Cervical spondylosis and ankylosing hyperostosis of the cervical vertebrae are common findings. Although these hypertrophic changes can be completely asymptomatic, it is known that dysphagia may occur occasionally in the presence of massive cervical hyperostosis. Laryngotracheal symptoms due to cervical hyperostosis are less frequent and may be managed initially as tumors of the esophagus, trachea, or thyroid gland. The management of two severe cases of dyspnea due to cervical ankylosing hyperostosis are discussed.
- ankylosing hyperostosis
- diffuse idiopathic skeletal hyperostosis
