The purpose of this study was to assess retrospectively the efficacy of balloon catheter inserted into maxillary sinus via natural ostium on Caldwell-Luc operation. From January 2008 to February 2013, the patients who were diagnosed as nonodontogenic maxillary sinusitis were included. Patency of ostium and thickness to sinus mucosa were examined in preoperative and postoperative computed tomography. Finally 8 patients were included and among them, catheters were inserted in 5 patients, and not in 3. Compared to preoperative state, ostial obstruction was resolved in 3 patients and degree of mucosal thickening was decreased in 4 patients in catheter insertion group. One patient showed increased mucosal thickening, and 2 patients did not showed any change. In the group without balloon catheter, ostial patency was observed in 2 patients preoperatively and 3 postoperatively. Degree of mucosal thickening was not changed in 2 patients and decreased in 1 patient. The patients underwent iliac bone graft to close the lateral window of sinus showed worse prognosis. Also, ostium maintained patency without balloon catheter in all patients with patent ostium preoperatively.
