those airtubes which don't seem to serve any purpose

TIE Fighter pilots in the OOT also have airtubes.

The difference being that those airtubes are connected to an airtight spacesuit instead of to...the side of his face? Does he have little auxiliary mouths on either side of his main mouth for air? Is he an aquatic creature with gills? It could work I guess, it just seems kind of awkward.

But Duracell was asking what the purpose of the tubes is, not how Cad inserted them into his face.
