Injury to the nerves in your vocal cords and larynx. You may have problems reaching high notes when you sing, hoarseness, weakness of your voice, coughing, swallowing problems, or problems speaking. These problems may be mild or severe.
Difficulty breathing. This is very rare. It almost always goes away several weeks or months after surgery.
A sharp rise in thyroid hormone levels (only around the time of surgery)
Injury to the parathyroid glands (small glands near the thyroid) or to their blood supply. This can cause temporary low level of calcium in your blood (hypocalcemia).
Too much thyroid hormone (thyroid storm). If you have an overactive thyroid gland, you will be treated with medicine.
Before the Procedure
You may need to have tests that show exactly where the abnormal thyroid growth is located. This will help the surgeon find the growth during surgery. You may have a CT scan, ultrasound, or other imaging tests.
Your doctor may also do a fine needle aspiration to find out if the growth is noncancerous or cancerous. Before surgery, your vocal cord function may be checked.
You may also need thyroid medicine or iodine treatments 1 to 2 weeks before your surgery.
Before surgery, an anesthesiologist will review your medical history and decide what type of anesthesia to use. The anesthesiologist is a doctor who will give you the medicines that will make you sleepy and keep you pain-free during surgery. The anesthesiologist will also monitor you during surgery.
Fill any prescriptions for pain medicine and calcium you will need after surgery.
Several days to a week before surgery, you may be asked to stop taking medicines that make it harder for your blood to clot. These include:
Ibuprofen (Advil, Motrin)
Naproxen (Aleve, Naprosyn)
You will probably be asked to stop eating or drinking at some point the night before or day of surgery. Your doctor or nurse will give you specific instructions.
Ask your doctor which medicines you should still take the day of surgery.
If you smoke, try to stop. Your recovery time will be shorter if you do not smoke. Ask your doctor or nurse for help.
Your doctor or nurse will tell you when to arrive at the hospital. Be sure to arrive on time.
After the Procedure
You will probably go home the day after surgery. In rare cases, patients spend up to 3 days in the hospital. You must be able to swallow liquids before you can go home.
Your doctor may check the calcium level in your blood after surgery. This is done more often when the whole thyroid gland is removed.
You may have some pain after surgery. Most patients are able to get up and walk on the day after surgery. It should take about 3 to 4 weeks for you to fully recover.
Follow any instructions for taking care of yourself after you go home.
Outcome of this surgery is usually excellent. Most people need to take thyroid hormone pills (thyroid hormone replacement) for the rest of their lives when the whole gland is removed.
