Diffuse idiopathic skeletal hyperostosis (DISH): an unusual cause of airway obstruction

Characteristically, ossification of the anterior longitudinal ligament is seen, resulting in the formation of intervertebral osteophytes. 2 Although asymptomatic in most cases, patients may have symptoms such as dysphagia and dysphonia, and very rarely airway obstruction. 3 Acute airway obstruction is rare in this condition, but securing a safe airway follows the same protocol and assessment as for the other causes.
