Overview

Vocal cord injection, also known as vocal cord augmentation or vocal fold injection, is a medical procedure used to treat certain voice disorders or vocal cord paralysis. The procedure involves injecting a substance into one or both vocal cords to improve their function and voice quality. The most common materials used for vocal cord injections include:

Hyaluronic Acid

A biocompatible gel that provides temporary augmentation to the vocal cords.

Calcium Hydroxylapatite (CaHA)

Another injectable filler that may offer longer-lasting effects compared to hyaluronic acid.

The injected filler material not only bridges the gap but also enhances the vocal cords’ ability to vibrate and produce sound. It’s important to note that periodic repetitions of this process may be necessary to maintain the desired results.

Fat

In some cases, a patient’s own fat may be harvested from another part of the body and injected into the vocal cords for augmentation.

The procedure is usually performed by an otolaryngologist (ear, nose, and throat specialist) or a laryngologist under local or general anesthesia. During the procedure, the doctor will use a laryngoscope to visualize the vocal cords and carefully inject the chosen material into the targeted areas of the vocal cords.

Vocal cord injection can be beneficial for people with various voice disorders, such as vocal cord paralysis, vocal fold paresis, or vocal cord atrophy. It can help improve voice quality, volume, and overall vocal function. The effects of the injection can be temporary or longer-lasting, depending on the material used.

Like any medical procedure, vocal cord injection carries some risks and potential side effects, such as temporary hoarseness, swelling, or the rare possibility of an allergic reaction to the injected material. It’s essential to discuss the potential risks and benefits with your healthcare provider before deciding to undergo the procedure.
