v.— THE SURGICAL TREATMENT OF CHRONIC 



ROARING. 



One day last week M. L — , of No. 12, Place Vendome, Paris, sent 

 us for examination a horse suffering from chronic roaring, asking 

 whether we would carry out on this .animal the operation performed 

 last year on a mare belonging to his neighbour, M. D — . He stated 

 that M. D — 's mare, which had suffered from intense roaring, render- 

 ing her useless before operation, was at that moment doing good 

 service, and that M. D — was very well pleased with the result. 

 I was not at the clinique on that day, but several of you will 

 remember the mare in question. The operation indicated was 

 arytasnoidectomy. 



I may shortly sketch the history of the animal thus cured. She 

 was an Anglo-Norman mare, which excited much attention at the 

 horse show of 1893, where she received the first prize for harness 

 horses. Bought towards the end of the show by M. D— , she worked 

 well until 1895. During the winter of 1895-6 she contracted pneu- 

 monia, and on return to work was found to have become a roarer. 

 She was unsuccessfully treated with iodide of potassium. The roaring 

 grew so marked that the animal, even at moderate paces, several times 

 fell in the shafts. M. D — took the advice of several veterinary 

 surgeons. A consultant told him that the disease was incurable, and 

 that he would have to dispose of the mare. M. D — replied that he 

 valued her greatly, and that he had heard speak of an operation which 

 without the use of a tracheotomy tube had several times rendered 

 roaring horses useful. He was informed that the operation did not 

 succeed once in a hundred times. 



Having been thus advised, M. D — came to me one morning at the 

 school, and asked whether I would consent to operate on his mare. 

 After having exactly informed him of the value of surgical treatment 

 for roaring, I proposed to first perform the small operation, and in 

 case of failure to perform the other — terms which he accepted. 



On the i8th January I performed partial cricoidectomy. Return- 

 ing to work on the 8th February the mare roared to the same extent 

 as before operation. Being sent back here on the 5th March I
