Total internal reflection for positioning Jones tube.
Visualization of the Jones tube in the internal nose often poses difficulty for the surgeon and threatens the success of the operation. Postoperatively, localizing the end of the tube in the nose in order to confirm its placement or to analyze the cause of failure may also be technically challenging. A method of visualizing the tube in the nose under both surgical and postsurgical conditions is herein described.
