Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: When parathyroid tissue must be preserved during thyroid or parathyroid surgery, it is autotransplanted into a well vascularised, easily accessible muscle so that it can re-establish a blood supply and continue to secrete parathyroid hormone.
Step 2: The brachioradialis muscle of the forearm is the most common site for this autotransplantation, along with the presternal region.
Step 3: The brachioradialis is preferred because it is superficial, has a good blood supply, and any later recurrence of hyperparathyroidism can be treated by a simple limited excision under local anaesthesia.
Step 4: Other described sites include the sternocleidomastoid, subcutaneous tissue of the upper limb and abdominal fat, but among the options the answer is brachioradialis.
