Abstract

Objective: To analyze the method and effect of reconstruction of the orbital floor defect with preserved orbital contents after advanced maxillary sinus cancer resection. Methods: Thirty-three patients of T3/T4 stage maxillary sinus cancer with orbital invasion who were treated in Shandong Provincial Hospital from January 2010 to October 2016 were retrospectively analyzed, including 20 males and 13 females, aged from 12 to 80 years old. Patients were treated with appropriate surgical methods according to their clinical manifestation, imaging finding, invasion range, preoperative and intraoperative pathology. Surgical approaches such as maxillectomy, expanded maxillectomy and superstructure maxillectomy were used for patients with Medpor orbit floor repairment. Patients were followed up regularly after surgery, and the surgical efficacy was discussed by descriptive statistical method. Results: Of those 33 cases, 19 were squamous cell carcinoma, 8 were adenoid cystic carcinoma, 5 were inverted papilloma malignant transformation, and 1 was myoepithelial carcinoma in our study. After tumor resection and orbital floor repair, the orbital contents and eyeball function of all patients remained intact. During follow-up time ranged from 3 to 8 years, a total of 6 patients relapsed at 3 years and died of ineffective treatment. The survival rate was 81.8% (27/33). Conclusion: Tumor resection and Medpor orbital floor repair in maxillary sinus cancer patients with orbital invasion can preserve the function of the eyeball well, greatly improve the quality of patient's life.
