Table 2

Parotid gland radiation dose of two groups of patients.

Parotid irradiation dose	3D-CRT group ()	IMRT group ()
Average irradiation dose (Dmean, Gy)			9.6396	<0.0001
Maximum irradiation dose (Dmax, Gy)			7.1301	<0.0001
Minimum irradiation dose (Dmin, Gy)			15.5984	<0.0001
V20%			4.9013	<0.0001
V30%			7.3051	<0.0001
V40%			6.5665	<0.0001
