Receiver operating characteristics (ROC) curves of grade ≥ 2 facial lymphedema according to mean level IV (a) and level I-VII (b) neck node dose in all patients (n = 87). Optimal cut-off mean dose of level IV neck node was 58.7 Gy (AUC: 0.726; 95% CI = 0.614–0.839, p = 0.001) and level I-VII neck node was 58.6 Gy (AUC: 0.720; 95% CI = 0.614–0.826, p = 0.001), respectively
