What is your preferred radiation therapy technique for treating resected neurotropic squamous cell carcinoma of the facial skin situated near the infraorbital foramen?  

We have no problems using electrons when targeting tissues <2 cm deep. We use internal tungsten eye shields with an aluminum backscatter cap which reduce transmission to <5% with electron beam energies up to 9 MeV. Shiu et al., PMID 8655385. Depending on the calibration of the machin...

If the eyelid is part of the target, I typically use electrons with internal eye shielding. If the eyelid is not part of the target, I typically use either intensity modulated photon or proton therapy.   Consideration also should be given to whether the infraorbital nerve is part of the targ...

I agree with Dr. @Christopher A. Barker. In addition, MR is helpful in evaluating and tracking the nerve.
