Abstract: Background: Paranasal sinuses are air-filled cavities found in the facial bones. The pathological conditions of these sinuses ranges from sinusitis to neoplasm.The aim of this study was to evaluate the computed tomography (CT) findings in paranasal sinus pathologies among patients referred for paranasal sinuses CT scan in Rivers State, Nigeria. Materials and Methods: The examinations were performed using GE multi-slice helical machines in axial and coronal sections with standard protocols and parameters. Retrospective study design was adopted for this study. A convenience sample size of 230 record’s of patients that underwent CT scan for paranasal sinus pathology between January 2012 and March, 2018 was selected from the archive of the selected study centers randomly. Data were obtained using structured proforma. The data were analysed using descriptive statistics. Results: Out of 230 cases studied, sinusitis (41.74, n=96) was the most common pathology and the least was osteoma (1.74%, n=4). In 85% (n=188) of the cases, more than one sinus was involved. Maxillary sinus was involved in 89.6 % (n=206) and the least was sphenoid sinuses 26.42% (n=96).The most commonly involved areas by PNS pathologies extension in this study was soft tissues (58.60%, n=135) and the least was lacrimal gland (7.83%, n=18). Most common age group affected by the pathologies was 16-30 years age group (40%, n=92) and the least were within age group 0-15 years (3.48%, n=8). In this study, paranasal sinus pathologies were more in males (58.70%, n=135) compared to female population (41.3%, n=95). Conclusion:The commonest paranasal sinuses pathology in this study was sinusitis. Maxillary sinuses were the most commonly affected sinus. Majority of the PNS pathologies were within the age group 16-30 years of age while the least were within the age group 0-15 years. Male preponderance was noted.
