  1. There were 101 patients with gross abnormalities in their initial sinus X-ray. Positive cultures were obtained in 84 patients, with 140 different types of microorganisms (MOs). Columns 3 and 4 show positive results of the same microorganisms (MOs) cultured from tracheal aspirate and blood, cultured in the period between 24 hours before and 48 hours after sinus drainage.
