Pediculated tumors. Dyspnœa through change of position, operation by
ecraseur, snare, or cricoid incision.
Tumors of varied structure developing in or beneath the mucosa of
pharynx or larynx often become slowly detached until they hang by a
loose pedicle, and having much latitude of movement they may at times
slip between the arytenoid cartilages or even into the glottis producing
the most urgent or even fatal dyspnœa. Pediculated tumors in the
posterior nares lead to the same accident. In one case of multiple small
tumors on the pharyngeal mucosa of the horse, the largest and loosest,
attached to the front of the epiglottis, was occasionally displaced into
the larynx threatening instant asphyxia. One such attack supervened on
the opening of a suppurating guttural pouch by the writer, necessitating
prompt tracheotomy. A time was set for the removal of the polypus, but
the tracheotomy tube having been accidentally displaced during the
preceding night the patient died of suffocation. Dick mentions a polypus
growing from the interior of the larynx and causing loud _roaring_. Such
tumors may be removed by operating with the _ecraseur_ through the
mouth, or by a snare passed through a long narrow tube and used to seize
and twist through the pedicle. If the polypus grows from the laryngeal
walls, it may be best reached by incision through the cricoid cartilage
and crico-thyroid membrane as in the operation for _roaring_.
