Abstract :

Objectives: Paranasal Sinusitis is an inflammation of the mucosal lining of the paranasal sinuses. As the mucosa of the sinuses is continuous with that of the nose, rhinosinusitis is a more suitable term. Computerized Tomographic (CT) scan have been used to diagnose chronic rhinosinusitis. The prevanlence of the disease has not been well investigated in the study population. Thus, the aim of this study is to indicate the prevalence of paranasal sinusitis and to determine the most common sinus that is being affected by the disease. Methods: This study is a retrospective study of 326 patient�s radiological CT scan reports which were derived by accessing the report database of the Nnamdi Azikiwe University Teaching Hospital Nnewi, Anama State Nigeria. The level of the statistical significance after analysis was considered at p- value of p<0.05 and at confidence interval of ninety-five percent (95%). Results: This result showed that all the paranasal sinuses cases were susceptible to rhinosinusitis and maxillary sinus with the left side was more infected than the right side. Thus maxillary sinus is the most common sinus to be infected with the prevalence value of 48.47%, followed by ethmoidal sinus of 27.30%, sphenoidal sinus of 23.31% and frontal sinus which is the least value of 13.80%. The most affected age is within 21-30years. Conclusion: This study showed that rhinosinusitis is prevalence amongst the patients presented with ain CT scan, and has no age limit. Advances in knowledge: Computed Tomography plays an effective role to classify and assess PNS that help in management and follow-up.
