Establishing the robotic surgery procedure and techniques for head and neck tumors: a single surgeon's experience of 945 cases

We suggested operative techniques and indications of robotic neck surgery. To determine operative techniques and the indications for robotic neck surgery, we analyzed treatment outcomes of patients who received robotic neck surgery. Between May 2010 and July 2018, a total of 945 patients with various neck diseases visited Severance Hospital and underwent robotic neck surgery. A variety of approaches, including the retroauricular approach (RA), modified facelift approach (MFLA), transaxillary approach (TA), and transaxillary retroauricular approach (TARA), was used to remove various tumors in the neck. A total of 235 patients underwent a robotic neck dissection (elective or therapeutic) in the treatment of head and neck cancer with metastatic cervical lymph nodes. Five hundred-seventeen patients underwent robotic thyroidectomy or parathyroidectomy for thyroid or parathyroid disease, respectively. The remaining 193 patients underwent robotic neck surgery in the treatment of other neck diseases. Various neck lesions were successfully excised using RA or MFLA (including salivary gland tumors, thyroid tumors, vascular tumors, neurogenic tumors, lipomas, lymphangiomas, venous malformations, dermoid cysts, and others). Robotic neck surgery is a feasible and safe technique for the resection of various head and neck tumors. This method could be particularly useful in young patients with thyroid tumors, salivary gland tumors, and vascular tumors, among others, because it does not leave a visible scar on the face or neck. The superior visualization and articulate robotic arm that moves freely at various angles allows surgeons to perform delicate and precise surgeries.
