Risk Factors for Hypoparathyroidism Following Thyroidectomy

A Prospective Study to Assess Risk Factors for Hypoparathyroidism Following Thyroidectomy

The goal of this observational study is to identify the risk factors for post-thyroidectomy hypoparathyroidism in Estonia and to determine whether the magnesium level plays a significant role in the development of hypoparathyroidism. The main questions it aims to answer are:

• How common is post-thyroidectomy hypoparathyroidism in Estonia?
• What are the most significant risk factors for the development of post-thyroidectomy hypoparathyroidism in Estonia?
• Are magnesium levels a risk factor for the development of hypoparathyroidism? Participants will be asked to answer a questionnaire about risk factors. The study collects data on risk factors for hypoparathyroidism following thyroid surgery, including patient questionnaires and comorbidities, pre- and postoperative laboratory tests and surgery-related risk factors.

Inclusion Criteria:

• patients over the age of 18 undergoing surgery involving both lobes of the thyroid gland (thyroidectomy, "near-total" thyroidectomy, subtotal thyroidectomy, and "completed" thyroidectomy)
• patients who are capable of giving informed consent

Exclusion Criteria:

• patients undergoing unilateral thyroid lobectomy only
• patients with concomitant hyperparathyroidism undergoing simultaneous thyroidectomy and parathyroidectomy for a parathyroid adenoma
