Int roduction and aims: Balloon sinuplasty has been the object of recent discussions and papers. It is believed that the use of these tools can bring benefits, when compared with traditional endoscopic sinus surgery. Although there already are papers on the efficacy of this new instrument in the literature, there is no study in our country with a series of cases and follow-up of patients undergoing sinuplasty. Our study aims to review the information of 10 patients who underwent balloon sinuplasty, alone or in combination, discussing the indications, complementary therapy and follow up evaluation. Method: retrospective study.
