What is tumescent liposuction?

Tumescent liposuction relies on injecting a specialized fluid solution into the targeted fatty areas before aspiration begins. The solution typically contains normal saline, a local anesthetic (usually lidocaine), and epinephrine, a vasoconstrictor. This fluid causes the tissue to swell and become firm, which is where the term "tumescent" comes from.

The anesthetic component numbs the area, reducing pain during the procedure and often allowing it to be performed under local anesthesia rather than general anesthesia. The epinephrine narrows blood vessels in the region, which decreases bleeding and bruising during and after fat removal. The saline base hydrates the tissue and helps the solution spread evenly through the treatment zone.

By injecting this fluid first, surgeons can remove fat more precisely while minimizing trauma to surrounding tissues. The technique became standard in liposuction practice because it improves both safety and outcomes. Patients typically experience less post-operative pain, swelling, and discoloration compared to older dry or wet liposuction methods. The numbing effect also allows surgeons to work carefully and contour the area with greater control.

Tumescent liposuction is widely used in body-contouring procedures across Ontario. If you're considering this technique, speaking with a qualified plastic surgeon will help you understand how the approach applies to your specific goals.
