title: Bacteria in chronic maxillary sinusitis.
abstract: Sixty-one chronically inflamed maxillary sinuses produced 131 bacterial strains from mucosal pieces that were taken during a Caldwell-Luc operation and cultured aerobically and anaerobically. Sinus secretions showed only 62 and nasal secretions 106 bacterial strains. Fourteen mucosal strains, including 11 Haemophilus influenzae, grew heavily. None of 24 mucosal anaerobes showed heavy growth. Of 52 antral mucosae with culturable bacteria, 37 disclosed mixed and 15 pure growth. The bacteriological characteristics of the diseased sinus and the nose did not correlate. The duration or extent of the disease, the macroscopic appearance of the diseased sinus, or the presence or absence of allergy were unrelated to bacteriological findings, except that H influenzae was concentrated in purulent sinuses. Intraoperative culture of antral mucosa seems to give the most reliable picture of the bacteriological condition in chronic maxillary sinusitis.
