Laryngeal Paralysis
Laryngeal paralysis is a disorder where the nerves controlling the larynx fail, leading to breathing difficulties and potentially life-threatening airway obstruction.
Detailed Description
Laryngeal paralysis is caused by dysfunction of the recurrent laryngeal nerve, resulting in failure of the arytenoid cartilages to open during inspiration. It can be congenital or acquired, and may require surgical correction in severe cases.
Common Symptoms
- Noisy breathing (stridor)
- Exercise intolerance
- Voice change
- Cyanosis
- Collapse
Management Options
- Surgical correction (arytenoid lateralization)
- Weight management
- Environmental modification

Is this the same as geriatric laryngeal paralysis?
No, some breeds are predisposed to a congenital (early-onset) form.
