Abstract
Background: Sinonasal disease affects a wide range of population including broad spectrum of
diseases both inflammatory conditions, congenital and neoplastic. Since their clinical assessment
is fraught by the surrounding bony structures; diagnostic radiology is of paramount importance.
This study is aimed at assessing the CT patterns of sinonasal pathologies which is the first study
to the best of our knowledge at Tikur Anbessa Specialized Hospital and in Ethiopia.
Objective: To assess computerized tomography patterns of sinonasal pathologies and patterns
of histopathologic findings at Tikur Anbessa Specialized Hospital.
Methods: Institutional based retrospective cross-sectional study was carried out at Tikur
Anbessa Specialized Hospital department of radiology. A non-probability convenience sampling
technique was employed to include all patients imaged at radiology department for sinonasal
diseases during the study period. Data was collected from medical record books and imaging
archive system to see the imaging reports of patients’ images from November 2019 – July 2021,
using structured data extraction template. The date was collected from June to August 2021. Data
was entered and analyzed using SPSS 26 statistical software. Ethical clearance was obtained
from Ethical Review Committee of the Department of Radiology at Addis Ababa University.
Result: A total of 102 patients were included during the study period of which 64(62.7% were
males and 38(37.3%) were females with age range of 1 day up to 83 yrs. The mean age was 30.7
+ 20.9 years and median age 27.5 years. The most common presentations were nasal discharge
52(50.9 %), and nasal blockage accounting 42(41.2%) Inflammatory etiology is the most
common finding accounting 47.1% (N=48) of the cases and malignant masses is the second most
common category which accounted 28(27.4 %) of the cases. From those having histology the
majority are malignant 25(71.4% N=35).
Conclusion: In this study malignant sinonasal pathologies are common next to inflammatory
causes. All choanal atresia cases were bilateral. Further prospective study with large number of
participants is recommended as this institutional based retrospective study in tertiary center may
not represent the general population.
