Paradoxical masseter muscle hypertrophy (PMMH) 1-2 weeks after Botox to masseters.
Why it happens
1. Partial denervation
• Botox weakens some fibers, but not all
• Remaining fibers overcompensate → hypertrophy
2. Uneven injection pattern
• Deep vs superficial imbalance
• Missed posterior or inferior fibers
3. Dose too low for muscle size
• Common in strong bruxers / square jaw patients
4. Anatomy variability
• Masseter has multiple compartments
• If only one layer is treated → others enlarge
⸻
How to fix it
1. Touch-up Botox
• Inject the bulging segment specifically
• Usually:
• 5–15 units per side (targeted)
• Focus on deep + superficial layers of the bulge
• Improvement seen in 2–4 weeks

Europe 2023 what an amazing trip! So many great memories especially when Leo started walking in Switzerland 🇨🇭😃 Leo was truly a trooper going from London to Switzerland to Italy to Paris then back to London. This was actually his second time in Europe because the first time was when I was pregnant with him. Can’t wait for our next trip!
