ABSTRACT
Tuberculosis remains a real public health problem in Tunisia. Extra-pulmonary localizations account for 20 to 30% of tuberculosis disease, dominated by the node, osseous and urogenital localization. The authors present three cases of extra-pulmonary tuberculosis concerning the maxillary sinuses which represents an unusual localization of the disease. They were a man and 2 women old respectively of 30, 65 and 36 years. The main symptoms were dominated by nasal obstruction, posterior throwing and dental pains. All the patients profited from a complete clinical exam. A tomodensitometry exam was performed for the 3 patients. A maxillary sinus biopsy with anatomopathologic exam was made and had confirmed tuberculosis in all the cases. The three patients were treated with anti-tuberculosis quadruples for 2 months then double for 8-9 months and the evolution was good in all the cases after a 22 month retreat
