Immediate rehabilitation by hollow denture obturator prosthesis after maxillectomy for the patients of maxillary sinus malignant tumor

Objective: The feasibility and clinical effect of maxillary sinus neoplasms treated by maxillofacial prosthesis immediately after maxillectomy was under discussion.

Methods: 13 patients with T 3-4a N 0 M 0 maxillary neoplasm were treated by maxilloectomy and a hollow denture obturator prosthesis fit on immediately. According to the nasal sinus 3D-CT, the Simulating surgical operation with Surgicare 5.0 software and the 3D stereoscopic prototype was constructed before the surgery. The prosthesis was made quickly and precisely by methacrylate resins according to this model with supplementary tooth at the bottom before the surgery. In the surgery, the prosthesis was installed instantly after maxillectomy. The permanent prosthesis made of titanium framework and methacrylate resins was replaced 6 months after the surgery.

Results: The prosthesis was installed immediately and repaired accurately after maxillectomy for each of the 13 patients. The results of questionnaires showed that all the patients were satisfied with the retention of prostheses, the improvement of appearance, and the symptom of water choking and speech. 11 of the 13 patients installed the permanent prosthesis, 6 months after the surgery.

Conclusions: The precise manufacture and instant repair of maxillary denture prosthesis after maxilloectomy had improved survival quality of the patients.
