Background/purpose: Thyroidectomy is the primary therapy for thyroid cancer and an established treatment of hyperthyroidism. Because of the relative rarity of these conditions in childhood, few single-institution series exist in the pediatric literature. Here we analyze our institution's experience to assess patient demographics, operative risks, and the role of preoperative testing.
Methods: This is a retrospective chart review of 175 consecutive patients not older than 18 years who underwent thyroid surgery at Children's Hospital Boston from 1970 to 2004.
Results: The most common indication for thyroidectomy was thyroid nodules (83%), followed by hyperthyroidism (7%) and goiter (7%). For children referred for nodules, we observed a peak incidence in adolescence and a female to male ratio of 3.7:1. Cancer was found in 36%, with papillary thyroid cancer the most common subtype (85%). Operative complications were rare, with permanent hypocalcemia in 2 (4.7%) of 43 patients who underwent bilateral resection for thyroid nodules (no cases of permanent hypocalcemia in other procedures). Permanent unilateral vocal cord paralysis was documented in 2 children after the resection of malignant nodules.
Conclusions: Pediatric thyroidectomy can be performed with low operative risk. Because permanent hypocalcemia remains an obligate risk of bilateral thyroidectomy, we recommend the routine use of preoperative fine-needle aspiration to guide the extent of initial surgical resection, reserving near-total thyroidectomy for those cases where cytology is positive for malignancy.
