibiotic sensitivity test for gram (+) bacteria, Vancomycin and Teicoplanin showed sensitivityover 95%. Conclusion：Most isolated organisms were Staphylococcus aureus and -hemolytic Streptococcus. These organismsshowed increased resistance to previously used antibiotics, as compared with the result of similar study carried 18 years ago.(Korean J Otolaryngol 2006;49:499-503)
