Abstract
A 30-year-old female patient with a benign tumor in the superficial lobe of the left parotid gland underwent tumor resection via a 5 cm intra-hairline incision, using the da Vinci Xi surgical robot combined with the NIM-Response 3.0 facial nerve monitoring system. During the operation, facial nerve branches were located and protected through facial nerve monitoring, and the robotic arms were used for precise tumor dissection. Postoperatively, the facial nerve function, incision healing, and tumor recurrence were observed. duration of the procedure was 120 minutes, and the tumor（2.0 cm×1.5 cm） was completely resected. Postoperative pathological examination indicated a pleomorphic adenoma. During the 3-month postoperative follow-up, the patient's facial nerve function remained normal, no salivary fistula occurred, the incision was hidden within the hairline, no tumor recurrence was found in the ultrasound reexamination, and the patient was highly satisfied with the appearance. The surgical approach of robot-assisted resection of benign parotid gland tumor via a hairline incision under facial nerve monitoring has significant advantages in facial nerve protection and cosmetic effect, and is suitable for patients with benign parotid gland tumors meeting specific conditions.
