Hemithyroidectomy, or unilateral thyroid lobectomy, refers to removal of half the thyroid gland. The procedure is typically performed for suspicious thyroid nodules or small differentiated thyroid cancers based on biopsy via fine needle aspiration (FNA) and occasionally for symptomatic benign thyroid nodules.

At most institutions the operation can be completed safely in an outpatient fashion with patient discharge from the hospital the same day. It is typically performed via a transcervical collar incision, but endoscopic, transoral routes and remote access approach with robotic instrumentation have been described. The procedure involves mobilization of the thyroid lobe, ligation of thyroid vessels, preservation of parathyroids, protection of the recurrent laryngeal nerve, and dissection away from the trachea. In this patient, a thyroid nodule was detected and found to have indeterminate features on biopsy via FNA. A hemithyroidectomy was then performed for diagnostic purposes.
