Typically ~20–30 units per side (Botox units) to start, individualised to muscle bulk. Palpate while the patient clenches, inject deep to bone across 2–3 points inside the safe zone — stay behind the anterior border and below a line from the tragus to the mouth corner to avoid the risorius and an awkward smile. Counsel that slimming builds over weeks, first-timers can get transient chewing fatigue, and repeat sessions are usual. Great for bruxism/TMJ symptoms too.
