The patient was stabilised with a temporary tracheostomy. Further investigations revealed the presence of anatomical malformations commonly encountered in dogs suffering from brachycephalic obstructive airway syndrome (BOAS). A CT scan of the patient's head also revealed the root of the right maxillary canine tooth (104) extending into the right nasal cavity. Rhinoscopic examination confirmed partial occlusion of the nasal airway by the presence of the tooth root. The right maxillary canine tooth was extracted, and postremoval rhinoscopy demonstrated an increase in the nasal cavity air-filled space on the right side. Subsequently, the patient underwent BOAS surgery but was unable to tolerate long-term removal of the tracheostomy tube postoperatively due to severe laryngeal collapse. A permanent tracheostomy was performed and the patient was discharged showing no signs of respiratory difficulties. © British Veterinary Association 2020. No commercial re-use.
