BACKGROUND: The most common location for supernumerary or ectopic parathyroid glands is the thymus.
METHODS: A review of patients who underwent parathyroidectomy for hyperparathyroidism from 1990 to 2010 was completed to determine indications for thymectomy, the yield of parathyroid tissue, and outcome of therapy.
RESULTS: Seventy of 379 patients with hyperparathyroidism underwent parathyroidectomy and transcervical thymectomy. Intrathymic parathyroid tissue was present in 23 (33%) patients, including supernumerary glands in 8 patients (11%). Indications for thymectomy were renal hyperparathyroidism in 35 patients (50%) and primary hyperparathyroidism with a missing inferior gland in 20 patients (29%), an ectopic adenoma in 9 patients (13%), hyperplasia in 5 patients (7%), and carcinoma in 1 patient (1%). Cure rates were similar (96% and 98%; P = not significant) and only transient hypocalcemia was higher (51% vs 24%, P < .05) after parathyroidectomy with thymectomy versus parathyroidectomy alone.
CONCLUSIONS: Transcervical thymectomy results in a high yield of parathyroid tissue and is essential for cure of selected patients with hyperparathyroidism.
