Example sentence:

The choanae are the posterior apertures of the nose. Each choana is bounded medially by the vomer, inferiorly by the horizontal plate of the palatine bone, laterally by the medial pterygoid plate, and superiorly by the body of the sphenoid bone

The effect of nasopharyngeal pressures on a pliant Eustachian tube (Toynbee phenomenon) due to obstruction of the posterior nasal choanae by the adenoid mass was suggested as a possible cause of functional Eustachian tube obstruction.
