**Abstract**

This chapter will discuss the various energy-based modalities that are available to optimize circumferential trunk liposuction to enhance patient results. We will discuss multimodal liposuction using power assisted liposuction, ultrasonic energy addition, as well as radiofrequency assisted modalities to achieve adipose reduction and concurrent skin and soft tissue contraction. An in-depth look at patient selection and intraoperative technique will be presented. The postoperative management for each modality will be discussed in detail, including expected results from each modality and potential complications and their ensuing management. We will also discuss the application of different modalities alone and in combination to achieve superior results.

**Keywords:** ultrasound-assisted liposuction, radiofrequency assisted lipolysis, helium plasma focused radiofrequency liposuction, abdominal liposuction, energy-based liposuction
