The normal carinal angle at the tracheal bifurcation is around?
40-50 degrees
50-60 degrees
60-75 degrees
75-90 degrees
Ans CCarinal angle is influenced by indentation from adjacent structures/lesions on the tracheal bifurcation. Normally it is 60 to 75 degrees. Any mass at carina like duplication cysts or left atrial enlargement results in widening of the angle.
