Prevention
This technique seems to offer improved exposure and reliable control of the neuro-vascular structures in the anterior mediastinum when resecting a huge substernal goiter that may prevent nerve injury. [ncbi.nlm.nih.gov]
Downward migration of the thyroid into the mediastinum is facilitated by negative intra-thoracic pressure, gravity, traction forces during swallowing and the presence of anatomical barriers preventing the enlargement in other directions (thyroid cartilage [slideshare.net]
Treatment consists of iodine replacement; although this will not cure the condition, it can stop it from enlarging, and iodine administered in advance will prevent development of goiter. exophthalmic goiter any type accompanied by exophthalmos. fibrous [medical-dictionary.thefreedictionary.com]
