Diseases of the nose and paranasal sinuses have a significant impact on the patient's functional and structural aspects. They affect all age groups and both sexes. Due to its proximity to vital structures, diseases of the nose and paranasal sinuses sometimes lead to very grave prognoses. This was a retrospective study done in one of central India's largest tertiary care centers. We studied 227 cases of sinonasal masses in both the non-neoplastic and neoplastic categories. Clinicopathological characteristics of masses were analyzed with the help of clinical and imaging findings and subsequently confirmed by tissue diagnosis. The mean age of presentation was 45.5 years, with a male-to-female ratio of 1.25:1. Most of our patients were from lower-middle socioeconomic groups with educational qualifications below the 10th standard. Nasal obstruction was the most common symptom. A computed tomography scan was the preferred radiological investigation. Sinonasal undifferentiated carcinoma was the most common variant of malignancy, with a total number of six out of 22 (27%). The evaluation of sinonasal masses should be carried out systematically and meticulously. Since the initial presentation of most of the diseases of the nose and paranasal sinuses is the same, a proper clinical, radiological, and tissue diagnosis should be carried out to avoid causing malignant lesions.
