Spasmodic Dysphonia and Botox Application to the Vocal Cord

Spasmodic Dysphonia and Botox Application to the Vocal Cord

Dysphonia is a functional voice disorder caused by a vibration disorder in the vocal cords, which manifests itself as hoarseness or a thin or thick irregular voice.

It is also used as a general term for all voice disorders. The leading cause of dysphonia is misuse and strain of the vocal cords. If misuse continues, tissue deterioration such as nodules, polyps, cysts, cancer or paralysis can be seen in the vocal cords.

Spasmodic Dysphonia and Botox Application to the Vocal Cord

Spasmodic Dysphonia is when functional voice disorder is seen suddenly with sudden contractions (spasms) during speech. The most important feature is that it is a chronic voice disorder. These spasms last for a long time and recur frequently.

During spasmodic dysphonia, the vocal cords do not move as they normally should. They suddenly become tense and contract. With this abnormal behavior of the vocal cords, which perform the function of producing sound, the voice suddenly becomes hoarse or hoarse, shaky, intermittent. During the contractions, the involuntary functions of the vocal cords and larynx are normal, only the voice is affected. The contractions may recur several times during the day.Spasmodic Dysphonia is a purely organic disorder, although it has similarities with psychiatric disorders. It is often seen in the 30-50 age range and starts with infrequent voice production difficulties and becomes a more frequent and challenging problem over time.

It is not known exactly what causes Spasmodic Dysphonia. Therefore, it is also difficult to diagnose. In order to examine the vocal cords and their functions, brain and nerve functions, as well as voice production and use, diagnosis can be made with a simultaneous examination by an ear-nose-throat specialist, neurologist, speech therapist and speech therapist.

Although methods such as drug therapy, voice therapy, thyroplasty, muscle electrical stimulation (stimulation) are used from time to time in Spasmodic Dysphonia, there is no generally accepted treatment that provides definitive improvement. Today, Botox (Botulinum Toxin) injection can be applied to one or both vocal cords to reduce the tension of the vocal cords and minimize the complaints of contraction due to weakened vocal cords. This treatment method has become the most preferred method compared to other methods.

How to Apply Botox for Spasmodic Dysphonia?

Botox (Botulinum Toxin) is derived from the Clostridium Botulinum bacteria found in nature. It is actually a very toxic toxin. However, it can be given to humans in extremely small concentrations.

Muscles contract when a chemical called acetylcholine, released by nerves, attaches to receptors on muscle cells. Botox prevents the release of acetylcholine by the nerves, weakening the muscles and preventing contraction.

In patients with Spasmodic Dysphonia, Botox is usually injected into the vocal cords by entering the neck area with a small needle. Depending on the patient's condition and request, it can also be injected into the vocal cords from the inner part of the throat by entering the mouth area with a long needle under short-term general anesthesia. In this way, the vocal cords relax and the contractions weaken.

In light of the diagnosis, it can be applied to one or both vocal cords. There is no risk of poisoning, it does not spread to the body. The amount of botox used in aesthetic operations is usually 40-80 doses. The dose used for Spasmodic Dysphonia is mostly 1-2 doses, with a maximum of 15 doses. The effect of Botox can be seen within 24-72 hours. This period can rarely last up to 5 days. After Botox takes effect, the patient usually goes through three stages:

  • Breath Phase: It is the stage where the effect of Botox is the highest and the vocal cord muscles are the weakest. The sound produced is weak and shrill. Temporary difficulty in swallowing and swallowing may be experienced. It may last for a few days or a few weeks.
  • Normal Phase: The effect of Botox is normal and the vocal cord muscles are slightly strengthened but too loose to contract. The sound and breathing are normal. It may take a few weeks or a few months.
  • Regeneration Phase: The effect of the Botox diminishes and disappears and the vocal cord muscles are strengthened again and contractions can occur again. The voice and breathing worsen. The need for re-injection appears.

In my first meeting with Mr. Elad, I trusted him immediately. He is both a warm-blooded, friendly doctor and explains everything in detail and honestly. I am in the 1st month of my surgery. I had a bruise-free, painless process. I also already love the shape of my nose :) If you want a natural nose that is compatible with your face, Mr. Elad is the right choice. His team and himself are very interested. They do not think that the surgery is over. I can recommend my doctor with peace of mind. I thank him and his team endlessly.

Elif Demirtaş Kanburoğlu

When you go to him for the first interview, you will already take the day for surgery and leave :) a doctor who is so sweet and explains everything to the finest detail. I saw 1 bad comment, I think anyone who knows the deliberate Elad knows that he will not treat the patient with such a style.
