What is the value of resection in high risk (but small or early stage) skin cancers at the medial canthus?

Is modern surgical/reconstruction treatment superior to radiation therapy? If contact brachytherapy or superficial (orthovoltage) therapy isnt possible, what is the preferred method? What dose/fractionation is preferred for contact brachytherapy. This is a difficult area for the classic leipzig applicators due to the contour of the nose/orbit. Would HDR catheters mounted to a mask in a Freiburg Flap be acceptable? What dose and depth would be preferred/ What dosimetric parameters or coverage goals would be considered necessary for ensuring that radiotherapy is a reasonable low morbidity alternative to resection.
