The parotid gland is the largest of the salivary glands. There are two parotid glands, one on each side of the face, just below and to the front of the ear. A duct through which saliva is secreted runs from each gland to the inside of the cheek.The main purpose of parotidectomy is to remove abnormal growths (neoplasms) that occur in the parotid gland. Parotid gland neoplasms may be benign (approximately 80%) or malignant. Tumors may spread from other areas of the body, entering the parotid gland by way of the lymphatic system.
