Özet
BACKGROUND & AIM Sinonasal tumors are rare and histologically heterogeneous lesions ranging from benign papillomas to aggressive malignancies. Large single-center series remain valuable for understanding treatment patterns and outcomes.To evaluate the clinicopathological spectrum, management approaches, and outcomes of sinonasal tumors treated over a 10-year period at a tertiary referral center. MATERIAL & METHODS A retrospective review was performed of patients treated for sinonasal tumors between 2016 and 2026. Patients without adequate follow-up and benign osseous lesions were excluded. Demographic data, histopathology, tumor behavior, surgical approach, adjuvant treatment, recurrence, and survival outcomes were analyzed. Tumors were classified as benign, borderline/intermediate, or malignant. RESULTS A total of 167 patients were included.Mean age was 52 years (8–98) and 60% were male. Overall,103 tumors (61.7%) were benign,6 (3.6%) borderline/intermediate and 58 (34.7%) malignant.Patients with benign tumors were younger than those with malignant tumors (49-56 years),with male predominance in both groups(63% vs 58%).The most common benign diagnosis was Schneiderian papilloma(n=67), followed by vascular tumors. Benign lesions were mainly treated endoscopically with excellent disease control.Malignant tumors were mainly epithelial malignancies (n=29), followed by mucosal melanoma (n=8), olfactory neuroblastoma (n=5), and mesenchymal/sarcomatous tumors (n=16).Among malignant cases, 46.6% received radiotherapy, 32.8% chemotherapy, and 10.3% underwent neck dissection.Recurrence and mortality were higher in the malignant group, with mucosal melanoma showing the poorest outcomes. Open or combined approaches decreased from 45% (2016–2020) to 25% after 2021,reflecting the increasing predominance of endoscopic surgery. Open surgery remained necessary for extensive malignancies with orbital, premaxillary soft tissue, nasal bone, or frontal bone involvement
CONCLUSIONS Sinonasal tumors show marked pathological heterogeneity, with benign lesions predominating but a substantial malignant burden in tertiary practice. Over the past decade, management shifted strongly toward endoscopic surgery, while advanced malignant tumors continued to require aggressive multidisciplinary treatment.
