Total thyroidectomy: reduction in postoperative hypoparathyroidism

Area of Science:

• Endocrinology
• Surgical Oncology
• Thyroid Surgery

Background:

• Total thyroidectomy carries a significant risk of postoperative hypoparathyroidism due to potential damage to parathyroid glands or their vascular supply.
• Surgeons with expertise in both thyroid and parathyroid procedures may achieve better outcomes in thyroidectomy.
• High rates of permanent hypoparathyroidism negatively impact patient quality of life and increase long-term morbidity.

Purpose of the Study:

• To investigate the impact of centralizing total thyroidectomy for Graves' disease to experienced surgeons on postoperative hypoparathyroidism rates.
• To evaluate the effectiveness of restricting thyroidectomy procedures to surgeons skilled in both thyroid and parathyroid surgery.

Main Methods:

• A retrospective cohort study was conducted at a single institution.
• Thyroidectomies for Graves' disease were initially performed by seven surgeons (2012-2016).
• From 2017, these procedures were restricted to two surgeons with concurrent parathyroid surgery experience.

Main Results:

• The overall rate of permanent hypoparathyroidism after total thyroidectomy decreased from 28% (2012-2014) to 6% (2020-2021).
• For Graves' disease patients, permanent hypoparathyroidism rates dropped from 36% (2015-2016) to 2% (2020-2021).
• In thyroid cancer patients, rates decreased from 30% (2012-2014) to 10% (2020-2021).

Conclusions:

• Centralizing total thyroidectomy to surgeons with extensive parathyroid surgery experience markedly reduces postoperative hypoparathyroidism.
• This strategy improves patient outcomes and quality of life by minimizing a serious surgical complication.
• Recommendations include centralizing complex thyroid operations to high-volume centers with specialized surgical expertise.
