- Abstract: Postoperative maxillary cyst is a late complication that occurs after maxillary sinus radical surgery. The only curative treatment is surgery, and endoscopic fenestration is currently performed in most cases. However, in some cases, it is difficult to form a permanent fenestration. Here, we report a case of postoperative maxillary cyst which was reduced by administration of kumibinroto and could avoid surgery. The case was a 58-year-old man. He received bilateral maxillary sinus radical surgery 40 years ago. He had swelling of his left cheek for half a year and took an antibacterial drug at a nearby doctor, but he was referred to our department because there was no improvement. We diagnosed him with a postoperative maxillary cyst based on CT findings, but it was considered difficult to form a permanent fenestration due to the small contact area between the nasal cavity and the cyst. He refused to puncture from the oral cavity, so we planned endoscopic surgery and administered kumibinroto to him. After 6 weeks, the swelling of the left cheek disappeared. After 12 weeks, CT showed shrinkage of the cyst, and surgery could be avoided. No further cyst shrinkage was observed, and we reduced the dose of kumibinroto after 20 weeks. He is now being followed up.
