The purpose of the surgical treatment of the frontal sinus cyst is to widen the obstructed naso-frontal sinus duct. In our department during the past 8 years, 15 patients were treated surgically with silicon tube drainage. We made three kinds of tube, type A, B and C. Depending on the intraoperative findings, the silicon tube was cut to fit the naso-frontal duct and sinus. The average intubation period was 46 months. The A type of tube was firmly placed in the naso-frontal duct. The B and C types also did not slip out spontaneously, but were safely removed after surgery. These 3 types of silicon tube have proved useful for the treatment of frontal sinus cysts.
Key words :frontal sinus cysts, silicon tube, surgical treatment
