6 wks postop revision necklift fails to fix contour issue; PS agrees issue is digastric muscle prominence, not SMGs. Too full submental area and fat-free anterior neck shows musculature; swallowing reveals mechanics of neck function that should be hidden. Hollowed indents are uptucked under submental; digastrics converge to a point under chin. Pressing upwards into the bulging muscle makes submental flat and hollows vanish. Would reducing or removing muscle help? Risks? Experts input please.
