Understanding the Risks of Total Thyroidectomy
Thyroid surgery is a standard procedure used to treat several thyroid conditions, such as cancer, noncancerous enlargement (goitre), or overactive thyroid (hyperthyroidism). Total thyroidectomy involves removing the entire thyroid gland, while subtotal thyroidectomy removes part of the gland. Although these surgeries can be life-saving, they come with their own set of potential risks and considerations.
Total Thyroidectomy Procedure Steps
A total thyroidectomy is a major surgical procedure. Before undergoing surgery, it's crucial to understand the steps involved. Initially, the patient is placed under general anaesthesia. The surgeon then makes an incision in the neck to access the thyroid gland, carefully avoiding the surrounding nerves and blood vessels. The entire gland is removed, and the incision is closed with sutures. The patient usually stays in the hospital for observation before being discharged.
Subtotal Thyroidectomy Procedure Steps
The subtotal thyroidectomy follows similar initial steps as the total thyroidectomy. However, in this procedure, the surgeon removes only a portion of the thyroid gland, leaving behind some thyroid tissue. This approach is sometimes chosen to maintain some thyroid function and minimize the risks associated with removing the entire gland.
Total Thyroidectomy Complications
Like any surgical procedure, total thyroidectomy comes with possible complications. These can include:
- Hypoparathyroidism: This condition occurs when the parathyroid glands, which are adjacent to the thyroid gland, are damaged during surgery, leading to low levels of calcium in the blood.
- Vocal cord paralysis: The nerves controlling the vocal cords may be affected, leading to hoarseness, voice changes, or difficulty breathing.
- Infection and bleeding: As with any surgery, there is a risk of infection at the incision site and bleeding.
- Thyroglobulin levels: After a total thyroidectomy, thyroglobulin (a protein produced by the thyroid gland) levels should be undetectable or very low. Elevated levels might indicate thyroid tissue remnants or cancer recurrence.
Foods to Avoid After Total Thyroidectomy
After a thyroidectomy, the body's metabolism changes. Certain foods, especially those rich in iodine, may need to be limited. Foods to avoid or reduce include:
- Iodized salt
- Seafood and seaweed
- Dairy products
- Egg yolks
- Some bread and baked goods
Monitoring and Managing Risks
Post-surgery, it's crucial to follow up with your healthcare provider to monitor thyroglobulin levels and other indicators of thyroid function. Regular check-ups will help manage any complications and adjust medications as necessary.
Patients who undergo a total thyroidectomy will require lifelong thyroid hormone replacement therapy. It's essential to work with an endocrinologist to find the correct dosage and maintain a balanced thyroid hormone level in the body.
Conclusion
Both total and subtotal thyroidectomy procedures are effective treatments for various thyroid conditions. However, understanding the risks and the steps you can take to manage them is critical to a successful outcome. If you're considering thyroid surgery, discuss all aspects with your healthcare provider to make an informed decision about your treatment plan.

Book an AppointmentFrequently Asked Questions
Total thyroidectomy is a surgical procedure involving the complete removal of the thyroid gland from the neck. It's commonly performed to treat thyroid cancer, large goiters, or severe cases of hyperthyroidism.
In a total thyroidectomy, the parathyroid glands, which regulate calcium levels, are at risk but not intentionally removed. However, accidental damage or removal can occur, leading to potential complications such as hypocalcemia.
Thyroid cancer recurrence is possible after a total thyroidectomy, although less likely if the surgery effectively removes all cancerous tissue. Regular monitoring and follow-up care are crucial to detect and manage any recurrence early.
No, total thyroidectomy typically does not include removal of the parathyroid glands. However, these glands, responsible for regulating calcium levels, are at risk of damage during the procedure.
Subtotal thyroidectomy involves the removal of a portion of the thyroid gland, leaving some thyroid tissue intact. This procedure is often chosen to address conditions like noncancerous nodules or hyperthyroidism while preserving thyroid function.
Subtotal thyroidectomy may be preferred over total thyroidectomy when the goal is to preserve some thyroid function, especially in cases of noncancerous thyroid conditions. It also reduces the risk of complications associated with complete removal of the thyroid gland.
