Singing Rainbows


As vocalists know, the nasal cavity, oral cavity, and pharynx play instrumental roles in the rich, resonating tones so essential to their art. Wouldn’t they be amazed that their instruments for producing euphony and coloratura can assume undulating, visual colors when rendered with medical imaging visualization technology? Such singing rainbows are evident in this three-dimensional computed tomographic image from virtual endoscopy, which reveals the left lateral wall of the nasopharynx, as seen from the right choana; the bulging torus tubarius and Rosenm├╝ller fossa (left), visible behind the semilunar-shaped recess for the pharyngeal opening of the eustachian tube; the left inferior nasal concha (center), seen projecting behind the posterior edge of the nasal septum; and the soft palate at the bottom.
