Abstract

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.
