Anaerobic infection in chronic maxillary sinusitis.

1) Ten per cent of cases of chronic maxillary sinusitis in a series of 50 cases treated in the ENT department of Dayanand Medical College, Ludhiana, were caused by anaerobic infection. 2) The causative anaerobic micro-organisms encountered were Peptostreptococcus and Clostridium species. 3) Treatment should, therefore, include metronidazole, especially in those cases refractory to conventional antibiotic therapy.
