Nanofat injection is a next-generation vocal fold treatment that uses highly refined fat from your own body — processed to retain powerful healing factors while removing the bulkiness of traditional fat. It’s used to treat vocal fold atrophy and paresis (weakness), especially in patients seeking natural, regenerative options to restore fullness and elasticity to the voice.

The procedure starts with a small amount of fat gently harvested from an area like the abdomen or thigh — often using a mini-liposuction technique. The fat is then emulsified into a smooth, injectable form rich in stem cells and regenerative proteins. In the same visit (or occasionally a follow-up), the nanofat is injected into the vocal folds using a flexible laryngoscope and fine needle. The process takes about 60–90 minutes total. Most patients tolerate it well, with only minor soreness at the donor site and a full sensation in the throat for a day or two. Voice rest is usually recommended for 2–3 days. Results are often longer-lasting than those of synthetic fillers, and many patients notice gradual improvement in strength, range, and clarity over several weeks. This procedure is low-risk, with the added benefit of using your own tissue for natural, biocompatible healing.
