Paralyzed Vocal Cords and Nodule Formation

Paralyzed vocal cords are the one which does not move at all which results in a gap between the vocal cords. When an affected person attempts to talk, this gap results in air escape which causes a “breathy” sounding voice. Read on to know more about paralyzed vocal cords and nodule formation.

Vocal Cords – What are they?
The vocal folds or cords are two tiny muscles which are located within the voice box (larynx). This is responsible for producing voice. The vocal cords are found near thyroid cartilage or Adam’s apple in the neck. These are very small measuring about 11mm in length for females and 18mm in length for males.

How is Speech/Voice Produced?
Most frequently, these vocal cords lie apart from each other. They form a small “V” shaped opening. They come close together and make sound by vibrating during speech. Movement of the tongue and speech changes this sound to produce specific speech sounds.Paralyzed Vocal Cords and Nodule Formation

Vocal Cord Paralysis – What is it?
Each one of the vocal cords are moved and controlled by a nerve known as the recurrent laryngeal nerve. This nerve lies one on each side of the vocal cords. When the nerve fails to function properly, the vocal cord attached to it cannot move. This impaired condition is known as paralyzed vocal cords. This condition can result in either speech or breathing problems. Damage to any one of the vocal cords can lead to a “breathy” voice production, although very rarely any breathing problems occurs. Damage to both the vocal cords can cause severe noisy breathing known as stridor, although the voice remains strong.

Vocal Cord Nodules – What are Nodules?
These nodules on the vocal cords are callous-like bumps. These bumps can form on either one or both of the vocal cords. Also, the nodules are present on the front 1/3 of the cords. They have a wide range of size starting from a pinhead to split pea. In normal speech, your vocal cords should firmly press together. But if nodules are present, then the vocal cords cannot close completely. Hence, extra air escapes and your voice sounds breathy and hoarse as a result.
