Study Notes
Effects of Longstanding Thyroid Swelling
- Large thyroid swellings can exert pressure on the trachea, potentially leading to tracheal compression or narrowing.
- Airway obstruction may occur in severe cases, causing breathing difficulties and stridor.
Recurrent Laryngeal Nerve Pressure Symptoms
- Hoarseness or changes in voice may indicate pressure effects on the recurrent laryngeal nerve resulting from thyroid swelling.
- This nerve supplies the majority of the intrinsic muscles of the larynx, and its involvement suggests significant compression.
Consequences of Retrosternal Extension
- Retrosternal extension of thyroid swelling can lead to further complications, including mediastinal compression.
- This may result in symptoms like dyspnea (difficulty breathing) and can impact cardiovascular function if great vessels are compressed.
Assessment of Thyroid Hormone Status
- Patient history should include any symptoms of hyperthyroidism or hypothyroidism, such as weight changes, energy levels, and temperature sensitivity.
- Physical examination should include checking for signs of thyroid dysfunction, such as tremors or bradycardia, as well as examining the thyroid swelling itself.
MEN Type 2A Association
- Multiple Endocrine Neoplasia (MEN) type 2A is associated with medullary thyroid carcinoma, pheochromocytoma, and primary hyperparathyroidism.
- This genetic syndrome necessitates screening and monitoring for endocrine tumors due to the risk of malignancy.
