Rhinoscleroma is a chronic specific granulomatous inflammatory condition that has an affinityto the mucosa of the upper respiratory tract. Involvement of maxillary antrum is said to be very uncommon. In the present study antroscopy was performed in 20 patients with rhinoscleroma to find out the type, nature and site of the lesion in the maxillary antrum. The maxillary antrum was involved in 60 per cent of cases with rhinoscleroma. The lesions occurred in the form of atrophic changes, granuloma, and the fibrotic thick healed stage. The anterior–inferior part and medial wall of the antrum are found to be more commonly affected. It is suggested that involvement of maxillary antrum in scleroma may act as a reservoir of infection and such patients may therefore take a longer time to respond to antibiotic therapy.
