Radiological and antroscopic study of maxillary antrum in multibacillary leprosy patients.

Sixty consecutive patients having multibacillary leprosy were examined for symptoms of nasal involvement and sinusitis. A complete ENT examination was carried out of all these patients and they were subjected to radiological examination of paranasal sinuses. Radiological abnormalities of maxillary antrum were found in 15 of 20 cases of lepromatous leprosy, 6 of 26 cases of borderline lepromatous and in 14 cases of mid-borderline leprosy. Localized or generalized mucosal thickening was the most common finding, followed by opacity of maxillary antrum. Radiological abnormalities were confirmed by antroscopy, which is the most appropriate technique for making an accurate diagnosis of maxillary antral diseases. Initially, antral involvement may begin with a localized area of mucol erythema, progressing to a typical granuloma formation and ulceration. The antero-inferior part of the antrum was found to be the most commonly affected region.
