Abstract

Owing to recent interest shown in the aspiration and injection method of treating conditions of the middle ear, an instrument has been devised to simplify these procedures.

The aspiration of fluids from the middle ear cavity, such as in cases of otitis media with effusion,1 formerly required the help of an assistant during aspiration, since the operator steadied the syringe and needle with one hand while holding the electric otoscope with the other. The assistant withdrew the syringe plunger to aspirate the tympanic fluid. This act is often difficult to accomplish without movement of the needle in the tympanic membrane, which should be avoided.

The unassembled syringe holder for aspiration and injection of the tympanum is shown in part A of the figure.2

The syringe is securely fixed in the holder by a set-screw. A recoil spring is placed over the barrel of the syringe plunger, which is depressed prior
