Vocal cord paralysis can be treated through voice therapy, vocal cord injections, and surgical procedures including thyroplasty and arytenoid adduction. These treatments help restore voice quality and improve breathing function when nerve damage prevents normal vocal cord movement.
This condition affects approximately 1 in 1,000 people, causing significant voice changes and potential breathing difficulties. The nerve signals controlling vocal cord movement become interrupted, preventing normal vocal cord function during speaking and breathing.

What Causes Vocal Cord Paralysis?
Vocal cord paralysis results from damage to the recurrent laryngeal nerve, which controls vocal cord movement. Common causes include surgical complications, viral infections, cancer, and neurological conditions that affect nerve function.
Thyroid surgery represents the most frequent cause of vocal cord paralysis, with studies showing that 2-5% of thyroid operations result in temporary or permanent vocal cord paralysis. Heart surgery and other neck procedures also pose risks to these delicate nerves.
Viral infections can cause temporary vocal cord paralysis that may resolve spontaneously over several months. However, in some cases, the damage becomes permanent, requiring intervention to restore voice function.
How Does Vocal Cord Paralysis Affect Voice Quality?
Vocal cord paralysis significantly impacts voice quality by preventing complete vocal cord closure during speaking. This incomplete closure allows air to escape, creating breathiness, weakness, and reduced vocal loudness.
The paralysed vocal cord cannot move to meet its partner, resulting in a gap that affects sound production. Patients often describe their voice as weak, breathy, or requiring excessive effort to produce adequate volume.
Swallowing difficulties may accompany voice changes, as the same muscles involved in vocal cord closure help protect the airway during swallowing. This can lead to coughing, choking, or aspiration of food and liquids.
Can Vocal Cord Paralysis Improve Without Treatment?
Yes, vocal cord paralysis can improve spontaneously, particularly when caused by viral infections or surgical swelling. Recovery typically occurs within 6-12 months, with gradual return of nerve function and vocal cord movement.
However, many cases require active treatment to achieve optimal voice restoration. Even when some natural recovery occurs, residual weakness or incomplete closure may persist, benefiting from therapeutic intervention.
The likelihood of spontaneous recovery depends on the underlying cause and extent of nerve damage. Cases involving complete nerve severing are unlikely to recover without surgical intervention.
What Treatment Options Are Available For Vocal Cord Paralysis?
Treatment options range from voice therapy to surgical intervention, depending on the severity and duration of paralysis. Voice therapy teaches compensation techniques that help the functioning vocal cord work more effectively.
Vocal cord injection involves placing temporary or permanent materials into the paralysed vocal cord to improve closure. These injections can significantly improve voice quality and reduce breathiness whilst patients await potential recovery.
Surgical options include vocal cord repositioning procedures that permanently adjust the paralysed cord’s position. These operations aim to improve vocal cord closure and restore more normal voice production.
How Effective is Voice Therapy for Vocal Cord Paralysis?
Voice therapy is highly effective for teaching compensation strategies that maximise remaining vocal function. Therapists help patients develop techniques to improve vocal cord closure using the functioning cord more efficiently.
Techniques include breath support exercises, vocal cord adduction exercises, and strategies for improving vocal loudness and clarity. Many patients achieve significant voice improvement through therapy alone, particularly in cases of partial paralysis.
Research shows that 70-80% of patients experience meaningful voice improvement with dedicated voice therapy. The therapy is most effective when combined with other treatments such as vocal cord injection or surgery.
What Surgical Options Exist for Vocal Cord Paralysis?
Surgical options include vocal cord injection, thyroplasty, and arytenoid adduction procedures. Each approach aims to improve vocal cord closure and restore more normal voice production through different mechanisms.
Vocal cord injection involves placing materials such as hyaluronic acid or calcium hydroxyapatite into the paralysed cord to increase its bulk and improve closure. This procedure can be performed under local anaesthetic with immediate voice improvement.
Thyroplasty involves placing an implant that pushes the paralysed vocal cord towards the midline, improving closure with the functioning cord. This procedure provides predictable, long-term voice improvement for appropriate candidates.
What Can Patients Expect During Recovery From Vocal Cord Paralysis?
Recovery varies significantly depending on the treatment approach and individual factors. Voice therapy typically shows gradual improvement over several weeks to months, with patients learning to use their voice more efficiently.
Vocal cord injection provides immediate voice improvement, though the effects may be temporary with certain materials. Patients typically notice reduced breathiness and improved vocal strength within hours of the procedure.
Surgical procedures require several weeks of healing before optimal voice improvement becomes apparent. Most patients experience progressive voice improvement over 3-6 months following surgery.
How Can Patients Cope With Vocal Cord Paralysis?
Coping strategies include voice conservation techniques, communication aids, and lifestyle modifications that accommodate voice limitations. Patients learn to use their voice strategically, preserving vocal energy for important communications.
Environmental modifications such as reducing background noise and facing conversation partners help maximise communication effectiveness. Many patients benefit from amplification devices that reduce the effort required for voice projection.
Support groups and counselling help patients adjust to voice changes and maintain social connections. Many individuals find that connecting with others who have experienced similar challenges provides valuable emotional support and practical advice.
If you’re experiencing symptoms of vocal cord paralysis, don’t wait for the condition to worsen. Early intervention often leads to better outcomes and faster recovery. Contact Nick Hamilton today to discuss your treatment options and begin your journey towards voice restoration.
