What Is Hoarseness?

Hoarseness refers to any abnormal change in the quality of your voice. This change may result in your voice sounding breathy, raspy, weak, or strained. While occasional hoarseness is common—such as after shouting, singing, or catching a cold—persistent hoarseness lasting more than two weeks may indicate a more serious issue with the vocal cords or larynx (voice box).

For people who rely heavily on their voice, such as teachers, singers, or public speakers, persistent hoarseness can severely impact communication, work, and social interactions. Recognizing when hoarseness becomes abnormal and seeking medical attention early can prevent long-term damage and provide a better chance for successful treatment.

It’s important to understand that hoarseness isn’t a diagnosis on its own—it’s a symptom. Therefore, pinpointing the underlying cause of hoarseness is crucial in choosing the right course of treatment. It could be related to vocal cord misuse, infection, or even more serious conditions like tumors or neurological issues.

Understanding the Anatomy of the Vocal Cords

To understand why hoarseness occurs, it helps to know the basic anatomy and function of your vocal cords. The vocal cords are two flexible bands of muscle tissue that sit in the larynx, which is located in your throat. These bands vibrate when air from the lungs passes through them, producing sound. The resulting sound is shaped by the mouth, tongue, and lips, allowing for speech and singing.

In a healthy voice, the vocal cords should close tightly and vibrate smoothly. When they become swollen, inflamed, or injured, they may not close completely, which leads to a weak, raspy, or breathy voice. The vocal cords play a vital role in speaking, but they also protect the airway during swallowing, ensuring that food or liquids don’t enter the lungs.

Maintaining vocal health is important not only for communication but also for the protection of your airway. In addition to speaking and singing, vocal cords play a crucial role in protecting the lungs by preventing aspiration, the inhalation of food or liquid into the lungs.

Common Causes of Persistent Hoarseness

Several factors can contribute to persistent hoarseness. Some are temporary, while others require medical intervention. Here are the most common causes:

1. Vocal Cord Nodules and Polyps
   Vocal cord nodules are small, benign (non-cancerous) growths that form as a result of vocal strain or overuse. People who regularly use their voice in loud environments, such as teachers or singers, are at a higher risk. Nodules develop over time, causing the vocal cords to stiffen and not vibrate smoothly, leading to a hoarse voice. Polyps, while similar to nodules, can result from a single episode of intense vocal strain or injury and are often larger.

   Case Study: A professional singer who frequently performs on stage might experience vocal cord nodules as a result of prolonged high-pitch singing. The strain on their vocal cords leads to changes in their voice quality, making it sound hoarse or raspy. Rest and voice therapy can help resolve the issue, but in some cases, surgical intervention may be necessary to remove the growths.

2. Vocal Cord Paralysis or Paresis
   Vocal cord paralysis occurs when one or both vocal cords become paralyzed and cannot move as they should. This may happen due to nerve damage caused by surgery, injury, infections, or neurological conditions. Paralysis often results in a weak or breathy voice, and may also cause difficulty swallowing and even choking. Paresis, a partial paralysis, involves reduced movement in the vocal cords, leading to similar symptoms but often in a less severe form.

   Example: After a thyroidectomy, a patient might develop vocal cord paralysis due to damage to the nerve that controls vocal cord movement. This results in difficulty speaking, especially in higher pitches, and may require voice therapy or, in severe cases, surgery to reposition the vocal cord.

3. Laryngitis and Chronic Inflammation
   Laryngitis is an inflammation of the vocal cords, often due to viral infections, overuse of the voice, or irritants like smoking. While acute laryngitis typically resolves in a few days, chronic laryngitis can last for months and significantly affect voice quality. This long-term inflammation is often associated with ongoing exposure to irritants or conditions like gastroesophageal reflux disease (GERD), which causes stomach acid to irritate the vocal cords.

   Chronic laryngitis is common among people who frequently use their voices for work, such as teachers or public speakers. Voice strain from excessive talking or shouting can inflame the vocal cords, leading to persistent hoarseness.

4. Vocal Cord Dysfunction
   Vocal cord dysfunction (VCD) occurs when the vocal cords do not move normally, leading to difficulty breathing and speaking. This condition is often confused with asthma or chronic respiratory issues because its symptoms—such as wheezing, shortness of breath, and hoarseness—are similar. VCD can be triggered by stress, environmental irritants, or physical exertion.

   Case Study: A professional athlete who experiences difficulty breathing and hoarseness during intense physical activity might be suffering from vocal cord dysfunction. This can be diagnosed through laryngoscopy and treated with voice therapy to help control the abnormal movements of the vocal cords.

