Perusal of the literature reveals but a single case of removal of a foreign body from the eustachian tube. Hastings1 removed a piece of gold bougie from the distal half of the eustachian tube during a radical mastoidectomy.
If a foreign body is lodged at a distance from the outer end of the tube it cannot be removed through the ear. The only available path is through the pharyngeal opening.
The entire length of the auditory tube is about 40 mm., and its smallest diameter at one point is less than 3 mm. To remove a foreign body an instrument must slide into the tube for at least 25 mm. if necessary (to the junction of the membranous and the bony canal) and have a diameter of less than 3 mm. It must also be surmounted with a grasping forceps.
The case here reported gave me the opportunity to use
