Radioactive seed implantation combined with prosthesis denture in treatment of oral and maxillofacial malignancy.

We sought to evaluate the effect of (125)I radioactive seed implantation combined with prosthesis denture on the treatment of oral and maxillofacial malignancy. For this purpose, 10 patients with glandule palatine malignancy were selected and subjected to the treatment plan of radioactive seed implantation during CT examination. All patients were treated as follow. The tumor tissues were extracted first. After 2 weeks, radioactive seeds were implanted in the palatine tissue and the prosthesis denture was made and worn for the tissue defect. Several radioactive seeds were still embedded in the tissue surface of the prosthesis at the same time; 24-36 seeds (average: 28) were used for each patient. All patients were followed up for 3-16 months and the results were evaluated. We found no tumor recurrence or metastasis around the target area in all patients. Significant improvement was shown in terms of speech, mastication, and facial appearance in all cases. Therefore, we concluded that in patients with glandule palatine malignancy, tumorectomy followed by radioactive seed implantation and prosthesis denture are effective for preventing the recurrence and metastasis of malignancy and improving the quality of life.
