The bulk update request #10574 is pending approval.

create implication chin_scar (77) -> facial_scar (22963)
create implication mouth_scar (307) -> facial_scar (22963)
create alias lip_scar (236) -> mouth_scar (307)
create implication nose_scar (462) -> facial_scar (22963)

Reason: Implying some currently unimplied types of facial scars.

lip scar seems to be indistinguishable from mouth scar, so aliasing to the more general term makes sense to me.
