Hemithyroidectomy: Partial Thyroid Removal Indications and Benefits

A hemithyroidectomy (removal of one thyroid lobe) is performed for benign nodular goiter, a solitary nodule requiring biopsy, or thyroid cancer confined to one lobe. Total thyroidectomy is reserved for advanced cancer, recurrent goiters, or bilateral disease. Preserving thyroid tissue when possible maintains natural hormone production, reducing the need for lifelong replacement therapy.
