Quantitative bacteriology in adenoid tissue.

H C Pillsbury, J F Kveton, C T Sasaki

    Summary

    Bacterial infection in adenoids is common in children with recurrent ear infections. Adenoidectomy may be beneficial for recurrent suppurative and serous otitis media unresponsive to medical treatment.

    Area of Science:

    • Otolaryngology
    • Pediatric Infectious Diseases
    • Microbiology

    Background:

    • The indications for adenoidectomy are debated, particularly for recurrent otitis media.
    • Previous studies correlating nasopharyngeal and middle ear fluid cultures have yielded inconclusive results.

    Purpose of the Study:

    • To quantitatively assess bacterial levels in adenoid tissue.
    • To determine the association between bacterial infection in adenoids and different clinical indications for adenoidectomy.

    Main Methods:

    • Quantitative bacteriologic analysis of aerobic and anaerobic bacteria per gram of adenoid tissue.
    • Analysis of 48 patients undergoing adenoidectomy for nasal obstruction, chronic serous otitis media, or recurrent suppurative and serous otitis media.

    Main Results:

    • A high prevalence of bacterial infection (greater than 10^5 organisms/gm) was found in 83% of patients with recurrent suppurative and serous otitis media.
    • Only 15% of patients with nasal obstruction or chronic serous otitis media had infected adenoids.
    • Adenoid size, measured radiographically, did not correlate with the presence of infection.

    Conclusions:

    • Adenoidectomy should be considered for recurrent suppurative and serous otitis media unresponsive to medical therapy.
    • Infected adenoids are significantly associated with recurrent suppurative and serous otitis media.
    • Quantitative bacteriologic assessment of adenoid tissue is crucial for determining infection prevalence.
