Deviation topographic map between unaffected contralateral facial contour and exenteration side of Case 1.

Deviation scale (left, mm) denotes measured deviations, from blue (symmetrical), to red (maximal deviation observed). Prostheses were made to cover all periorbital areas in which the deviation score was above 2.0 mm, with pointed exceptions. Minimal deviation occurs between yellow and light blue boundary at the temporal orbital rim (black arrowhead) denoting the lateral edge of the prosthesis. The white arrowhead pointing to the green shaded band indicates that there is minimal deviation from the contralateral side of the face. The black arrow pointing to the red shaded region indicates that there is substantial deviation; the prosthesis edge must cover all the red-shaded region and extend to the tip of the black arrow. This digitally-determined edge will be integrated into the design of the mold for the final prosthesis as the edges must be carefully curved inward to effect a smooth interface with the skin.
