Multidisciplinary approach to the therapy of chronic sinusitis.

Twenty patients with maxillary sinusitis were treated with cefotetan (1 g, i.m.) twice a day. Samples of blood and maxillary sinus mucous membrane were taken in eight patients 2 h after dosing during the third day of therapy to evaluate drug concentration. Results show the excellent clinical and bacteriological effectiveness of cefotetan, as well as its high tissue penetration.
