Abstract：
BACKGROUND: Transoral robotic surgery (TORS) for tongue base lesions located above the operative field is predominantly an upward procedure, which makes surgery difficult.
METHODS: To illustrate our technique for this procedure, we report the case of an 82-year-old male with a p16-negative oropharyngeal carcinoma of the tongue base who underwent TORS. The field of view was turned upside down, and the operation switched the typical left- and right-arm functions. The daVinci Xi was docked, the 0° endoscope was rotated 180°, and the first arm was switched to the right hand and the third arm to the left hand.
RESULTS: Although the lesion extended from the tongue base to the soft palate and mobile tongue, the planned resection line was followed.
CONCLUSIONS: This technique improves operability by allowing downward manipulation and preventing the left and right arms from crossing. Further validation of the technique\'s effectiveness and safety is needed.

摘要：
背景：位于手术区域上方的舌根病变的经口机器人手术（TORS）主要是向上手术，这使得手术变得困难。
方法：为了说明此过程的技术，我们报道了一例82岁男性患者,患有p16阴性舌根口咽癌,并接受了TORS治疗.视野被颠倒了，操作切换了典型的左臂和右臂功能。达芬奇号被停靠,0°内窥镜旋转180°，第一臂切换到右手，第三臂切换到左手。
结果：尽管病变从舌根延伸到软腭和活动舌，遵循计划的切除线.
结论：该技术通过允许向下操纵和防止左右臂交叉来提高可操作性。需要进一步验证该技术的有效性和安全性。
