Clinical and histological data, type of surgery, and complications were assessed and described.ResultsThe main manifestation was a mass with a median evolution of 12 months for benign tumors and five months for malignant tumors. Ultrasonography was the most frequent complementary exam. Pleomorphic adenoma was the most common of the benign tumors, and mucoepidermoid carcinoma was the most frequent malignant tumor. Superficial parotidectomy with preservation of the facial nerve was the most common surgical procedure and reversible paresis of branches of the facial nerve was the most common complication.ConclusionsPleomorphic adenoma is the most common parotid gland tumor and superficial parotidectomy with preservation of the facial nerve is the most common and appropriate treatment for most low-morbidity tumors
