Plain-English summary
In this study, researchers looked at four dogs showing signs of laryngeal paralysis, which is a condition that affects their ability to breathe properly, and compared them to three healthy dogs. They used a method called transnasal laryngoscopy, where a small camera was inserted through the dog's nose after giving them a sedative and numbing their nose. This allowed the vets to see how the dog's larynx was functioning while they were breathing normally. They confirmed that the four affected dogs had laryngeal paralysis, and this was also verified with a more traditional examination in three of those dogs. Overall, transnasal laryngoscopy proved to be an effective way to diagnose laryngeal paralysis without needing to put the dogs under general anesthesia.
Abstract
Four dogs with clinical signs of laryngeal paralysis and three normal dogs were evaluated with transnasal laryngoscopy. Six of these dogs subsequently underwent standard laryngoscopy. For transnasal laryngoscopy, a video endoscope was passed through the left nasal passage after intramuscular sedation and topical anesthesia. The laryngeal opening was observed during spontaneous ventilation. Laryngeal paralysis was diagnosed in four dogs and was confirmed with traditional laryngoscopy in three dogs. Normal motion of the arytenoid cartilages was present in the other three dogs; however, two required mechanical stimulation of the laryngeal mucosa for full evaluation. Transnasal laryngoscopy provided a means for diagnosing laryngeal paralysis in dogs without general anesthesia.
