Total thyroid lobectomy, unilateral, is a surgical procedure that involves the removal of one lobe of the thyroid gland, which is a butterfly-shaped gland located in the neck. The thyroid is made up of two lobes, one on each side of the trachea, connected by a central isthmus. This procedure is typically indicated for patients with solitary nodules that are confined to a single lobe and have a high likelihood of being cancerous or are indeterminate based on biopsy results. It may also be performed for conditions such as follicular adenomas, solitary hot or cold nodules, or goiters that are localized to one lobe. The surgery begins with a transverse incision made in the skin over the thyroid, usually aligned with the natural creases of the neck to minimize scarring. Care is taken to protect vital structures such as the laryngeal nerve and the parathyroid glands during the procedure. The entire lobe on the affected side is excised, and if necessary, part or all of the isthmus may also be removed to ensure complete excision of any diseased tissue. The incision is then closed in layers to promote proper healing.
