This leaflet has been produced to give you general information about your treatment. Most of your questions should have been answered by this leaflet. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team.
What is the parotid gland?
You have two parotid glands that are each about the size of a plum. They are positioned immediately below and in front of the ear. The saliva it produces passes through a tube that opens on the inside of the cheek next to the upper back teeth.
Why do I need treatment?
The most common reason for removing the parotid gland is because there is a lump or blockage of the gland. Lumps can occur due to abnormal growth of the gland. Most of the time, these lumps are benign meaning they do not spread to other parts of the body. However, occasionally cancerous tumours can affect the parotid gland. Other causes for blockages include salivary gland stones. Removal of the gland prevents lumps getting bigger or helps relieve discomfort caused by blockages.
Are there any alternatives and what would happen if I have nothing done?
If you have a stone in your parotid gland, sometimes it is possible merely to remove the stone. However, it is not always easy to reach the stone, especially if it is far back in the duct or in the gland itself. On many occasions the gland may be considered to be too diseased to be left. If ignored you may have further episodes of pain and infection which if severe can be life-threatening. However, this is rare.
Can there be any complications or risks?
There are complications and risks of this surgery and it is important that you are aware of these and have the opportunity to discuss them with your surgeon.
The facial nerve runs through the parotid gland and makes the muscles move on that side of your face. Sometimes the nerve can become bruised from the surgery, meaning the movements of you face can be weakened. If this happens, in most cases the nerve fully recovers over time. However, there are a small number of cases which result in permanent weakness of the face muscles.
There will be numbness of the skin particularly of the ear because the nerves supplying sensation are cut in the operation. Some of the numbness fades in the first year, but it is usual for numbness of the ear lobe to remain.
As nerves recover, some patients’ experience sweating or flushing of the skin over the gland especially, when they eat. This is called Frey’s syndrome.
There will be a scar but this is made as invisible as possible by placing incisions in skin creases. Initially a scar may appear red and lumpy but this tends to fade to a white line after six months or so.
Since part of or the entire gland is taken away it results in hollowing in front of and below the ear.
How do I prepare for the treatment?
Please read the information leaflet. Share the information it contains with your partner and family (if you wish) so that they can be of help and support. There may be information they need to know, especially if they are taking care of you following this examination.
You will be given a letter detailing where you should attend, starving instructions and the time to report to the ward. Staff will greet you and show you around the ward. You will be seen by the doctor and possibly the anaesthetist. The type of anaesthetic you will be having is called a general anaesthetic. You will be prescribed pain relief medication to manage any pain you may suffer following the operation.
You may be required to attend a pre-assessment where the nurse will prepare you for the surgery and you can ask any questions you may have. They will also ensure you are fit for the anaesthetic.
What does the operation involve?
The parotid gland is removed under a general anaesthetic i.e. you will be asleep during the operation. The operation involves a cut around two to three inches long immediately in front of the ear. This cut is extended downwards into the neck and possibly upwards to the temple, where it may be necessary to shave some hair. Once the gland has been removed the incision is held together with stitches. These usually need to be removed about a week after surgery. At the end of the operation a small tube is also placed through the skin into the underlying wound to drain any blood which may collect. This may be removed two to three days after the surgery.
Will anything else be done while I am asleep?
If your gland is being removed because of infection that is caused by a stone it may also be necessary to make a cut inside the mouth to remove that stone. If it is for a tumour, the lymph nodes which filter the lymph from the gland below the jaw may be removed in order to be examined.
How long will the operation take?
Removal of all or part of the parotid gland is a complicated operation which takes approximately three to four hours.
Do I need any time off work?
It is usual to take a week off work to recover from the surgery and possibly more depending on your job. You should avoid strenuous activity during this time.
Is there anything that I need to do when I get home?
It is important to keep the wound dry for the first week following surgery. This obviously means you need to take care when washing or shaving.
