Thank you for your excellent question that will help patients with large masseter muscles who are considering a longer term solution for a slimmer jawline.
How effective is radiofrequency treatment for masseter reduction?
Published studies indicate that the efficacy of radiofrequency masseter reduction is pretty much equivalent to botulinum toxin masseter reduction after six months. Both can produce approximately 50-60% reduction in the thickness of masseter muscles. However, unlike botulinum toxin which only lasts for six months, the effect of radiofrequency masseter reduction is sustained even after 12 months. However, there haven't been sufficient long term studies published to conclude that the reduction is permanent.
Masseter reduction (in this case using botulinum toxin) can produce rather impressive results in the right patients (source)
Radiofrequency masseter reduction is not commonly done in Singapore as it usually has more downtime in the form of swelling and carries higher risks of (potentially serious) complications such as:
- Bruising and hematoma
- Fluid collections
- Late bleeding
- Infections
- Injuries to surrounding structures such as salivary duct, facial nerves
Most aesthetics doctors would prefer to use botulinum toxin as there is little to no downtime, minimal risk of complications and much less technically demanding.
Do consult a doctor who will be able to explain the pros and cons of each to you in detail.
Hope this helps!
Warmest regards,
Dr Wan Chee Kwang
