BACKGROUND: This study aimed to evaluate the feasibility and effectiveness of ultrasound-guided charcoal tattooing in locating metastatic lymph nodes in robotic selective neck dissection (SND) for @entity3557 ( @entity3557 ). METHODS: The overall study group comprised 21 @entity1 with @entity3557 who underwent robotic SND via a unilateral transaxillary approach for treatment of suspicious lymph node @entity3 in the lateral compartment. Charcoal suspension was injected into 10 of the @entity1 (total of 23 lesions) 1 day before robotic SND. The authors evaluated the location of the tattoos, the success rate of localization, the intraoperative detection rate, and the complications associated with the procedure. The perioperative results were compared with those in the control group of 11 @entity1 who did not receive charcoal tattooing. RESULTS: Charcoal suspension was successfully injected into 22 of the 23 suspicious lymph nodes (95.7 %). The remaining lesion was located posterior to the internal jugular vein. Therefore, the @entity36592 was injected into the soft tissue around the lymph node. Ultrasound-guided injections were well tolerated in all the @entity1 , and no major complications occurred. All the charcoal-tattooed lesions were identified intraoperatively by the surgeon. The number of harvested and metastatic lymph nodes in the lateral compartment was greater in the @entity1 with charcoal tattoo localization than in the control group. The two groups did not differ in terms of perioperative complications, operation time, or volume of drainage. CONCLUSION: Ultrasound-guided charcoal tattooing for localization of metastatic lymph nodes is feasible and effective in robotic SND for the treatment of @entity3557 with lateral compartment lymph node @entity3 .
