Why are radiofrequency and HIFU not the same method?

Radiofrequency uses electrical energy while HIFU uses focused ultrasound; energy distribution, target depth, device control and evidence differ. Ultrasound, radiofrequency and thread procedures are not equivalent to one another or surgery; evidence is device- and material-specific.

This translation has no recorded clinical or medical-language review.

Direct answer

Radiofrequency uses electrical energy while HIFU uses focused ultrasound; energy distribution, target depth, device control and evidence differ.
Ultrasound, radiofrequency and thread procedures are not equivalent to one another or surgery; evidence is device- and material-specific.
Ask for exact device, intended layer, temperature or imaging control, subcutaneous-fat and nerve risks and alternatives.

Assessment framework

Questions for consultation

Ask for exact device, intended layer, temperature or imaging control, subcutaneous-fat and nerve risks and alternatives. Alternatives, the option of no procedure, material risks, follow-up and urgent warning signs should also be discussed individually.
