METHODS The cross-sectional descriptive study was conducted at the Radiology Department of Jinnah Postgraduate Medical Centre, Karachi, from November 2018 to April 2019, and comprised adult females who were divided into four equal ethnic groups. Frontal sinus X-ray radiography was done using the Water's view. Width, height and area of the right and left frontal sinuses were measured. The radiographs were saved in photograph format and measurements were done using RadiAnt DICOM software. Measurements of height, width and area were noted. Data was analysed using SPSS 23. RESULTS There were 108 females; 27(25%) in each of the four groups. The overall mean age was 35.14±8.68 years. Variability in terms of width, height and area were noted in both right and left frontal air sinuses (p<0.001).
