Plain-English summary
Four dogs showing signs of laryngeal paralysis, such as difficulty breathing or noisy breathing, were examined using a new method called transnasal laryngoscopy, which allows vets to look at the larynx without needing general anesthesia. This method involved using a small camera inserted through the nose while the dogs were lightly sedated. Laryngeal paralysis was confirmed in three of the dogs with a follow-up traditional laryngoscopy. This approach is helpful for diagnosing breathing issues in dogs while minimizing the risks associated with 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.
