What to Expect

Prior to Procedure

The surgical team may meet with you to talk about:

  • Anesthesia options
  • Any allergies you may have
  • Current medicines, herbs, and supplements that you take and whether you need to stop taking them before surgery
  • Medicines you may need to take before surgery, such as anti-thyroid medicines to suppress thyroid activity in people with hyperthyroidism
  • Fasting before surgery, such as avoiding food or drink after midnight the night before
  • Whether you need a ride to and from surgery


General anesthesia will be used. You will be asleep.

Description of Procedure

An incision will be made in the front of the neck. All or part of the thyroid gland will be removed. Lymph nodes may also be removed. The incision will be closed with stitches. A drainage tube may be inserted to allow fluids to leave the site.

This surgery may also be done using small incisions and specialized tools.

How Long Will It Take?

About 2 to 4 hours

Will It Hurt?

Pain and swelling are common in the first 1 to 2 weeks. Medicine and home care can help.

Average Hospital Stay

The usual length of stay is 1 day. You may need to stay longer if you have problems.

Post-procedure Care

At the Hospital

The staff may give you pain medicines.

During your stay, the hospital staff will take steps to lower your risk of infection, such as:

  • Washing their hands
  • Wearing gloves or masks
  • Keeping your incisions covered

There are also steps you can take to lower your risk of infection, such as:

  • Washing your hands often and reminding visitors and staff to do the same
  • Reminding staff to wear gloves or masks
  • Not letting others touch your incisions

At Home

It will take about 2 weeks to recover. Neck pain and a hoarse voice are common. Physical activity will be limited during this time. You will need to delay return to work.

Call Your Doctor

Call your doctor if you are not getting better or you have:

  • Signs of infection, such as fever and chills
  • Redness, swelling, excessive bleeding, or any discharge from the incision
  • Pain that you cannot control with medicine
  • Lasting nausea or vomiting
  • Felt very tired
  • Twitching or muscle spasms
  • Numbness or tingling around the hands, feet, or lips
  • Problems swallowing, talking, or breathing
