Surgery to Improve the Voice
Surgery performed to alter the voice is called phonosurgery. Dr Vokes is experienced in all of the four major types of phonosurgery.
Endoscopic Phonomicrosurgery (Microlaryngoscopy)
Endoscopic phonomicrosurgery (EP) is surgery performed
through a surgical instrument called a laryngoscope that is placed through the mouth to expose the vocal
folds. A microscope is used to visualize the vocal folds. Using this technique,
vocal fold lesions (such as cysts, polyps, papilloma, nodules or cancer) are
removed without making any external incisions.
Laryngeal Framework Surgery
Laryngeal framework surgery (LFS) is surgery performed
through an incision in the skin in the front of the neck over the larynx. It
involves making alterations to the
cartilaginous framework of the larynx.
The most common procedure in this category is a Medialisation
Thyroplasty (also called Type I Thyroplasty), that repositions an
immobile or paralysed vocal fold to improve the voice.
In some cases, a Medialisation Thyroplasty is combined
with an Arytenoid Adduction, a procedure to reposition the
arytenoid cartilage (the back part of the vocal fold) with a suture to further
improve voice quality.
Injection Laryngoplasty
Injection laryngoplasty (IL) is surgery to augment (or
bulk up) the vocal folds with a filler substance. Dr Vokes prefers to use
either Restylane (Hyaluronic Acid) or Restylane Perlane (Hyaluronic Acid) for
tempororay augmentation, or Radiesse (Calcium Hydroxylapatite) for longer
lasting augmentation. This technique is used to treat vocal fold paralysis,
vocal fold paresis (weakness), vocal fold atrophy/bowing (thinning).
In some cases other substances are injected into the
vocal folds, such as Botulinum Toxin (Botox), steroids or antiviral medictions.
Laryngeal Reinnervation
Laryngeal reinnervation (LR) is a technique to improve the voice in people with a
paralysed vocal fold. In this procedure, one of the nerves from the ansa
cervicalis (a collection of nerves that supplies the strap
muscles of the neck) is connected to the main nerve to the larynx (the
recurrent laryngeal nerve). This results in new nerve signals passing into the
vocal fold.
