Dunlap Q, Mitchell WM, Gardner JR, et al. - Researchers studied the effect of lingual artery ligation on tongue vascularity in 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 as a surrogate for vascularity in postoperative imaging (mean 4 months). Ligation resulted in a significant reduction in IM measurements but no difference between GG values vs nonligated patients. There was no discernible difference in mean values for combined IMs and GGs between cohorts. There was no significant tongue atrophy or complications.
