Background: This study aimed to evaluate paranasal sinusitis disease and determine if there is a relationship between the
anatomical variation of sinusitis based on the age and gender of the patient and, if so, to identify the most affected demographic group.
Methods and Results: This study included 130 patients (76 men and 54 women with ages ranging from 18 years to 75
years) diagnosed with PNS disease and was conducted in the Radiology Department of King Abdelaziz Specialist Hospital and
King Faisal Hospital (Taif city, Saudi Arabia) from January 1 2021 to January 31 2022. The evaluation of sinusitis was conducted
using multidetector computed tomography (MDCT). The clinical symptoms included 70% cases of nasal obstruction, 53% cases
of headache, 28.5% cases of nasal discharge, 17.7% cases of facial pain, and 3.1% cases of general malaise. The types of sinusitis
included maxillary sinusitis (88.5%), sphenoid sinusitis (28.5%), ethmoid sinusitis (43.8%), and frontal sinusitis (23.5%). The
study found no significant anatomical variation of sinuses based on age and gender (P>0.05).
Conclusion: An evaluation of paranasal sinusitis disease using an MDCT scan shows that there are no gender or age-related
differences in the prevalence of the disease. Moreover, the study demonstrates that there is no significant anatomical variation of
sinuses based on age and gender.(
