Introduction: The study of bronchial tree is done by both invasive and non-invasive techniques like cadaveric dissection, bronchograms, virtual bronchoscopy, Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) scan.
Materials and Methods: The subcarinal angle of trachea was measured on chest CT scans of 110 normal adult individuals in the age group of 10-70 years (69 males and 41 females) attending the department of Radio-diagnosis at Government Medical College, Aurangabad.
Result: The mean value for subcarinal angle was 80.01 ± 12.53 in males, 79.75 ± 9.990 in females and  79.92 ± 11.600  in total study population.
The difference between means of subcarinal angle in male and female population was not significant statistically (‘p’ value=0.902).  In the age group 11-20 years, the differences between the mean values of subcarinal angle were affected by sex to a very small extent as compared to other age groups.
Discussion: It was observed that widening of the tracheal bifurcation angle had long been accepted as a sign of left atrial enlargement, but conflicting data are present about its reliability.
Conclusion: The mean value of subcarinal angle is independent of age and gender. This study is useful for clinicians to know the changes in left atrium and while doing  endotracheal intubation and bronchoscopy.
Key words: Trachea, Subcarinal angle, CT Scan.
