Chest reconstruction surgery would also include breast reductions. So, trans men. That’s who don’t like breasts. On themselves, anyway.
I’m speculating but I’d assume “reconstruction” since they are keeping and sometimes re-using existing tissues. Someone gets facial reconstruction, not construction, if e.g. they get mauled in an animal attack. You are restoring things to what the patient is comfortable with. A trans person may not have been injured but what they want is for their body to be fixed.
