Wide gagging prevents proper exposure of the larynx by
forcing the mandible down on the hyoid bone. The mouth should be
gently opened and a bite block (Fig. 16) inserted between the teeth on
the left side of the patient's mouth, to prevent closing of the jaws
on the delicate bronchoscope or esophagoscope.
[FIG. 16.--Bite block to be inserted between the teeth to prevent
closure of the jaws on the endoscopic tube. This is the
McKee-McCready modification of the Boyce thimble with the omission of
the etherizing tube, which is no longer needed. The block has been
improved by Dr. W. F. Moore of the Bronchoscopic Clinic.]
