Although the search engines seem to tie "лицевые части" up only with gas masks :-( , I think the logic itself hints us that this is it, you're right.

Sorry, I change my opinion. This must be "surface parts". Look here:

The actual embalming process usually involves four parts:

arterial embalming, which involves the injection of embalming chemicals into the blood vessels, usually via the right common carotid artery. Blood is drained from the right jugular vein. The embalming solution is injected using an embalming machine and the embalmer massages the corpse to ensure a proper distribution of the embalming fluid. In case of poor circulation, other injection points are used;
cavity embalming, the suction of the internal fluids of the corpse and the injection of embalming chemicals into body cavities, using an aspirator and trocar. The embalmer makes a small incision just above the navel and pushes the trocar in the chest and stomach cavities to puncture the hollow organs and aspirate their contents. He then fills the cavities with concentrated chemicals. The incision is either sutured closed or a "trocar button" is screwed into place.
hypodermic embalming, the injection of embalming chemicals under the skin as needed; and
surface embalming, which supplements the other methods, especially for visible, injured body parts.
