What is the key space for recognizing the location of masses in the neck?
Parapharyngeal space is the key space!
Why is the recurrent laryngeal nerve a problem in vocal cord paralysis?
Because the laryngeal nerve dives into the chest and then back up to the neck. The length of t makes it more likely it could be damaged

Graves’ Opthalmopathy?
an autoimmune inflammatory disorder affecting the orbit around the eye, characterized by upper eyelid retraction, swelling (edema), redness (erythema), conjunctivitis, and bulging eyes (proptosis)
The autoantibodies target the fibroblasts in the eye muscles, those fibroblasts can differentiate into fat cells. Fat cells and muscles expand and become inflamed. Veins become compressed, and are unable to drain fluid, causing edema
