Glossectomy: what the operation involves | CION Cancer Clinics
A glossectomy removes part, or occasionally all, of the tongue to take out a cancer along with a border of healthy tissue. You are asleep throughout. Many patients also have lymph nodes removed from the neck in the same operation, and a larger gap is rebuilt with tissue from the forearm or thigh. This page explains each step, what is often added, and what your surgeon cannot promise. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What actually happens in a glossectomy?
A glossectomy is an operation to remove part, or occasionally all, of the tongue because a cancer is growing in it. You are asleep throughout, the surgeon takes out the cancer with a rim of healthy tongue around it, and a larger gap is rebuilt with tissue from elsewhere in your body.
Why more than the lump is removed
Tongue cancer spreads along the muscle fibres, so the cancer you can see is often smaller than the cancer that is there. The surgeon removes a margin (a border of normal-looking tissue) so that the edge of what is taken out is free of cancer cells. The neck is often included too, because tongue cancer can reach the lymph nodes (small glands in the neck) before anything can be felt.
Who this operation is not for
It is not the first step for every tongue cancer. Where the cancer has grown into the jawbone or far down the throat, or has spread beyond the neck, a different plan is usually discussed. That decision belongs to your treating team, and this page cannot make it for you.
Tell your surgeon about every medicine you take, including blood thinners. Do not stop anything on your own.On the day
What happens from the anaesthetic room to the ward?
Going to sleep
You are given a general anaesthetic. Because the surgeon works inside the mouth, the breathing tube usually goes through the nose, or a temporary opening is made in the neck.
Removing the cancer
A small cancer at the side of the tongue is removed through the open mouth. One further back may need a cut under the chin or the jaw opened to reach it. The tissue goes straight to the laboratory.
Clearing the neck
If planned, the lymph nodes are removed through a cut along a skin crease in the neck. A small drain stops fluid collecting.
Rebuilding the tongue
A small gap is stitched closed. A larger one is filled with skin and tissue from the forearm or thigh, joined to blood vessels in the neck under a microscope. This is what makes the operation long.
Waking up
You wake in a high-dependency bed with a feeding tube through the nose. You will not be able to talk at first. Your family is told as soon as the operation is over.
Not sure whether this applies to you?
Ask an oncologistOften part of the same operation
What else may be done while you are asleep?
A glossectomy is rarely a single procedure. These four are commonly added.
Neck dissection
Removal of lymph nodes on one or both sides of the neck. It leaves a neck scar and some shoulder stiffness for a while, and tells the team whether the cancer had started to spread.
Usually done when
- The cancer has grown deep into the muscle
- A scan shows a suspicious node
Tracheostomy
A short-term breathing opening in the front of the neck, made when swelling in the mouth could block the airway. It is usually temporary and closes on its own once removed.
Feeding tube
A thin tube through the nose into the stomach, so you can be fed while the mouth heals. After very large operations a tube straight into the stomach may be placed instead.
Flap reconstruction
Rebuilding the tongue with tissue from the forearm, thigh or chest. The donor site has its own wound. Ask your centre which team does this part.
On your papers
Which words will you see on the consent form and report?
- Partial glossectomy
- Removal of a piece of the tongue, usually less than half. The most common form.
- Hemiglossectomy
- Removal of one half of the tongue, split down the middle.
- Total glossectomy
- Removal of the whole tongue. Uncommon, and kept for cancers that fill most of it.
- Margin
- The rim of normal-looking tissue removed around the cancer. A clear margin means no cancer cells were found at the edge.
- Depth of invasion
- How far down into the muscle the cancer had grown. It helps decide whether the neck is also treated.
- Free flap
- Tissue moved from another part of the body with its own blood vessels, joined to vessels in the neck.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Did you know
The tongue is almost entirely muscle. What remains after surgery learns new movements over the following months, which is why speech and swallowing usually improve well beyond the first week.
Commonly believed
What do families believe about tongue surgery that is not true?
"If they cut the tongue, he will never speak again."
After a partial glossectomy most people speak clearly enough to be understood, with some speech therapy. Speech is harder after larger operations, and that should be discussed before you consent.
"It is only a small ulcer, so a small cut will do."
The ulcer is the top of the cancer, not the whole of it. Taking less to keep the operation small is how cancer is left behind.
"Radiation would be gentler than surgery."
For most tongue cancers that can be removed, surgery comes first, and radiotherapy is added only if the report shows a reason. Radiotherapy to the mouth has lasting effects on saliva and taste. Neither option is the gentle one.
"We should wait until after the wedding."
Tongue cancer can grow quickly, and a delay can change which operation is needed. Ask your surgeon plainly how much time you have, rather than deciding at home.
Being straight with you
What can this page not tell you?
This page describes the operation in general. It cannot tell you how much of your tongue will be removed, whether your neck will be included, or whether you will need a flap. Those answers come from your own scans and biopsy, and your surgeon should give them to you before you sign.
It cannot tell you what comes after
Whether radiotherapy or chemotherapy follows depends on the pathology report, which takes several days: the margins, the depth, and whether any neck nodes held cancer. Nobody can tell you this on the day of surgery.
What to ask at the consent appointment
Ask which type of glossectomy is planned and why. Ask whether the neck will be operated on, and whether a tracheostomy, feeding tube or flap is expected. Ask roughly how long you will stay in hospital. Write the answers down, and bring the family member who will care for you at home.
Questions we are asked
Common questions about glossectomy surgery
How long does the operation take?
It depends on what is planned. Removing a small cancer at the front of the tongue is fairly short. A neck dissection makes it longer, and a free flap makes it a long day in theatre. Your surgeon will give you a rough idea once the plan is fixed, so the family knows when to expect news.
Will I be awake for any part of it?
No. The whole operation is done under general anaesthetic and you will have no memory of it. You may wake with a breathing tube or tracheostomy that stops you speaking. The nurses expect this and will give you a pen and paper or a board to write on.
How long will I be in hospital?
A small partial glossectomy without a flap may mean only a few nights. With a neck dissection, tracheostomy or flap, the stay is much longer, because the team must see that the flap is healthy and that you can breathe and manage feeding before you go home.
Will I be able to eat afterwards?
Not by mouth at first. You are fed through a tube so the stitches are not disturbed. Swallowing is then re-learned in stages, starting with liquids, guided by a swallowing therapist. Most people after a partial glossectomy return to a soft, then a normal, diet.
Is the scar visible?
Surgery through the mouth leaves no scar on the face. A neck dissection leaves a line along a skin crease that fades with time. If the jaw has to be opened, there is a scar under the chin and lip. Ask your surgeon to show you where each cut will be.
Can this be done with a laser or a robot?
Some small tongue cancers can be removed with laser or robot-assisted instruments through the mouth, and some cannot. The tool matters far less than removing the cancer with a clear margin. Ask your centre what they use, why it suits your cancer, and what the alternative would be.
Will I need radiotherapy as well?
Possibly, but nobody can say until the pathology report is back. It is usually recommended if the margins are close, the cancer was deep, or cancer was found in the neck nodes. If the report is clear on all counts, many people need only regular check-ups.
Is this covered by Aarogyasri or my insurance?
Tongue cancer surgery is usually covered as part of an approved treatment plan. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. Call the helpline with your card details and biopsy report and we will check your cover before you travel.
