Can you be born with aphonia?

Aphonia is the most severe of speech disorders; complete loss of the voice. Can someone be born with this disorder?

It happens.  (+ info)

what kind of injuries cause Aphonia?

one of my friends is a mute and i was wondering how he got it

Aphonia is the medical term for the inability to speak. A primary cause of aphonia is atrophy in the nerves that supply nearly all the muscles in the larynx. A second cause of this inability to produce vocal sounds may be a consequence of the surgical removal of the larynx—necessary as a treatment for cancer of the neck, for example

A chemotherapy drug –vincristine—used in the treatment of such cancers
as non- Hodgekin’s lymphoma, breast, lung and leukemia has the nasty side
effect of causing damage to the laryngeal nerves that supply the muscles in the larynx.

Pages 738-739)
www.nlm.nih.gov/medlineplus/druginfo/medmaster/a682822.html The FDA appears to have
given permission to use this drug for several conditions listed here.

The drug is administered through a vein. As a consequence many times medical personnel must monitor a patient treated with this drug carefully because should the drug “leak” from, or not get into the vein in the first place, all surrounding tissue at the site of the injection may be compromised. That is just ONE of the side effects of this drug. See the web site above for more information.

If this mute is a classmate, depending on your age, I would think that at some point your friend has undergone chemo for leukemia or developed aphonia as a consequence of treatment with Vincristine. for some other condition  (+ info)

When someone losses their voice but there is not structural damage to the larynx or neuro basis it is called?

Im not sure if it is Aphonia or Dysphonia.

Definitions of both:
Dysphonia is the medical term for disorders of the voice: an impairment in the ability to produce voice sounds using the vocal organs (it is distinct from dysarthria which means disorders of speech, that is, an impairment in the ability to produce spoken words). Thus, dysphonia is a phonation (to vocalize) disorder. The dysphonic voice can be hoarse or weak, or excessively breathy, harsh, or rough, but some kind of phonation is still possible (contrasted with the more severe aphonia where phonation is impossible).
Aphonia is the medical term for the inability to speak. It is considered more severe than dysphonia. A primary cause of aphonia is bilateral disruption of the recurrent laryngeal nerve, which supplies nearly all the muscles in the larynx. Damage to the nerve may be the result of surgery (e.g., thyroidectomy) or a tumor. Aphonia means "no voice." In other words, a person with this disorder has "lost" his/her voice.

Hope this helps!  (+ info)
