Abstract
Background Traditionally, total thyroidectomy was performed through an open transcervical incision; in cases where there was evident nodal metastasis, the conventional surgical approach was to extend the incision into a large single transverse incision to complete the required neck dissection. However, recent innovation in the surgical technique of thyroidectomy has offered the opportunity to reduce the patient’s burden from these prominent surgical scars in the neck. Minimally invasive surgical techniques have been developed and applied by many institutions worldwide, and more recently, various techniques of remote access surgery have been suggested and actively applied.1, 2, 3, 4, 5, 6 Since the advent of robotic surgical systems, some have adopted the concept of remote access surgery into developing various robotic thyroidectomy techniques. The more former and widely acknowledged robotic thyroidectomy technique uses a transaxillary (TA) approach, which has been developed by Chung et al. in Korea.7,8 This particular technique has some limitations in the sense that accessing the lymph nodes of the central compartment is troublesome. Terris et al. realized some shortcomings of robotic TA thyroidectomy, especially in their patients in the United States, and developed and reported the feasibility of robotic facelift thyroidectomy.9, 10, 11, 12, 13 In cases of thyroid carcinomas with lateral neck node metastases, most abandoned the concept of minimally invasive or remote access surgery and safely adopted conventional open surgical methods to remove the tumor burden. However, Chung et al. have attempted to perform concomitant modified radical neck dissection (MRND) after robotic thyroidectomy through the same TA port.14 This type of robot-assisted neck dissection (RAND) had some inherent limitations, due to fact that lymph nodes of the upper neck were difficult to remove. Over the past few years, we have developed a RAND via modified facelift (MFL) or retroauricular (RA) approach and reported the feasibility and safety of this technique.15, 16 Since then, we have actively applied such RAND techniques in various head and neck cancers. In our country, almost all cases of robotic total thyroidectomy utilize the TA approach. According to the reports made by Terris et al., robotic facelift thyroidectomy technique has been solely applied for ipsilateral hemithyroidectomy. For total thyroidectomy, Terris et al. performed the robotic surgery with bilateral RA incisions. Here, we intend to introduce our novel surgical method after successfully attempting simultaneous robotic total thyroidectomy and RAND via a single RA approach without an axillary incision. To our knowledge, this is the first to report in the medical literature.
