Abstract

OBJECTIVES
To illustrate the various causes of Paranasal sinusitis and anatomical variations and assist ENT specialists in visualizing anatomical variations of paranasal sinuses.
METHODOLOGY
 A cross-sectional study was conducted in the Radiology department of Allied Hospital and Faisal Hospital Faisalabad on 50 patients (20-70 years) using TOSHIBA 16 slice helical CT for four months through a convenient sampling technique. Data was collected by Performa and analyzed by SPSS version 22.
RESULTS
Paranasal anatomical variations were found in 30 out of 50 patients. Among the anatomical variable patients, 23 were male, and 7 were female. The most common anatomical variation was Nasal Septum Deviation (28%), while the least common was Agger Nasi Cells (5%). The study found an association between chronic sinusitis and anatomical variations; 22 patients with mild sinusitis were treated with antibiotics, while 8 patients with severe sinusitis were treated with endoscopic sinus surgery.
CONCLUSION
Paranasal sinus anatomical variations were found in 60% of patients in the study. The most common was Nasal Septum Deviation (28%), while the least common was Agger Nasi Cells (5%). CT scan is an excellent modality for surgeons to evaluate paranasal sinusitis before endoscopic sinus surgery.
