A report on Larynx and Hoarse voice

Anatomy of the larynx, anterolateral view
The vocal folds (or vocal cords) in the larynx vibrate to produce sound. When this process is disturbed hoarseness may ensue.

The assessment and diagnosis of dysphonia is done by a multidisciplinary team, and involves the use of a variety of subjective and objective measures, which look at both the quality of the voice as well as the physical state of the larynx.

- Hoarse voice

Injury to one of the recurrent laryngeal nerves produces hoarseness, if both are damaged the voice may or may not be preserved, but breathing becomes difficult.

Vocal cords

In humans, vocal cords, also known as vocal folds or voice reeds, are folds of throat tissues that are key in creating sounds through vocalization.

They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.

Patients suffering from vocal fold scar complain about increased phonatory effort, vocal fatigue, breathlessness, and dysphonia.

Vocal cord nodule

Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds.

Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds.

As such, the major perceptual signs of vocal fold nodules include vocal hoarseness and breathiness.

Other common symptoms include vocal fatigue, soreness or pain lateral to the larynx, and reduced frequency and intensity range.

Laryngitis

Laryngitis is inflammation of the larynx (voice box).

Symptoms often include a hoarse voice and may include fever, cough, pain in the front of the neck, and trouble swallowing.

Laryngopharyngeal reflux (LPR) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx.

LPR causes respiratory symptoms such as cough and wheezing and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia.

vocal cord positions regarding paralyses

Vocal cord paresis

Injury to one or both recurrent laryngeal nerves , which control all intrinsic muscles of the larynx except for the cricothyroid muscle.

vocal cord positions regarding paralyses

A unilateral injury of the nerve typically results in hoarseness caused by a reduced mobility of one of the vocal folds.

Though voice qualities may appear normal in some cases of vocal fold paresis or paralysis, mild differences in tension between the two vocal folds of the larynx can result in changes of voice pitch, intensity and reduced vocal stamina.
