At present, there is no authoritative conclusion that parotid tumor is cured if it does not recur for several years. If there is no recurrence 5 years after surgery, it can be regarded as clinical cure, but there is still a certain risk of recurrence, as follows. The treatment of parotid tumors is mainly based on surgery, in which most of the tumors have incomplete envelope, resulting in parotid tumors easy to recur. For those with incomplete surgical resection and tumor remnants, as well as those whose tumors are in close proximity to the facial nerve and whose facial nerve is preserved after surgery, the postoperative recurrence rate can be reduced by radiation therapy. If the parotid tumor does not recur within 5 years after surgery, then the chance of recurrence is not high and can be called clinical cure, but the tumor still has the possibility of recurrence. The prognosis of parotid tumor should be observed for more than 10 years. It is recommended to visit a regular medical institution to receive professional treatment.
