Mixed parotid tumors are most often seen in young adults and the tumor is located just below the earlobe. When it is large, it extends to the neck. The tumor is in the form of a hard nodule, sometimes part of it develops cystic degeneration with softer nodules in between. The tumor can be pushed without adhesion to the skin or basal tissues; it grows slowly and remains unchanged for several years or more than ten years. If malignant transformation occurs, the tumor often grows suddenly and rapidly and adheres to the surrounding tissues and becomes fixed. In the advanced stage, the malignant tumor may ulcerate and symptoms such as pain or facial nerve paralysis may appear. There are also lymph node metastases in the lateral neck region. If one of the following situations occurs in the tumor, the possibility of malignant transformation should be considered: 1, the tumor grows suddenly and rapidly, 2, the mobility decreases or even becomes fixed, 3, pain or facial paralysis occurs, etc. The treatment of parotid mixed tumors is based on the principle of complete surgical resection. Preoperative biopsy is generally not suitable. Sometimes tumor cells may invade into the pericardium or extrapericardial tissues, and if the resection is not complete, the tumor will recur. Therefore, it is not suitable to remove the tumor by plucking out the tumor, but to remove the tumor together with the surrounding parotid tissue. During the operation, attention should be paid to the protection of facial nerve, and malignant changes should be treated according to the principles of malignant tumor treatment. If the deep lobe of the parotid gland needs to be removed, the main trunk and branches of the facial nerve should be exposed and carefully separated. Radical total parotidectomy including the facial nerve branch should be performed if malignancy is present.
