Abstract

Abstract: Objective: To investigate the efficacy and prognosis of decompression combined with curettage for unicystic ameloblastoma. Methods: 20 cases of unicystic ameloblastoma were treated with decompression. The cyst plug with soft liner thermosetting resin was used to keep the wound open and a second stage curettage was performed. The changes of tumor cavity were observed after the operation. Results: Patient imaging showed that the lesion range was significantly reduced, and the anatomy of the lesion area was close to normal. The tumor cavity decreased by 28.66% on average 3 months after operation, and decreased by 58.51% on average 6 months, decreased by 79.33% on average 12 months. After the surgery, the sizes of the tumor cavity shrank, all these had statistical significance (P＜0.05). Then 6 months later, the bone mineral densities at coronal and sagittal and horizontal respectively were 371.32 Hu, 361.74 Hu, and 384.71 Hu. Followed-up 12 months, the bone mineral densities increased to 517.64 Hu, 523.22 Hu, and 521.05 Hu (P＜0.05). The second stage curettage was performed 12 to 24 months after operation. No recurrence of tumor was observed in the 3 to 5 years of follow up. Conclusion: It is an effective method for the treatment of unicystic ameloblastoma by decompression combined with curettage. And the cyst plug with soft liner thermosetting resin was used to keep the wound open. Second stage curettage was performed when the changes of tumor cavity were not obvious.
