Causes
There are a variety of possible causes including surgical trauma
such as heart, lung and breast surgeries that involve the laryngeal
nerve, or thyroidectomy and endarterectomy. Also cardiovascular disease,
neurological disease, accidental trauma, intubation, or bronoscopy are
also common causes.
Symptoms
These vary depending on the specific paralysis, unilateral (one vocal fold) or bilateral ( both vocal folds).
Clients present with:
- A weak hoarse voice.
- A weak cough.
- Reduced vocal variety.
- Complaint of physical tiredness due to the extra effort required to speak.
Treatment
Work focuses upon trying to reduce the gap between the vocal folds
which is allowing excess air to escape and resulting in a hoarse whisper
type voice quality, along with reducing the physical effort required to
speak.
Posture exercises, compensation exercises aimed at building up the
mobile vocal fold along with specific speech techniques to protect the
mobile cord from over exertion.
