Objective

This study aims to evaluate the necessity of central and lateral cervical lymph node dissection (CLND and LLND) in the surgical management of thyroid nodules suspected to be malignant in pediatric patients.

Methods

A single-center retrospective analysis was conducted on patients under 18 years of age who underwent total thyroidectomy (TT) and/or CLND or LLND between January 2020 and June 2025. Preoperative decisions regarding LLND were made based on thyroglobulin washout (TGWO) and pathological findings indicating lateral neck lymph node metastases. CLND was performed intraoperatively in cases of confirmed central lymph node metastases or when lateral metastases were identified. Data on demographics, imaging, fine needle aspiration biopsy (FNAB), thyroglobulin washout, and surgical procedures were reviewed.

Results

The cohort included 67 patients with a median age of 14.1 years, of whom 67.1% (n=45) were female. The mean nodule size was 21 mm, and the malignancy rate was 64.1% (43/67), with a mean malignant nodule size of 18.5 mm. CLND was performed in 7.4% (5/67) of patients, while concurrent CLND and LLND were required in 25.3% (17/67). FNAB findings were statistically significant in predicting malignancy (p < 0.05), and TGWO positivity was strongly associated with metastatic lateral lymphadenopathy (p = 0.001). The classical variant of papillary thyroid carcinoma accounted for 76.7% (33/43) of malignancies. Additionally, prior neck radiotherapy and microcalcifications were significantly associated with malignancy (p < 0.05).

Conclusion

Metastasis to the central lymph node was observed in 7.4% of cases, while metastasis to both central and lateral neck regions occurred in 25.3%. Positive TGWO serves as a reliable preoperative predictor for lateral lymph node metastases. Surgeons managing pediatric thyroid surgery should be skilled in CLND to address the elevated risk of lymph node involvement in this population.
