Cartilage Anatomy & Pathology
The key anatomy involved in the swallowing pathway are connected to a cartilaginous superstructure, especially in the larynx. The foundation is the cricoid cartilage, which undergirds the thyroid cartilage, arytenoids, and other critical anatomy. These structures provides protection and support while retaining the ability to move in a highly dynamic manner to facilitate swallowing. The need to balance these various functions creates a delicate equilibrium which can be disrupted at any point in the cartilaginous superstructure.
Eagle Syndrome
Eagle Syndrome is a constellation of clinical findings that are present in the setting of an elongated styloid process. The styloid process is a key anatomical structure of the pharynx, and as such is central to swallowing and mastication. Classic clinical findings include cervicofacial pain, dysphagia, and foreign body sensation. However, vascular and neurologic variants exist as well, which can lead to significant morbidity including stroke or carotid dissection.
