What is a potential complication of a subtotal thyroidectomy?

A subtotal thyroidectomy involves the surgical removal of a portion of the thyroid gland, and while it can effectively treat conditions like hyperthyroidism and certain thyroid nodules, it carries the risk of potential complications. One significant risk is bleeding from the surgical site. This can occur during or after the procedure due to the rich vascular supply of the thyroid gland. If bleeding occurs, it can lead to hematoma formation, which may compress surrounding structures in the neck, potentially compromising the airway.

Monitoring for signs of bleeding is crucial after the surgery. Signs include swelling at the surgical site, difficulty breathing, and changes in voice due to potential pressure on the laryngeal nerve or airway. Immediate medical intervention may be necessary if significant bleeding occurs, making this complication one of the critical considerations in the postoperative care of a patient who has undergone a subtotal thyroidectomy.

While the other options may represent possible issues related to hormonal balance and respiratory function, the specific risk of bleeding directly pertains to the surgical context and immediate postoperative care.
