Twenty-six patients with T1-3N0-1M0 disease underwent supraomohyoid neck dissection between 2018 and 2023 (13 robotic, 13 open). Perioperative outcomes, including hospital stay, drainage duration, complications, and lymph node yield, showed no significant differences (median lymph nodes: 20 vs. 21; p = 0.950). During a median follow-up of 743 days, no recurrences or deaths occurred. In the last five robotic cases, a third instrument (ProGrasp Forceps) was added without increasing operative time (p = 0.803) . Robotic-assisted neck dissection via the retro-auricular route is a safe and effective alternative for early stage oral cavity cancer patients, particularly those with clinical N0 disease, preserving oncologic outcomes while improving cosmetic appearance.  \nKeywords Robotic surgery · Neck dissection · Oral cancer · Retro-auricular  \nIntroduction  \nThe neck region contains abundant lymphatic circulation, making it a common pathway for the metastasis of upper aerodigestive cancer cells to cervical lymph nodes. Even in patients with early stage oral cavity cancer, who show no apparent lymphadenopathy, approximately 15–20% may have occult lymph node metastasis in the ipsilateral neck.  \nWen-Chun Lin and Man-Wei Hua are co-first authors/contributed equally to this work.  \n* Chen-Chi Wang[entccwang@msn.com](entccwang@msn.com)  \n1 Department of Otorhinolaryngology Head and Neck Surgery, Taichung Veterans General Hospital, 1650, Section 4, Taiwan Boulevard, Xitun Dist., Taichung 407219, Taiwan  \n2 Department of Post‐Baccalaureate Medicine, College of Medicine, National Chung Hsing University, Taichung, Taiwan  \n3 School of Medicine, Chung Shan Medical University, Taichung, Taiwan  \n4 Institute of Clinical Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan  \n5 School of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan  \nWithout dissection and pathological examination of highrisk neck lymph nodes to determine the true N-status, metastatic lymph nodes that are detectable only under a microscope can be easily overlooked [1] . This can lead to local recurrence of head and neck cancer, posing life-threatening risks.  \nIn the past decades, patients with clinical N0 oral cavity cancers have undergone conventional open neck dissection to confirm their N-status. Approximately 70% patients of these patients were found to have pN0 results after surgery but endured visible neck scars. This issue is particularly significant for patients prone to keloids, where psychological stress related to surgical scarring often leads to fear of surgery and reduced satisfaction. Some authors have proposed prophylactic radiation therapy to the ipsilateral neck, which avoids visible scarring but introduces long-term adverse effects such as hyperpigmentation, muscle fibrosis, and carotid artery stenosis [2, 3] .  \nHistorically, head and neck surgeons have been hesitant to adopt traditional endoscopic techniques via hidden remote incision due to the complex anatomy of the region, which poses challenges in access and visualization. However, recent advancements in surgical techniques such as robotassisted surgery have emerged to offer endoscopic approach with efficacy comparable to open surgery. Studies have demonstrated that robotic-assisted neck dissection not only  \nFig. 1 The retro-auricular incision extends superiorly from ear lobe to mi","cbCaif9v2cwQY81q","https://ap.wps.com/l/cbCaif9v2cwQY81q","pdf",1396634,"English","# Abstract\n# Introduction\n# Materials and methods\n## Patients","[{\"question\":\"Who were included in this study and what cancer stage criteria were used?\",\"answer\":\"The study included 26 patients with T1-3N0-1M0 early stage oral cavity cancer undergoing supraomohyoid neck dissection between 2018 and 2023.\"},{\"question\":\"How did robotic retro-auricular dissection compare with conventional open surgery in perioperative outcomes?\",\"answer\":\"Perioperative outcomes such as hospital stay, drainage duration, complications, and lymph node yield showed no significant differences between robotic and open approaches.\"},{\"question\":\"What were the follow-up results regarding recurrence and survival?\",\"answer\":\"During a median follow-up of 743 days, no recurrences or deaths occurred in the study cohort.\"}]","Comparable outcomes with improved esthetics - da Vinci-assisted neck dissection for early stage oral cancers | PDF",1790202220,23]
