Step 2: Planning comparison

Estimation of dose difference (Δdose)

Standard IMRT:

Dose reduction parotid glands No dose constraints for SWOARs D mean superior PCM = 64 Gy D mean supraglottis = 60 Gy

Swallowing sparing IMRT (SW-IMRT) : Dose reduction parotid glands Dose reduction SWOARs D mean superior PCM = 54 Gy D mean supraglottis = 30 Gy
