ABSTRACT
The goal of this study is to evaluate the role of computed tomography scan in the diagnosis of sinuses diseases. This was a cross-sectional study design, conducted in different hospitals and clinical centers at Khartoum State. Totally 26 males and 24 females aged ranges from 10 to 70 years old with different symptoms were selected, axial and direct coronal cuts were done for all cases. The study revealed that most patients were affected in the both sides, with a history of sinuses diseases in their families, maxillary sinuses are the most affected area, and most patients suffer from headache. Chronic and fungal sinusitis the sensitivity of the coronal view was [77%, 61%, and 61%] respectively compared to axial that was [22%, 36%, and 38%] respectively In the nasal polyp and granulomatous diseases, the efficiency of the coronal view was [62% and 65%] respectively, while in axial was [37% and 34%] respectively. In benign and malignant tumor the efficiency of coronal was 57% and 32% respectively, while in the axial view was [42% and 21%] respectively. This study concluded that the two image planes are performed together and used as an essential technique of peripheral nerve stimulation
