In what situations (if any) would you recommend ENI for a low grade parotid mucoepidermoid carcinoma?

Not sure if I understand the question correctly but I will give the best answer I can. There aren’t many reasons to treat low-grade parotid mucoep. If you’re treating for positive margins only, I wouldn’t do ENI. If you’re treating for PNI, cover nerves to skull base. If there are positive nodes, treat the involved neck, preauricular nodes, postauricular, and 1 level inferior to the involved level, and spare levels IA and IB. Involved levels get 60Gy, 66Gy if ENE, 54Gy if ENI.

I will never treat neck electively in low-grade mucoepidermoid carcinoma of the parotid. The risk of occult nodal metastasis in low-grade mucoepidermoid cancers of major salivary glands is extremely low.
