Insight into causes, prevention, and when to see an ENT

What Is It?

Hoarseness is a general term that describes abnormal voice changes. When hoarse, the voice may sound breathy, raspy, strained, or there may be changes in volume (loudness) or pitch (how high or low the voice is). The changes in sound are usually due to disorders related to the vocal cords that are the sound producing parts of the voice box (larynx). While breathing, the vocal cords remain apart. When speaking or singing, they come together, and as air leaves the lungs, they vibrate, producing sound. Swelling or lumps on the vocal cords prevent them from coming together properly and changes the way the cords vibrate, which makes a change in the voice, altering quality, volume, and pitch.  

What Are the Causes? Acute Laryngitis: There are many causes of hoarseness. Fortunately, most are not serious and tend to go away in a short period of time. The most common cause is acute laryngitis, which usually occurs due to swelling from a common cold, upper respiratory tract viral infection, or irritation caused by excessive voice use such as screaming at a sporting event or rock concert. Vocal Nodules: More prolonged hoarseness is usually due to using your voice either too much, too loudly, or improperly over extended periods of time. These habits can lead to vocal nodules (singers' nodes), which are callous-like growths, or may lead to polyps of the vocal cords (more extensive swelling). Both of these conditions are benign. Vocal nodules are common in children and adults who raise their voice in work or play.

How Is Hoarseness Evaluated?

An otolaryngologist will obtain a thorough history of the hoarseness and your general health. Your doctor will usually look at the vocal cords with either a mirror placed in the back of your throat, or a very small, lighted flexible tube (fiberoptic scope) may be passed through your nose in order to view your vocal cords. Videotaping the examination or using stroboscopy (slow motion assessment) may also help with the analysis.

These procedures are not uncomfortable and are well tolerated by most patients. In some cases, special tests (known as acoustic analysis) designed to evaluate the voice, may be recommended. These measure voice irregularities, how the voice sounds, airflow, and other characteristics that are helpful in establishing a diagnosis and guiding treatment

When should I see an otolaryngologist (ENT doctor)?

• Hoarseness lasting longer than two weeks especially if you smoke
• Pain not from a cold or flu
• Coughing up blood
• Difficulty swallowing
• Lump in the neck
• Loss or severe change in voice lasting longer than a few days

How Are Vocal Disorders Treated?

The treatment of hoarseness depends on the cause. Most hoarseness can be treated by simply resting the voice or modifying how it is used. The otolaryngologist may make some recommendations about voice use behavior, refer the patient to other voice team members, and in some instances recommend surgery if a lesion, such as a polyp, is identified. Avoidance of smoking or exposure to secondhand smoke (passive smoking) is recommended to all patients. Drinking fluids and possibly using medications to thin the mucus are also helpful.

Specialists in speech/language pathology (voice therapists) are trained to assist patients in behavior modification that may help eliminate some voice disorders. Patients who have developed bad habits, such as smoking or overuse of their voice by yelling and screaming, benefit most from this conservative approach. The speech/language pathologist may teach patients to alter their method of speech production to improve the sound of the voice and to resolve problems, such as vocal nodules. When a patients' problem is specifically related to singing, a singing teacher may help improve the patients' singing techniques.
