Chin wing or sliding genio: does it disrupt the mentalis muscle?

Does the chin wing or genioplasty disrupt the mentalis muscle ?

yeah tell us chin-wingers, did you have a problem?

Does the chin wing disrupt the mentalis muscle origin at the sulcus? Since an intraoral approach is used this almost makes me think with certainty that it would, but does anyone have more input in this? Apparently the mentalis muscle origin is very important for remaining lip posture, fullness of the lower lip, etc. Since I've seen so many complaints about the lower lip and how it appeared smaller after chin wing and given the intraoral approach that is used, it makes me think the mentalis muscle origin at the sulcus may be disrupted?

Normal genio's make the lower lip look smaller, but they usually go back to their normal size after a few months which will be the same for the chin wing

Chin nerd here, I could be wrong but I believe you're referring to the mentalis INSERTION around the gingiva vestibule.  The mentalis origin is connected to the menton (chin bone region). It's amazing I have issues with my mentalis muscle in that it makes my center lower lip too BIG, like it's creating an inverted V, yet if anything, only my mentalis origin could have been transected in surgery (submental chin implant approach).
