A 2.4-kg, six-year-old, sterilised, male Pomeranian presented with dyspnoea that had begun two years prior and slowly progressed. Pharyngoscopy identified a redundant laryngopharyngeal mucosal fold that was being aspirated cranially into the laryngeal opening causing upper airway obstruction. A diode laser was used to resect the fold. Postoperative laryngeal oedema necessitated the use of a tracheostomy tube for just over two days. Otherwise, the dog made an uneventful recovery. To the authors’ knowledge, this is the first report of a redundant laryngopharyngeal mucosal fold resulting in upper airway obstruction in a dog.

A 9-year-old intact male Bluetick Coonhound presented for progressive subcutaneous emphysema of 5 days' duration due to a suspected tracheal tear. Cervical computed tomography (CT) and thoracic CT were performed after failure to identify the tracheal tear with tracheoscopy. A longitudinal tracheal tear was identified starting 4.3 cm cranial to the tracheal bifurcation and extending caudally over a distance of 3.6 cm. Severe pneumomediastinum, subcutaneous emphysema, and retroperitoneal gas were also present. A follow-up CT 7 days postoperatively confirmed the successful repair of the tear with partial resolution of the presurgical secondary pathology and the patient recovered uneventfully.
