Introduction: The postoperative drainage and the postoperative bleeding from maxillary sinus cavity have been controled after functional sinus surgery. It has usually been done using the band of iodize gauze squeezed through the temporary opening in the vestibular mucosa or through the inferior meatal antrostomy.
The aim of this study was to present the use of balloon-catheter in maxillary sinus surgery intendend for control of postoperative drainage and bleeding.
Case report: Balloon-catheter was used in one female who was treated for anaemia after chemotherapy and with allergy to iodine. It was inserted into the sinus cavity through the temporary inferior meatal antrostomy and removed five days after surgery without any postoperative discomforts and complications especial-ly in this risk group of patiens.
