Lobectomy
Pronunciation: loh-BEK-tuh-mee
Surgical removal of one lobe of the thyroid gland, typically performed for unilateral thyroid disease.
Full Definition
Thyroid lobectomy involves the surgical removal of one thyroid lobe, the isthmus, and sometimes the pyramidal lobe when present. This procedure is indicated for unilateral thyroid nodules with indeterminate or suspicious cytology, small thyroid cancers confined to one lobe, or symptomatic benign nodules. Lobectomy preserves thyroid function in most patients, avoiding the need for lifelong hormone replacement therapy required after total thyroidectomy. The procedure carries risks of recurrent laryngeal nerve injury and hypoparathyroidism, though these complications are less frequent than with total thyroidectomy.
Usage
Usage note: Distinguish from 'lobotomy' in medical transcription; specify 'thyroid' when context unclear.
