Abstract
A series of clinical investigations was carried out on 7 infants with recurrent otitis media. The X-ray study revealed sinusitis in all subjects, though in certain cases no abnormal finding was obtained on rhinoscopic examination. Bacteriologic tests on secretions in the middle meatus were performed in 5 patients. Haemophilus influenzae was depicted in 4 out of the 5 cases. Most of these stocks were resistant to some antibiotics such as AB-PC and CEX. An aerosol treatment with DKB (Dideoxikanamicin B) was done on all 7 subjects. In all patients the recurrence of otitis media ceased, and the pathologic findings in the paranasal sinuses showed improvement in the majority of cases. The importance of detailed examination of the paranasal sinuses in the treatment of otitis media was emphasized.