5. Other Causes
   Other potential causes of persistent hoarseness include conditions like gastroesophageal reflux disease (GERD), smoking, allergies, and infections. In some rare cases, persistent hoarseness can signal the presence of cancer in the larynx, particularly in individuals who smoke or are over 40 years old. Persistent hoarseness in these individuals warrants further investigation to rule out malignancy.

   Example: A long-term smoker who develops hoarseness along with a lump in the throat and difficulty swallowing may need to be evaluated for laryngeal cancer. Early diagnosis significantly improves the chances of successful treatment.

When Should You Seek Help?

Hoarseness is a common and often temporary condition, but when it becomes persistent, it’s important to seek professional medical help. Here are some key signs that indicate you should see a healthcare provider:

• Duration: If hoarseness lasts for more than two weeks, it may indicate an underlying problem that needs to be evaluated by a doctor.

• Accompanying Symptoms: Hoarseness combined with difficulty swallowing, a lump in the throat, unexplained weight loss, or breathing difficulties requires urgent medical attention.

• Professional Voice Users: If you rely on your voice for work, such as a teacher, singer, or public speaker, even mild hoarseness should not be ignored. Early intervention can prevent long-term damage.

The Diagnostic Process for Vocal Cord Problems

If hoarseness persists, a thorough diagnostic workup is necessary. At Sangdo Woori Internal Medicine, led by Dr. Yoo Du-yeol, experts use a combination of medical history, physical examination, and advanced diagnostic tools to identify the cause of persistent hoarseness.

• Laryngoscopy
  Laryngoscopy involves using a flexible tube with a camera (laryngoscope) to examine the vocal cords and larynx. This procedure helps identify abnormalities such as polyps, nodules, inflammation, or tumors. It is typically performed in the office and provides real-time images of the vocal cords.

• Stroboscopy
  Stroboscopy takes laryngoscopy a step further by using a strobe light to visualize the vibrations of the vocal cords during speech. This technique helps detect subtle issues, such as incomplete closure of the vocal cords, which may not be visible with standard laryngoscopy. Stroboscopy is especially useful in diagnosing vocal fold lesions or other subtle abnormalities.

• Additional Tests
  If further evaluation is needed, additional tests may be performed, including CT scans or MRIs to assess for structural issues or tumors, and blood tests to check for infections or other systemic conditions. Voice assessments by speech-language pathologists are also important to evaluate the functional impact of the vocal cord issues.

Treatment for Persistent Hoarseness

Treatment for hoarseness depends on the underlying cause and severity of the condition. At Sangdo Woori Internal Medicine, Dr. Yoo Du-yeol and his team offer a range of treatment options tailored to each patient’s needs.

1. Voice Rest and Therapy
   For conditions like vocal cord nodules or inflammation, voice rest is often the first line of treatment. However, voice therapy with a speech-language pathologist is often necessary to prevent further strain on the vocal cords and ensure proper healing. Voice therapy teaches patients proper vocal techniques and helps retrain muscles to reduce strain.

2. Medical Treatments
   If inflammation is the cause, medications like corticosteroids can be prescribed to reduce swelling. For patients with acid reflux-related hoarseness, proton pump inhibitors and lifestyle changes (such as dietary modifications) are recommended to prevent further irritation of the vocal cords.

3. Surgical Interventions
   Surgery may be necessary if conservative treatments fail. This is often the case with persistent nodules, polyps, or lesions that don’t respond to voice therapy or rest. Surgical procedures may also be required for vocal cord paralysis, where a procedure can reposition or augment the affected vocal cord to improve voice quality.

Voice Therapy and Rehabilitation

Voice therapy is an essential component of treating many vocal cord issues. For example, a teacher who develops hoarseness due to vocal strain might benefit from personalized voice therapy that includes exercises to strengthen the vocal cords and improve vocal technique. These therapies can significantly improve voice clarity, endurance, and confidence, enabling individuals to return to their daily activities with restored vocal health.

Why Early Intervention Matters

Ignoring hoarseness can lead to serious complications, including permanent vocal damage and difficulty swallowing. Early diagnosis and treatment can prevent long-term damage and improve recovery. At Sangdo Woori Internal Medicine, a multidisciplinary approach ensures that patients receive the most effective care, combining advanced diagnostic techniques with expert medical management.

Preventing Vocal Cord Problems

Prevention is key to maintaining healthy vocal cords. Here are some helpful tips to protect your voice:

• Practice Proper Vocal Hygiene: Avoid excessive yelling or speaking loudly for extended periods.

• Stay Hydrated: Drink plenty of water to keep the vocal cords lubricated.

• Avoid Irritants: Smoking and exposure to allergens can irritate the vocal cords, so it’s important to avoid these triggers.

• Take Regular Voice Breaks: If your work involves frequent vocal use, take breaks to rest your voice.
