Left-sided partial arytenoidectomy was performed in eight horses to evaluate healing. Four horses underwent conventional partial arytenoidectomy with suture apposition of the mucosa. In four horses, most of the arytenoid cartilage, including overlying mucosa, vocal fold, and laryngeal saccule, were excised en bloc without mucosal closure. The horses were… (More)
By use of endoscopy, 75 horses with respiratory noise and/or exercise intolerance were determined to have structural arytenoid cartilage abnormalities (60 primary, 11 after previous laryngeal surgery), or failed left laryngoplasty (4 horses) for laryngeal hemiplegia in which the arytenoid cartilage still appeared normal. Eighty-eight percent of the horses… (More)
Bilateral arytenoidectomy had been performed as treatment for bilateral arytenoid chondritis in 2 horses. After surgery, dorsal mucosal defects were associated with subsequent development of dorsal glottic stenosis in the 2 horses. When performing bilateral arytenoidectomy in the horse, care must be taken to eliminate dorsal mucosal defects that cross the… (More)
Endoscopic examinations of the upper respiratory tract were done on 92 of 314 Standardbred horses that raced one or more times at 4 consecutive, weekly race meetings. Although participation was voluntary, the characteristics of the population of horses examined were not statistically different from those of all horses that raced. No horse showed epistaxis,… (More)
A nine-year-old gelding was presented to the Auburn University Large Animal Clinic with discharge of saliva and food material from both nostrils. A diagnosis of esophageal diverticulum was made; treatment is described.
Laryngeal hemiplegia was induced in 4 ponies via a left recurrent laryngeal neurectomy. Reinnervation of the denervated left cricoarytenoideus dorsalis muscle was then attempted using a muscle pedicle graft from the right cricoarytenoideus dorsalis muscle. In 3 ponies there was no return of abductor function and failure of graft survival. In the fourth pony… (More)
Cecal torsion in horses is relatively rare. This clinical report describes cecocolic fold hypoplasia, producing increased cecal mobility, as a predisposing cause of cecal torsion in a horse.
Of 147 horses treated for umbilical hernias over a 13.5-year period, 13 horses (8.8%) developed complications in association with umbilical defects. Six horses had intestinal incarceration; the incarceration was reduced manually in 3 horses before admission, resolved without treatment in 2 others, and was surgically reduced in one. Herniorrhaphy was… (More)
Review of medical records of 78 horses admitted to the George D. Widener Hospital for Large Animals with dorsal displacement of the soft palate revealed 94% of these horses to have evidence of an intermittent abnormal "gurgling" respiratory noise at the time of exercise. Sternothyrohyoideus myectomy was used as a primary treatment for 17 of these horses,… (More)
