Protection of parathyroid function during thyroid surgery with a complete intermediate approach: a retrospective...

Area of Science:

• Endocrine Surgery
• Surgical Oncology
• Thyroid Surgery

Background:

• Iatrogenic parathyroid injury is a risk during thyroid surgery.
• The lateral approach is traditional, while the complete intermediate approach is gaining traction.
• Comparing these approaches for parathyroid function is crucial.

Purpose of the Study:

• To compare the effects of the complete intermediate approach versus the traditional lateral approach on postoperative parathyroid function.
• To evaluate the incidence of iatrogenic parathyroid injury between the two surgical methods.

Main Methods:

• A study of 270 papillary thyroid cancer patients undergoing total thyroidectomy.
• Patients were divided into complete intermediate (observation) and traditional lateral (control) groups.
• Parathyroid hormone and calcium levels were monitored for 6 months post-surgery.

Main Results:

• No significant preoperative differences in parathyroid hormone or calcium levels between groups.
• Postoperative parathyroid hormone and calcium levels were higher in the intermediate approach group.
• The intermediate approach group showed full recovery, while 4 control patients developed permanent hypoparathyroidism.

Conclusions:

• The complete intermediate approach offers superior protection of parathyroid function compared to the traditional lateral approach.
• This method significantly reduces the incidence of iatrogenic parathyroid injury after thyroidectomy.
