Determination of Normal Frontal Sinuses Dimensions Using Computed Tomography

Abstract

The purpose of this study is to determine the anatomical dimensions of the frontal sinus using computerized tomography (CT). 94 Sudanese subjects 57 males and 37 females were investigated for CT head and sinuses; determinations of the frontal sinus in coronal and axial sections dimensions were evaluated. According to age, group and gender. The study was carried out in Khartoum state, from 20 September to 20 November 2015 in radiology departments of, Alamal National Hospital, Almudres Medical Center and Sudan Diagnostic Center. The measurements also taken from 20 year and development of the frontal sinus is complete in 20 years. The study showed the mean of right width =21.56 mm and for the left width =22.71mm Measure of right height =14.81, for left height 15.40 mm, the right antroposterior =7.73mm, and the left anteroposterior =8.06 mm. showed the left side of frontal sinus is greater than the right one and deals with other studies. The mean of right width =19.50mm and for the left width =21.77 mm Measure of right height =12, for left height 13.48 mm, the right antroposterior =6.73 mm, and the left anteroposterior =7.79 mm. for male distribution the mean of right width= 20.76 mm less than the left width =23.43 mm. Mean of right height= 13.87 mm less than the left height=15.48 mm. The anteropostrior measure of right side mean =7.98 mm less than left=8.98 mm and also demonstrates the males have grater frontal sinus than female. The study provides essential anatomical information for Sudanese subjects.
