The parotid glands are the largest of the salivary glands and are responsible for the production of saliva which aids in swallowing and digesting food. They can become infected, swollen, or malfunction. Parotid gland swelling can be due to both infections and cancerous or noncancerous tumors. These may require surgical treatment. This requires evaluation and management by an ear, nose, and throat specialist.
