Comparison of two dosimetric plans for the same patient, using the same isocenter (8 arcs): 5-mm cone (left size) and 6-mm cone (right size). The total length of the nerve was 10.2 mm. The length of the nerve included in the isodose 45 Gy was 5.9 mm for the 5-mm cone and 6.9 mm for the 6-mm cone. The brainstem D0.035 was 13.3 Gy for the 5-mm cone and 20.2 Gy for the 6-mm cone
