Hint for homework:
1. In this case CTV66 was used to contour the area around the primary by the deep lobe of the parotid and
parapharyngeal space…CTV60 was used to treat the remaining lateral parotid tissue and to trace the facial nerve &
auriculotemporal (V3) nerve pathway
2. Use this excellent article by Ko et al to help you contour the facial nerve pathway on the right (A contouring guide
for head and neck cancers with perineural invasion, Practical Radiation Oncology (2014) 4, e247-e258)
