Parotid tumors are abnormal growths that develop in the parotid gland. The parotid gland is the largest salivary gland in the human body. It is located in front of the ear and extends to the angle of the jaw. This gland plays an important role in producing saliva, which helps in digestion and keeps the mouth moist.
During early embryo development, the parotid gland forms close to lymph nodes and the facial nerve. Because of this, the gland in adults is closely connected with the facial nerve. The facial nerve controls facial movements such as smiling, blinking, and speaking. This close connection makes parotid tumor surgery a delicate procedure.
About 85% of parotid tumors are benign, which means they are non-cancerous. The remaining 15% are malignant, meaning they are cancerous. Even though most tumors are benign, they often need surgical removal because they can continue to grow and may sometimes turn into cancer.
What Is a Parotid Tumor?
A parotid tumor is a growth that forms in the parotid gland. These tumors can be benign or malignant.
Most patients notice a painless lump near the ear, cheek, or jaw. The lump may grow slowly over time. In some cases, symptoms may also include facial weakness, pain, or swelling.
Doctors usually recommend parotid tumor surgery to remove the tumor and prevent complications.
What Are the Common Types of Parotid Tumors?
There are several types of parotid tumors. The most common one is pleomorphic adenoma, also known as a benign mixed tumor.
Pleomorphic Adenoma
This is the most common benign tumor of the parotid gland. It usually grows slowly and has well-defined edges. Even though it is not cancerous, it can become large if left untreated.
In some cases, this tumor may turn into cancer after many years. This condition is called carcinoma ex-pleomorphic adenoma.
Warthin’s Tumor
Another common benign tumor is Warthin’s tumor. It is also called papillary cystadenoma lymphomatosum. This tumor usually appears in older adults and may occur on both sides of the parotid gland.
Other Benign Tumors
Other types of benign tumors include oncocytomas and monomorphic tumors. These tumors are rare but are usually treated successfully with surgery.
Hemangiomas
Hemangiomas are tumors made of blood vessels. They are the most common parotid tumors in children.
Benign Lymphoepithelial Lesions
These tumors are often seen in people with HIV. They may cause repeated cyst formation and swelling.
What Are the Symptoms of a Parotid Tumor?
Many people first notice a lump near the jaw or ear. The symptoms may vary depending on the type and size of the tumor.
Common symptoms include:
- Lump or swelling near the ear or jaw
- Slow growing mass in the cheek area
- Pain around the parotid gland
- Difficulty moving facial muscles
- Numbness or weakness on one side of the face
If a tumor presses on the facial nerve, it may cause facial weakness. This is why early diagnosis of parotid gland tumors is important.
How Are Parotid Tumors Diagnosed?
Doctors use several methods to diagnose parotid tumors.
First, the doctor performs a physical examination. They check the size, shape, and location of the lump.
Imaging tests are also helpful. These may include ultrasound, CT scan, or MRI. These tests help doctors understand the tumor size and its relation to nearby nerves.
Another common test is fine needle aspiration biopsy for parotid tumor diagnosis. In this test, a small needle is used to remove cells from the tumor. The cells are then examined under a microscope.
What Is Parotid Tumor Surgery?
The main treatment for most parotid tumors is surgery. The procedure used to remove the tumor is called parotidectomy.
During surgery, the doctor carefully removes the tumor while protecting the facial nerve. Because the nerve runs through the parotid gland, the surgeon must be very careful.
There are different types of procedures depending on the tumor location.
Superficial Parotidectomy
This surgery removes the outer part of the parotid gland. It is commonly used when the tumor is located in the superficial part of the gland.
Total Parotidectomy
In some cases, the entire gland may need to be removed. This is usually done for larger or cancerous tumors.
Modern surgical techniques aim to protect facial nerve function and reduce visible scarring. Some patients may also undergo parotidectomy with facelift incision technique, which helps hide surgical scars.
What Is Recovery After Parotid Tumor Surgery?
Most patients recover well after surgery. Hospital stay is usually short, and many patients return to normal activities within a few weeks.
Some temporary side effects may occur, such as mild swelling or numbness around the surgical area. In rare cases, facial nerve weakness may occur but often improves with time.
Doctors usually recommend follow-up visits to ensure proper healing and monitor for tumor recurrence.
When Should Someone See a Doctor?
Any lump near the ear or jaw should be checked by a doctor. Early diagnosis makes treatment easier and safer.
If a tumor is removed early, the chances of complete recovery are very high. This is why early treatment for parotid gland tumors is strongly recommended.
Parotid Tumor Treatment
Treatment depends on the type and stage of the tumor. Most benign tumors are successfully treated with surgery. Malignant tumors may require additional treatments such as radiation therapy.
