Surgery is necessary for a 2cm large mixed tumor of the parotid gland. Although most of the mixed parotid tumors are benign, there are more cases of potential malignancy, so surgery is generally recommended to completely remove the tumor to avoid the possibility of malignancy or recurrence in the later stage. Especially if the tumor is 2cm in size, it should be operated in time, and after the operation, the pathology section should be examined in order to clarify the benign or malignant nature. It should be noted that biopsy should not be done before parotid mixed tumor resection surgery, so as to avoid part of the tumor cells entering into the body tissues. Meanwhile, attention should be paid to preserving the facial nerve during the surgery to avoid adverse consequences in the later stage. After the surgery, try to eat a light diet, do not eat spicy and stimulating food, patients may have difficulty in opening their mouths and chewing because of the surgery, at this time, should take liquid food as the main. It is recommended that once the diagnosis of mixed tumor of parotid gland is confirmed, early surgical treatment should be actively carried out to avoid spreading and metastasis, and if there is any discomfort, it is necessary to consult a doctor in time.
