isthmusectomy

Full Definition

The surgical procedure involving removal of the thyroid isthmus, the narrow band of thyroid tissue that connects the right and left lobes. This limited procedure is occasionally performed for small tumors confined to the isthmus or as part of a broader thyroid resection. Medical editors should understand that isthmusectomy is a more conservative approach than lobectomy and typically preserves most thyroid function.

Usage

Usage note: Less common procedure; ensure distinction from more extensive thyroid resections.
