Objective: The feasibility and clinical effect of maxillary sinus neoplasms treated by maxillofacial prosthesis immediately after maxillectomy was under discussion. Methods: 13 patients with T3-4a N0 M0 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.

Background: Parotid gland tumors are a frequent to establish the sensitivity, specificity, and accuracy of fine-needle aspiration (FNA), for distinguishing benign from malignant lesions in the parotid gland we carried out this study. Moreover we studied the epidemiological facts of the parotid masses. Methods: Retrospective review of all the patients who underwent a parotidectomy in our department during the last five years and in which a FNA was performed as a diagnostic method of parotid mass, were studied in order to compare the citologic and histologic findings after excision. Results: Sex and age distribution of the parotid gland tumors varies in relation to the histological results. The most prevalent tumor was the pleomorphic adenoma followed by Whartin tumor. A 25% were malignant and a 75% benign. The citological findings match with histological results in 70.96% of the cases. The FNA allows us to exclude malignancy in a 94.8% of all cases but misdiagnose a 5.2% of malignant masses. Conclusions: We found parotid gland FNA study to be a safe and accurate technique to rule out malignancy in parotid gland masses. No relevant side effects were observed. The global accuracy of the parotid gland FNA is above 70% in our study. So we do recommend the FNA as a part of the diagnostic protocol in parotid gland masses.

There is controversy about the morbidity and complications that the radial flap donor site has, and some authors suggest the use of other flaps. We have studied the frequency of complications at the donor site in 20 cases. Material and methods: The study sample includes all patients who underwent surgery with radial flap reconstruction between January 2006 and December 2010 (n 20) in the Department of Oral and Maxillofacial Surgery Hospital Gregorio Mara˜nón. We analyze the immediate and long-term complications. Of these 7 died and 3 patients had not been followed developmentally. Ten patients were interviewed with a follow-up between 6 months and five years evaluating the sensitivity epicritic, flexion and extension of the wrist and thumb opposition. The flap design was always based on a negative Allen test, and was used as far as possible the non dominant forearm. The resulting skin defect was covered with a dermo-epidermal graft. The forearm was splinted for a period of 10 days. Results: We observed 1 case of Mucor infection in the donor site, the patient died in the intensive care unit due to respiratory complications. The remaining complications were minor, such as tendon exposure in two cases with a favorable outcome with conservative treatment. The motor disturbances and sensitivity epicritic do not limit the quality of daily life. Conclusions: The radial fasciocutaneous flap is a secure reconstructive due to its low complications, most of them compatible with everyday life.
