Background: Intranasal and paranasal sinus masses are divided into neoplastic and non-neoplastic. This study was designed to evaluate the frequency and histopathology pattern of the nasal and paranasal masses in the otolaryngology department of Shafa Hospital during 2006-2011. Methods: This study was done based on 146 medical records at the ENT department of Shafa Hospital during 6 years from 2006 to 2011, and the tumors were evaluated based on their pathological diagnosis. In this study, in addition to demographic information, disease symptoms and duration, location of the mass, allergy history and profession of the patient, was also recorded. T-test and chi- square were used for analyzing the results. The statistical software used was Excel and SPSS 16. Results: The average age of the patients was 37.8 and 60.3% were male. The most prevalent location for the tumors was the nasal cavity. 88.4% of the masses were benign. Among the inflammatory masses allergic polyps were the most prevalent. Among the benign masses Hemangioma and Inverted papilloma and among the malignant masses, Nasopharyngeal carcinoma and Adenocarcinoma were the most prevalent. The most prevalent symptom in patients was nasal obstruction (91.1%). Conclusion: Most of the tumors of the nasal and sinus cavities occur in the nasal cavity and mainly present with nasal obstructions. Most of these tumors are inflammatory but a percent are malignant and should be paid attention. Keywords: Nasal mass, Paranasal sinus mass, Kerma
