Can screws be taken out out after sliding genioplasty without cutting the mentalist muscles again?

Small screws after genioplasty are very rarely removed; it has to be a good reason like visible, palpable deformity, which is very rare with that size of screw? However, if needed, removal should be done using already existing incision/scar inside the mouth or underneath the chin. In that case temporary damage to the mental is muscles may be seen.
