Possible side effects of surgery

The position of your cancer and the type of operation you have may affect you in one or more ways.

How you might be affected

Surgery for nasal and paranasal sinus cancer may affect you in one or more of the following ways:

  • the way you chew and swallow
  • your sense of smell
  • how you see
  • how you hear
  • how you speak

How you might be affected will depend on the position of your cancer and the type of operation you have.

These changes may happen because your face and neck are swollen and sore after surgery. They will usually reduce or disappear once you start to heal. Swelling might also change how you look, but this will usually get better too.

You might have some permanent changes in what you can do and the way you look. 

Before you have the surgery, your doctor will discuss the side effects with you.

Changes to your appearance

Surgery for nasal cavity or paranasal sinus cancer can change the way you look. How you look is an important part of your self esteem. It can be very hard to accept sudden changes in your looks that you are not happy with.

If you have had facial surgery, it might be hard to look at yourself in the mirror at first. You might feel very angry, confused and upset for some time afterwards. Before your operation you will see your specialist head and neck nurse. They will discuss all the possible changes to your appearance and how these might make you feel. 

It can be very upsetting to go through a cancer diagnosis and then a big operation that changes how you look. You are likely to have times when you feel very down. Try to take time to recover fully from the operation. You’ll need a lot of support from your doctors and nurses, and your family and friends. So lean on them for help as often as you need to.

Temporary changes in how you breathe

Some surgery can temporarily affect how you breathe. You might have reconstruction to part of your face with a tissue flap. This means that you might need to breathe through a tube in a hole in your neck. You do this until the wound has healed. The hole in your neck is called a temporary breathing stoma or tracheostomy.

Changes to speech, chewing and swallowing

Your surgeon will always try to avoid changes to your speech, chewing or swallowing as much as they can. Sometimes this isn't possible, and you will need to deal with changes after the surgery. This can be very hard to deal with, but there are things that can help.

Loss of sense of smell

Your sense of smell will decrease after some types of surgery. This is especially if you had your nose packed after the surgery. Once the pack comes out, it might improve. But it can take up to 3 months for your sense of smell to come back. If you had little or no sense of smell before your operation, losing your sense of smell may be permanent.

It can be difficult to cope with not being able to smell.


Parts of your face might be numb after surgery. The numb areas might include the tip and side of your nose, cheek, upper lip or gums. The sensation usually comes back after a few weeks. But sometimes it can take several months or might be permanent. Not being able to feel parts of your nose, cheek or mouth can be difficult to cope with.

Changes to your eyesight

If your surgery affects the eye socket, you might have swelling and bruising around the eye. This is usually only a temporary problem. In some situations the surgeon needs to remove the eyeball. This will cause changes in your eyesight. These changes can be hard to cope with. 

Changes to your hearing

Sometimes the swelling caused by surgery can reduce your hearing. This is usually only a temporary problem while you recover. Your hearing should get back to normal when the swelling goes down.

Lymphoedema (swelling)

After surgery to remove lymph nodes from your neck, you are at risk of getting lymphoedema in your neck or face.

Lymphoedema in the head or neck can also cause symptoms inside your mouth and throat. This may include swelling of your tongue and other parts of your mouth.

Tell your doctor if you have:

  • any swelling or a feeling of fullness or pressure
  • find it difficult to swallow
  • have changes in your voice

Using your head, neck and shoulder muscles may help to reduce swelling. Your physiotherapist or specialist nurse will usually go through these exercises with you. 

These exercises shouldn't be painful. You might have a feeling of stretching as you do them, this is normal. Stop doing the exercises if you have any pain and, if doesn't get better contact your doctor.

Do the exercises slowly and gently, don't rush them. You can rest between exercises. It might help to do them in front of the mirror so you can check that your shoulders are back and relaxed.
