Clinical Information

  • Patients may need a parathyroidectomy if they have parathyroid masses that cause over or underproduction of the parathyroid hormone or PTH. 
  • There are multiple types of parathyroidectomy. They are traditional parathyroidectomy and scarless or transoral parathyroidectomy. 
  • If a patient undergoes surgery, some risks are changes in one’s voice, a sore throat, esophagus/trachea injury, bleeding/blood clot problems, and consistent low blood calcium levels. 
  • Before a parathyroidectomy, a patient will undergo blood tests, imaging tests, and laryngoscopy. 
  • For recovery, a patient may be asked to take calcium supplements and wait until their parathyroid glands work on their own. 

Synonyms Include:

  • Hyperparathyroidism, primary
  • Familiar hyperparathyroidism
  • Parathyroid hyperplasia
