Overview of the condition
The Parotid gland is the largest salivary gland and is found in front of the ears and behind the jaw. This gland has the facial nerve running through the middle and this nerve controls the muscles of the face. The gland also contains lymph nodes.
Most salivary gland tumours occur here and the majority of these are benign, although they do present a small risk of becoming cancerous. The gland is also an area where skin cancers from the scalp and ear can spread to.
A parotidectomy is a procedure performed to remove all or part of the parotid gland with the goal of preserving the facial nerve.
Other salivary glands include:
- The Submandibular gland, which is the second biggest of the salivary glands and is found in the upper neck just under the jaw line.
- The Sublingual gland, which is located in the floor of the mouth on either side of the tongue.
- Tumours in these two glands are less common but are more likely to be cancerous.
Most salivary gland tumours are non-cancerous and are usually found in the parotid glands. Cancerous tumours of the salivary glands are either primary (originating in the gland) or secondary (having spread there from another part of the head and neck, usually the scalp). Cancerous tumours require an additional procedure to remove the lymph nodes from the neck.
Types of salivary gland surgery include:
- Partial parotidectomy – where only part of the gland is removed, preserving the facial nerve.
- Total parotidectomy – where all of the gland is removed and the facial nerve is preserved
- Radical parotidectomy – where all of the gland and the facial nerve are removed together. This is performed when the cancer has surrounded the facial nerve and this cannot be safely preserved.
- Neck dissection – where lymph nodes are removed from the side of the neck where cancer is at risk of spreading.
- Facial Reanimation – where part of the function of the facial muscles is reconstructed when the facial nerve has been removed.
- Submandibular gland and sublingual gland surgery – where these glands are removed either through the neck or the mouth
