title: Accessory parotid gland tumors: A series of 4 cases.
abstract: Accessory parotid gland tumors are clinically rare, and their management remains unclear. In this article, we describe our experience with 4 patients-2 males and 2 females, aged 13 to 66 years-who were diagnosed with an accessory parotid gland tumor. All patients presented with an asymptomatic midcheek swelling, and all underwent fine-needle aspiration biopsy, ultrasonography, computed tomography, and magnetic resonance imaging. A standard parotidectomy was performed on all patients. Postoperatively, 2 patients were found to have a malignant tumor, while the other 2 had a pleomorphic adenoma. No patient experienced any obvious facial nerve injuries postoperatively, and no recurrences were observed. We discuss the preoperative evaluation, treatment, and prognosis of these tumors, and we briefly describe the literature. The first choice of treatment for accessory parotid gland tumors is surgical resection. In our experience, a standard parotidectomy approach is safe and cosmetically appealing.
