The object of the new instruments was to combine in one instrument what ordinarily is carried out by two. There are two models. One combines in the same tongue depressor a flange on each side for retracting the pillar. The other is a combination of two tongue depressors, one serving as a handle while the other is used as a depressor. This is arranged with a flange on one side and can be used for the right or the left tonsil.
