Dorsal glottic stenosis after bilateral arytenoidectomy in two horses.

This research paper details the development of dorsal glottic stenosis in two horses following bilateral arytenoidectomies, a surgery performed as a treatment for bilateral arytenoid chondritis. The study emphasizes the importance of eliminating dorsal mucosal defects that cross the midline to prevent the potential complication of glottic stenosis.

Objective of the Research and Methodology Used

• The study was conducted to unravel the link between bilateral arytenoidectomy, a type of surgery conducted on horses to treat bilateral arytenoid chondritis, and development of dorsal glottic stenosis, a complication that had arisen in two horses.
• The researchers focused on the dorsal mucosal defects that had been an aftermath of the arytenoidectomy and studied their correlation with the emerging condition of glottic stenosis.

Findings

• The researchers discovered that the two horses developed dorsal glottic stenosis post-surgery because of the presence of dorsal mucosal defects that were crossing the midline.
• The conclusion was that if these defects are not closed or eliminated, they can lead to the development of glottic stenosis, potentially causing an obstruction in the horse’s respiratory tract.

Significance and Recommendations

• This research is significant in presenting vital insights into complications that can arise following the surgery of bilateral arytenoidectomy in horses. It pinpoints a certain aspect of the surgical aftermath that could lead to additional complications.
• As a result of their findings, the researchers recommend that during bilateral arytenoidectomy, surgeons take precautionary measures to either eliminate or close any dorsal mucosal defects that cross the midline. Doing so should help in avoiding the development of dorsal glottic stenosis in horses.
