Seizure and more Breathing Problems
Everted Larygeal Saccules

The saccules are essentially small bags of tissue that normally sit in a recession just in front of the vocal folds. When we breathe normally, we decrease the pressure in our lung and upper airway by expanding our chests. This action allows air to flow down our airway and into our lungs (just like the way we make liquid travel up a straw). Dogs with compromised airflow through the upper airway must work harder to fill their lungs with air. This decreases the pressure in the upper airway even more and literally pulls the saccules into the airway (just like the way a straw will collapse if you suck hard enough). When everted, the saccules sit just in front of the opening to the trachea and block the flow of air. The treatment for this problem is removal of the saccule tissue.
