The warm zones are where you don’t want to be. This facial nerve course heatmap from Zhao et al.‘s 2026 cadaveric study on masseter anatomy makes the risk distribution visible in a way that no diagram or verbal description quite manages. The safe triangular zone △LMF — where the probability of hitting facial nerve, parotid structures, and facial vasculature is lowest — is the clinical payoff. Masseter Botox is routine until it isn’t.
