Mr. Oamgee has described a very formidable operation, under 

 B more ibrmidable name, viz., Hyo-vertebrotomy, for the pur- 

 pose of giving exit to pus in the guttural pouches. The 

 operation is quite unnecessary ; and [ am surprised that any one 

 knowing the anatomy of the parts so well as Mr. Gamgee, 

 should not have thought of operating underneath the parotid 

 gland. If both pouches arc filled with pus, the operation is to 

 be performed on both sides. 



rilARYNGEAL rOLYTI. 



'^Tumours, with long pddicles. are sometimes found in the fauces, 

 v.'hich by failing into the phar^-nx or larynx constitute pharyn- 

 geal or laryngeal polypi. 



The symptoms which they produce are those of choking, dilTi- 

 culty of breathing, incessant efforts to coirgh, and a flow of saliva 

 from the mouth. Tn some instances ^' intermittent roaring" is 

 the only synaptom of their presence. 



They are detected by e.\'amiuaLion of the fauces, and are to bo 

 removed by the "ecrasear." torsion, and when they present a 

 broad base, they are to be destroyed, " slouglicd out" by esclia- 

 rotics.

 tliiclc coarse paper, bccouiing lodged in the pharynx or a'sophagus. 



Eggsj Ported into the piiax^nx liav'e often proved a source of 

 obstruction.
