Vocal Cord Polyps: Causes, Symptoms, and Treatment

A hoarse, breathy, or rough voice that won't clear up could be a vocal cord polyp — a small, usually benign growth that forms from vocal strain or irritation. Here's how these growths develop and how they're treated.

What Are Vocal Cord Polyps?

The vocal cords (or vocal folds) are two bands of tissue inside the larynx, or voice box, that vibrate together to produce sound when air passes between them. A vocal cord polyp is a small, usually soft and fluid-filled growth that forms on one of the vocal cords, typically as a result of vocal strain, injury, or irritation. Unlike vocal cord nodules, which tend to form as matching pairs on both cords, polyps usually appear as a single growth on one side.

What Causes Vocal Cord Polyps?

• Vocal abuse or overuse — prolonged shouting, singing, or speaking loudly, especially without proper technique
• A single traumatic vocal event, such as one particularly forceful shout or scream
• Chronic irritation from smoking, acid reflux, or persistent throat clearing
• Allergies or chronic coughing that repeatedly strain the vocal cords
• Occupational voice use — teachers, singers, coaches, and call-center workers are especially prone to developing these growths

Signs and Symptoms

• Persistent hoarseness or a rough, raspy voice
• A breathy quality to the voice
• Vocal fatigue — the voice tires quickly with use
• A lower or altered pitch than usual
• A sensation of a lump in the throat or the need to frequently clear the throat
• Occasional voice breaks, particularly at higher pitches

How Vocal Cord Polyps Are Diagnosed and Treated

1. Diagnosis. An ENT specialist examines the vocal cords using a flexible or rigid laryngoscope, sometimes combined with stroboscopy — a special light technique that shows the vocal cords vibrating in slow motion — to assess the polyp's size and impact on vibration.
2. Voice therapy. Many polyps improve with voice therapy alone, working with a speech-language pathologist to correct the vocal habits that caused the growth, alongside resting the voice and treating any underlying reflux or allergies.
3. Surgery, when needed. If the polyp doesn't respond to voice therapy, or is large enough to significantly affect the voice, it can be removed through microlaryngoscopy — a procedure done under general anesthesia using a microscope and tiny instruments passed through the mouth, without any external incision.
4. Precision removal. The surgeon carefully removes just the polyp while preserving as much healthy vocal cord tissue as possible, since even small amounts of scarring can affect voice quality.

Recovery After Surgery

• Voice rest: A period of strict voice rest — often several days to a week — is typically prescribed immediately after surgery to allow the vocal cords to heal without further irritation.
• Gradual return to voice use: Voice therapy usually resumes afterward to help retrain healthy speaking habits and prevent recurrence.
• Full results: It can take several weeks for the voice to reach its final quality as swelling fully resolves.

Risks and Considerations

• Scarring of the vocal cord, which can permanently affect voice quality
• Recurrence if the underlying vocal habits or irritants aren't addressed
• Temporary worsening of the voice immediately after surgery, before healing is complete

The Takeaway

Vocal cord polyps are common, usually benign, and very treatable — often without surgery at all if voice therapy and reduced vocal strain are given a real chance to work. If your voice has been hoarse, rough, or tired for more than a couple of weeks, it's worth seeing an ENT specialist rather than waiting it out, since early treatment tends to give the best results.
