Treatment of laryngeal paralysis in dogs with silicone endoprostheses

Laryngeal paralysis in dogs is an emergency condition that worsens upper respiratory distress and causes life-threatening disease. So far, surgical arytenoid lateralisation is a typical treatment method. In two recent articles [1, 2], the placement of a silicone laryngeal stent has been shown to be very effective in the treatment of laryngeal paralysis.

The procedure is simple and inexpensive. In humans, silicone laryngeal stents are very effective in treating upper airway obstruction for short and long periods. Théron and Lahuerta-Smith report that dogs survived up to 13 months after installation of silicone laryngeal stents [1].

The authors expect longer survival and more clinical applications in the future. Considering that laryngeal paralysis is common in small animals [3], silicone laryngeal stenting may be a valuable approach for small animal surgeons in the treatment of laryngeal paralysis in dogs and cats.

Full details of this study are available in this issue of the Journal.
