            Stridor



            Differential Diagnosis                  Key Features
            Airway stenosis/webbing (pharyngeal, laryngeal, or tracheal)  Uncommon cause of stridor; usually follows insult or injury to the airway; recognized on laryngoscopy/
                                                    tracheoscopy
            Brachycephalic syndrome                 More often characterized by stertor than stridor; breed-related congenital and acquired anatomic
                                                    defects (not all defects present in affected dog—stenotic nares, elongated soft palate, everted laryngeal
                                                    saccules, and hypoplastic trachea); chronic signs
            Coagulopathy                            Acute onset of stridor due to hematoma formation; more likely related to secondary (e.g., anticoagulant
                                                    rodenticide intoxication) than primary hemostatic defect; unless other evidence of bleeding identified,
                                                    may not be recognized before sedated airway exam
            Epiglottic retroversion                 Epiglottis episodically retroflexed into the rima glottidis; easily missed on pharyngeal/laryngeal exam due
                                                    to episodic nature and self-correction when tongue is extended forward; seemingly uncommon
            Extraluminal laryngeal compression      Compression from mass, lymphadenomegaly, abscess, or granuloma; can have either acute or insidious
                                                    onset of clinical signs, depending on cause
            Extraluminal tracheal compression       Compression from mass, lymphadenomegaly, abscess, or granuloma; can develop acute or insidious
                                                    onset of clinical signs; careful palpation of the neck may reveal mass
            Foreign body                            Material lodged in pharynx, larynx, or upper portion of trachea; depending on density, may be identified
                                                    on cervical radiographs; laryngoscopy/tracheoscopy diagnostic and therapeutic
            Laryngeal collapse                      Breed related in Norwich terriers; can occur as complication of brachycephalic airway syndrome;
                                                    confirmed via imaging studies ± laryngoscopy
            Laryngeal edema                         Acute onset typical; can follow envenomation/bite or exposure to caustic chemical (e.g., liquid potpourri);
                                                    confirmed via laryngoscopy; depending on cause, glucocorticoids may be helpful but temporary
                                                    tracheostomy occasionally required
                                                                                                            Continued
