No significant differences were detected for the optic nerves ( p > 0.05), while the optic chiasm PRV showed a trend toward reduction (−5.6%, p = 0.040).

Rectum D10 cc decreased by ≈6% ( p = 0.040), and although V60 Gy reduction did not reach statistical significance ( p = 0.07), the direction favored RAD.
The mean heart dose was also reduced by approximately 25%, with a corrected p = 0.024, representing a strong trend toward significance, while the ipsilateral lung V20 did not differ significantly between techniques ( p = 0.48), see Table 3 .
After Bonferroni correction ( m = 3; adjusted α = 0.0167), both parameters remained trending toward significance, indicating a consistent improvement in parotid sparing.
