The treatment of early parotid tumors is simply to remove the tumor. The consequence was recurrence of the tumor, especially the most common pleomorphic adenoma of the parotid gland, which is prone to recurrence because of extraperitoneal growth and simple removal of the tumor; in addition, because of unfamiliarity with the anatomy of the facial nerve, it is also easy to cause facial nerve injury resulting in facial paralysis. Later, with the deepening of the understanding of the disease and the improvement of medical technology, the classical parotid surgery method was developed, in which the peripheral branches or the general trunk of the facial nerve are dissected out first, and then the superficial lobe of the parotid gland or the entire parotid gland (depending on the location of the tumor) and the tumor body are removed together. This method can avoid the recurrence of the tumor and protect the facial nerve from damage, which obviously improves the treatment of parotid tumors and makes the treatment level of parotid surgery significantly better. However, over time, it has been found that if the tumor is small, removing the superficial lobe or the entire parotid gland is not only more damaging, but also increases the chance of facial nerve injury. Thus, in fact, there is a tendency to expand parotid surgery. In recent years, the drawbacks of classical parotid surgery have been gradually recognized, and a new view of focal resection of the tumor has been proposed. In other words, on the basis of anatomical protection of the facial nerve, only the tumor and the surrounding parotid gland are removed, while the parotid tissue distant from the tumor is preserved. This surgical approach can avoid the problem of postoperative recurrence, reduce surgical trauma, and preserve the function of the residual gland. Therefore, it is a reasonable and effective surgical approach. Of course, for different pathological types of tumors, the surgical approach may vary accordingly: for adenolymphoma (Worthing’s tumor), the lymph nodes surrounding the tumor should be removed together, because there may be ectopic glands or tumors in these lymph nodes; for malignant tumors, the tumor and all parotid tissue should be removed together. If there is preoperative facial palsy, highly malignant or adenoid cystic carcinoma (easy to grow along nerves and blood vessels) or if the tumor and facial nerve are closely adherent and cannot be separated, the facial nerve should be removed together to avoid postoperative recurrence and metastasis. For adenocarcinoma, squamous carcinoma, poorly differentiated or undifferentiated carcinoma, cervical lymphatic dissection should be performed at the same time or electively, depending on the situation.
