Obstructive Upper Airway Disorders

Chapter 161 Obstructive Upper Airway Disorders

Obstructive upper airway diseases typically are insidious in onset and result in progressively worsening respiratory stridor and dyspnea. The dimensions of the upper airway play a fundamental role in the efficiency of breathing and progression of disease. In narrowed regions of the upper airway, air velocity is higher and pressure is lower than elsewhere (Bernoulli effect), which tends to narrow susceptible regions of the upper airway still more.


Congenital obstructive upper airway diseases are diagnosed so commonly in brachycephalic dogs that they are referred to collectively as the brachycephalic syndrome. Most other obstructive upper airway diseases are acquired and are diagnosed in middle-aged and older dogs. Obstructive upper airway diseases are diagnosed less frequently in cats.



Oropharyngeal Examination

A thorough oropharyngeal examination under light general anesthesia is diagnostic for most obstructive upper airway diseases.


Obtain radiographs of the pharyngeal, cervical, and thoracic regions.
