Bilateral Vocal Cord Paralysis is a condition where both vocal cords are unable to move properly. This can cause difficulties in speaking, breathing, and swallowing. In this guide, we’ll break down what bilateral vocal cord paralysis is, its causes, symptoms, diagnostic methods, treatments (including non-pharmacological options and medications), surgeries, preventive measures, and when to seek medical help.
Bilateral Vocal Cord Paralysis occurs when both vocal cords are unable to move due to nerve damage. These vocal cords, located in the larynx (voice box), play a crucial role in speech and breathing. When they are paralyzed, it can lead to various difficulties.
Types:
Bilateral Vocal Cord Paralysis can be categorized based on its severity and underlying causes. The types may include temporary or permanent paralysis, as well as paralysis due to trauma, neurological disorders, or other medical conditions.
Causes:
- Trauma to the neck or chest area
- Surgical complications affecting the vocal cords
- Neurological disorders such as Parkinson’s disease or multiple sclerosis
- Viral infections like herpes zoster or Epstein-Barr virus
- Tumors in the brain or neck region
- Stroke affecting the nerves controlling the vocal cords
- Autoimmune diseases such as myasthenia gravis
- Damage to the recurrent laryngeal nerve during surgery
- Thyroid gland disorders
- Certain medications affecting nerve function
- Idiopathic causes (unknown origin)
- Birth defects affecting the development of the vocal cords
- Chronic inflammation of the larynx
- Vocal cord nodules or polyps
- Exposure to toxins or chemicals
- Gastroesophageal reflux disease (GERD)
- Guillain-Barré syndrome
- Traumatic brain injury
- Radiation therapy to the neck or chest area
- Complications during intubation or prolonged use of a breathing tube
Symptoms:
- Hoarseness or loss of voice
- Difficulty breathing, especially during exertion
- Noisy or labored breathing
- Weak or breathy voice
- Choking or coughing while eating or drinking
- Difficulty swallowing (dysphagia)
- Frequent throat clearing
- Feeling of something stuck in the throat
- Shortness of breath
- Inability to produce loud sounds
- Fatigue from speaking
- Strained voice or effortful speech
- Limited vocal range
- Voice changes with certain positions (e.g., lying down)
- Breathing difficulties worsened by exercise or stress
- Recurrent respiratory infections
- Aspiration pneumonia
- Sleep disturbances due to breathing difficulties
- Voice fatigue after speaking for short periods
- Inability to cough effectively to clear the airway
Diagnostic Tests
(History and Physical Examination): History:
- Detailed medical history including past surgeries, illnesses, and medications
- History of trauma or injury to the neck or chest
- Any recent viral infections or neurological symptoms
- Family history of vocal cord disorders or neurological conditions
- Occupational or environmental exposure to toxins or chemicals
Physical Examination:
- Inspection of the neck and throat for any abnormalities or swelling
- Assessment of vocal cord movement using a laryngoscope or flexible endoscope
- Evaluation of breathing patterns and voice quality
- Palpation of the neck to check for tenderness or masses
- Assessment of swallowing function and cough reflex
Diagnostic Tests:
- Flexible laryngoscopy or videolaryngoscopy to visualize the vocal cords
- Fiberoptic nasopharyngolaryngoscopy for a detailed examination of the upper airway
- Electromyography (EMG) to assess nerve function in the laryngeal muscles
- Imaging tests such as CT scan or MRI to identify structural abnormalities or tumors
- Pulmonary function tests to evaluate respiratory function
- Swallowing studies (videofluoroscopy or fiberoptic endoscopic evaluation) to assess swallowing function
- Blood tests to check for underlying infections, autoimmune diseases, or thyroid disorders
- Nerve conduction studies to assess nerve function in the vocal cords
- Laryngeal electromyography (LEMG) to evaluate the activity of laryngeal muscles
- pH monitoring to assess for gastroesophageal reflux disease (GERD) if suspected
Treatments
(Non-pharmacological):
- Speech therapy to improve vocal cord strength and coordination
- Vocal hygiene techniques to reduce strain on the vocal cords
- Breathing exercises to improve respiratory function
- Swallowing therapy to enhance swallowing coordination and prevent aspiration
- Modified diet texture to facilitate safe swallowing
