The bulk update request #10574 is pending approval.

create implication chin_scar (86) -> facial_scar (23804)
create implication mouth_scar (316) -> facial_scar (23804)
create alias lip_scar (246) -> mouth_scar (316)
create implication nose_scar (483) -> facial_scar (23804)

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.
