    Abstract:
    OBJECTIVE: The purpose of the study was to examine the oncological and functional outcomes of multimodality therapy for patients with advanced malignant maxillary sinus tumors that invaded the orbit. STUDY DESIGN: Retrospective study. METHODS: The medical records of 26 patients with orbital invasion were retrospectively analyzed. The patient group consisted of 16 men and 10 women, with a median age of 58 years. The mean follow-up period was 73 months. The most common disease was squamous cell carcinoma. Seven patients had nodal disease. All patients underwent simultaneous combined therapy consisting of conservative surgery through a sublabial incision, radiotherapy, and regional chemotherapy. Patients with nodal disease were treated with either irradiation or selective neck dissection. RESULTS: The 5- and 10-year overall survival rates were 68% and 51%, respectively. The 5- and 10-year local control rates were 66% and 51%, respectively. Overall survival rates and local control rates were significantly worse in patients with disease other than squamous cell carcinoma. Local control rates were significantly worse in patients with orbital apex disease than in patients without orbital apex disease. All 26 patients, despite orbital involvement, retained their orbital contents. Nineteen of these patients demonstrated adequate ocular function. CONCLUSIONS: Combined therapy with conservative surgery, radiotherapy, and regional chemotherapy is an effective method for local control and preservation of ocular function. However, performing orbital conservation procedure in patients with disease other than squamous cell carcinoma and with orbital apex disease must be considered carefully.
