Lipomas Treated with Subcutaneous Injections of Cooled Sodium Chloride

Summary

Lipomas are benign tumors composed of mature adipose tissue. While harmless, these are the most common type of soft tissue growths with some patients developing numerous lipomas. Patients often seek removal for cosmesis, or symptoms caused by location and/or compression of surrounding structures. This exploratory study aims to evaluate the effectiveness of subcutaneous injections of cooled normal saline as a treatment option for lipomas. The study will assess whether this technique could serve as a viable alternative to existing treatment options, especially compared to topically applied fat-freezing devices. The Investigators propose that this method may offer a more comfortable nonsurgical option for targeted fat reduction, as the cold temperatures are applied directly to the lipomas.
