Background: Sinonasal neoplasia comprises approximately 3% of all head-and-neck tumors. However, the incidence of these tumors may be greater in some parts of the world including Asia and Africa. Aim and Objective: The study aimed to review the clinical and histopathological pattern of sinonasal neoplasms in Kano, Nigeria. Materials and Methods: The records of patients managed for sinonasal neoplasia at the Department of Otorhinolaryngology, Aminu Kano Teaching Hospital, Kano, Nigeria, over a period of 10 years were reviewed. Information obtained from the case files included demographic characteristics, tumor characteristics, and clinical information. The data obtained were analyzed using SPSS version 23. Results: A total of 245 patients were reviewed with sinonasal neoplasms. Among these, 168 (68.57%) were males, with a sex ratio (M:F) of 2.18:1. The mean age was 40.2 ± 18.9 years. Malignant sinonasal neoplasm constituted 55.92%% of the sinonasal neoplasia, with peak age at the fifth decade. Squamous cell carcinoma was the most common histological subtypes seen in 50.36% of the patients. Inverted papilloma was the most common benign sinonasal neoplasia (42.59%). The most common symptom presented by the patients was nasal obstruction (77.55%), mostly presented within 6 months of onset of symptoms (63.67%), and farmers were the predominant (27.76%). The most common treatment modality was surgical extirpation (54%), and most of the patients presented with Stage IV disease (88%). The site of tumor was found to statistically correlate with the type of tumor among the patients (P ≤ 0.0001), whereas the type of tumor and site of tumor correlated significantly with the duration of symptoms before the presentation. Conclusion: Malignant sinonasal disease is the predominant sinonasal neoplasm in this environment, and most of the patients presented with advanced disease.
