Introduction
Surgery in the central compartment after previous thyroidectomy involves an increased risk of injury to critical organs, including the parathyroids and recurrent laryngeal nerve. Contrastingly, primary central neck dissection involves a relatively low operative risk.
Objective
This study aimed to compare the outcomes of central neck dissection in primary versus revision settings with respect to the lymph node yield and complication rates.
Methods
This single-center prospective study included patients who underwent primary or revision neck dissection surgery for histologically confirmed thyroid malignancy between January 2018 and January 2022.
Results
We included 30 patients who underwent total thyroidectomy with primary central neck dissection and 29 patients who underwent central neck dissection following remote thyroidectomy with or without previous central dissection. There was no significant between-group difference in postoperative complications, including permanent hypocalcemia and recurrent laryngeal nerve injury. However, both groups showed a significant postoperative decrease in calcium levels even though calcium and parathyroid hormone levels were within reference range.
Conclusion
Although many surgeons fear revision central neck dissection, it appears to have similar therapeutic outcomes and complication rates as primary neck dissection for papillary thyroid cancer. Specifically, there were no between-group differences in the lymph node yield, hypoparathyroidism, or recurrent laryngeal nerve paralysis. Patients with normocalcemia showed a significant postoperative reduction in calcium levels, suggesting subclinical parathyroid insufficiency.
