title: [Experimental study on intramaxillary injection of fosfomycin. Effects of fosfomycin on experimental acute sinusitis in rabbits].
abstract: We studied effects of intramaxillary injection of fosfomycin (FOM) on experimental sinusitis in rabbits. The experimental sinusitis was induced by intramaxillary injection of Staphylococcus aureus to rabbits for 3 successive days. 1. 0.5, 1, 3 or 5% FOM with saline as a control was instilled into the maxillary sinus and the maxillary sinus mucosa were examined macroscopically and light and electron microscopically. 3% and 5% FOM suppressed the damage of mucosa macroscopically and scanning electron microscopically. 2. After administration of 3% FOM and saline twice a week, the maxillary sinus mucosa was examined macroscopically and light and electron microscopically. The maxillary sinus injected with 3% FOM showed almost normal mucosa after 2 weeks while that injected with saline showed severe mucosal damage. S. aureus were decreased by 3% FOM injection and not found in the maxillary sinus in a week. The results indicate that intramaxillary injection of FOM is very effective in the treatment of sinusitis.
