To explore the effect of lingual artery ligation on tongue vascularity, we performed an analysis of 25 patients who underwent transoral robotic surgery for base of tongue cancers (May 2011 to December 2019). Hounsfield units of the intrinsic muscles (IMs) and genioglossus muscles (GGs) were measured in postoperative imaging (mean 4 months) as a surrogate for vascularity. In ligated patients (n = 15), the values from the ligated/resected side of the tongue were compared with the contralateral side and the nonligated side of resection. Individually, IMs and GGs on the ligated side demonstrated no significant difference to the contralateral side ( = .662 and .618, respectively). Ligation produced a significant decrease in IM measurements but no difference between GG values vs nonligated patients ( = .050 and .818, respectively). No difference was appreciated in mean values for combined IMs and GGs between cohorts ( = .212). No gross tongue atrophy or complications were incurred. Future studies are warranted to delineate long-term effects.
为了探索舌动脉结扎对舌血管生成的影响，我们对 25 例接受经口机器人手术治疗舌根癌的患者进行了分析（2011 年 5 月至 2019 年 12 月）。术后影像学（平均 4 个月）测量固有肌（IMs）和颏舌肌（GGs）的亨氏单位，作为血管生成的替代指标。在结扎组（n=15）中，比较了舌结扎/切除侧的数值与对侧和非结扎切除侧的数值。单独来看，结扎侧的 IMs 和 GGs 与对侧相比无显著差异（分别为=.662 和.618）。结扎导致 IM 测量值显著降低，但 GG 值与非结扎患者无差异（分别为=.050 和.818）。两组的 IMs 和 GGs 平均值之间无差异（分别为=.212）。未发生明显的舌体萎缩或并发症。需要进一步的研究来阐明长期影响。
