PHARYNGEAIv AND LARYNGEAIv POIvYPI. 



Pediculated tumors. Dyspnoea through change of position, operation by 

 ecraseur, snare or cricoid incision. 



Tumors of varied structure developing in or beneath the mu- 

 cosa 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 dyspnoea. 

 Pediculated tumors in the posterior nares lead to the same acci- 

 dent. 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, neces- 

 sitating prompt tracheotomy. A time was set for the removal of 

 the pol3rpus, but the tracheotomy tube having been accidentally 

 displaced during the preceding night the patient died of suffoca- 

 tion. 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.
