completion thyroidectomy
Surgical removal of the remaining thyroid lobe after prior hemithyroidectomy. Often performed when cancer is discovered on final pathology.
Full Definition
Completion thyroidectomy is a surgical procedure involving removal of the remaining thyroid lobe following a previous hemithyroidectomy or lobectomy. This procedure is most commonly indicated when final pathology reveals thyroid cancer with features requiring total thyroidectomy, such as multifocal disease, extrathyroidal extension, or high-risk histology. The surgery is technically more challenging than primary total thyroidectomy due to scar tissue formation and altered anatomy from the initial procedure. Careful identification of the recurrent laryngeal nerve and parathyroid glands is crucial, as the risk of complications may be higher than in primary surgery.
