The differential diagnosis for recurrent parotid gland swelling includes autoimmune “pseudosialectasis” and Mikulicz syndrome. For most parotid tumors, surgeons may cut away the tumor and some of the healthy parotid gland tissue around it (superficial parotidectomy). Removing all of the parotid gland. Surgery to remove all of the parotid gland (total parotidectomy) might be recommended for larger tumors and those that affect the deeper parts of the parotid gland. 1.