- Postural adjustments to optimize breathing and voice production
- Voice rest to allow the vocal cords to heal in cases of acute inflammation
- Use of a humidifier to keep the airways moist and reduce irritation
- Avoidance of irritants such as cigarette smoke, air pollution, and strong odors
- Weight management to reduce pressure on the airways and vocal cords
- Elevating the head of the bed during sleep to minimize reflux and aspiration risk
- Inclined exercises to improve cough effectiveness and airway clearance
- Stress management techniques to reduce tension in the neck and throat muscles
- Relaxation exercises such as deep breathing or meditation to promote vocal cord relaxation
- Dietary modifications to prevent exacerbation of reflux or swallowing difficulties
- Use of assistive devices such as voice amplifiers or communication boards
- Postural drainage techniques to facilitate mucus clearance from the airways
- Modification of speaking habits to reduce vocal strain and fatigue
- Avoidance of prolonged or loud speaking in noisy environments
- Collaborative care with otolaryngologists, speech therapists, and respiratory therapists for comprehensive management
Drugs:
- Corticosteroids (oral or injectable) to reduce inflammation and swelling in the airways
- Antibiotics to treat bacterial infections, especially if aspiration pneumonia occurs
- Antacids or proton pump inhibitors to manage gastroesophageal reflux disease (GERD)
- Muscle relaxants to alleviate spasms or tension in the laryngeal muscles
- Botulinum toxin injections to temporarily paralyze overactive laryngeal muscles
- Mucolytics to thin mucus secretions and facilitate clearance from the airways
- Anti-inflammatory medications such as NSAIDs for pain relief and inflammation control
- Antiviral medications for viral infections affecting the vocal cords
- Anticholinergic agents to reduce excessive mucus production and saliva secretion
- Prokinetic agents to improve esophageal motility and reduce reflux episodes
Surgeries:
- Arytenoidectomy to reposition or stabilize the paralyzed vocal cords
- Vocal cord medialization procedures using implants or injectable materials
- Thyroplasty to alter the position of the vocal cord cartilage for improved voice production
- Laryngeal nerve reinnervation surgery to restore nerve function in the vocal cords
- Tracheostomy for severe breathing difficulties requiring long-term airway management
- Cordotomy to selectively damage nerve fibers controlling vocal cord movement
- Partial or total laryngectomy for advanced tumors or irreparable vocal cord paralysis
- Arytenoid adduction to bring the paralyzed vocal cord closer to the midline
- Endoscopic laser surgery to remove tumors or lesions affecting the vocal cords
- Vocal fold augmentation with fat grafts or synthetic materials to improve vocal cord closure
Preventions:
- Avoiding smoking and exposure to secondhand smoke
- Practicing proper vocal hygiene, including staying hydrated and avoiding throat clearing
- Using amplification devices or microphones when speaking in noisy environments
- Seeking prompt treatment for respiratory infections to prevent complications
- Maintaining a healthy weight and regular exercise regimen to reduce the risk of obesity-related complications
- Following proper swallowing techniques to minimize the risk of aspiration
- Using caution during intubation or surgical procedures involving the airway
- Managing underlying medical conditions such as GERD or neurological disorders
- Protecting the neck and chest area from trauma during sports or recreational activities
- Regularly monitoring vocal cord function in individuals at high risk of developing paralysis, such as those with neurological conditions or a history of head and neck surgery
When to See a Doctor:
It’s essential to seek medical attention if you experience any persistent or worsening symptoms related to vocal cord function, breathing, or swallowing. Prompt evaluation by a healthcare professional, preferably an otolaryngologist (ear, nose, and throat specialist), can help determine the underlying cause of your symptoms and guide appropriate treatment. If you notice sudden changes in voice quality, difficulty breathing, or recurrent respiratory infections, don’t hesitate to schedule an appointment with your healthcare provider. Early intervention can improve outcomes and prevent complications associated with bilateral vocal cord paralysis.
