Abstract
Introduction: Sino-nasal tumors, a diverse group of neoplasms affecting the nasal cavity and paranasal sinuses, present varying clinical and demographic characteristics. This study aimed to assess the frequency of malignancy in sino-nasal tumors concerning age and gender. Methods: This cross-sectional observational study was conducted at the ENT and Head-Neck Surgery department, Rajshahi Medical College Hospital, Rajshahi, from June 2014 to November 2014. A total of 60 patients presenting with sinonasal tumors were selected as study subjects by purposive sampling technique. Data analysis was done by Statistical Package for Social Sciences (SPSS) version 20.0. A descriptive method was adopted. Result: The highest percentage falls within the 21-30 and 51-60 age groups, each comprising 20%. Males are the majority, with a male-to-female ratio of 3.3:1. The most common symptoms are nasal obstruction (93.33%) and loss of smell (70%). Most cases (93.33%) are benign, with only 6.67% being malignant, predominantly in the older age groups (51-60 and 61-70). Among the malignant cases, 75% are male, giving a male-to-female malignancy ratio of 3:1. Conclusion: This study reveals that sino-nasal tumors are predominantly benign, with malignancies primarily found in patients over 50, particularly males. The strong male predominance in malignant cases aligns with known occupational and lifestyle risk factors. These findings suggest that age and gender are significant factors in malignancy risk for sino-nasal tumors, highlighting the need for focused screening and preventive measures in older male populations who may be at higher risk
