Among benign tumors in the parotid gland, Warthin's tumor, which ranks second in frequency, is associated with smoking. It is the most common bilateral and multisentric (multifocal) tumor. If a patient who develops Warthin's tumor in one parotid and continues to smoke, there is a possibility of Warthin's tumor developing in the opposite parotid. Warthin's tumor has no potential to turn into cancer. Its treatment is surgical. The tumor is removed through partial parotidectomy, which involves excising the tumor along with a small amount of healthy parotid tissue surrounding it. During the surgery, nerve monitoring is applied to help preserve the integrity of the facial nerve. However, it should be noted that the most important factor in preventing facial paralysis is for the patient to entrust themselves to a surgeon who is knowledgeable in anatomy and experienced in parotid tumor surgery.
