When lasting hoarseness should be checked, how the vocal cords are examined, common benign causes, voice therapy, and when vocal cord microsurgery is considered.

In short

Hoarseness that has not cleared up or improved within about four weeks should be checked by an ENT specialist who looks at the vocal cords, and sooner if you smoke, cough up blood, have difficulty swallowing or breathing, or notice a lump in your neck. The cause is often benign, such as nodules, a polyp, a cyst or strain on the voice; voice therapy usually comes first, and microsurgery is considered for a lesion that does not settle or needs a diagnosis.

Hoarseness means a voice that sounds rough, breathy or strained, is weaker than usual, or tires quickly. Most episodes come with a cold or heavy voice use and settle by themselves. When hoarseness lasts, the cause is still often benign, but the only way to find it is to look at the [vocal cords](https://www.drcenkteker.com/en/procedures/vocal-cord-microsurgery/). This article is about adults; your own plan comes from the specialist who examines you.

## When hoarseness should be checked

A clinical guideline from the American Academy of Otolaryngology–Head and Neck Surgery Foundation recommends an examination of the larynx, called laryngoscopy, when hoarseness has not cleared up or improved within four weeks; some advice for family doctors uses three weeks. The same guideline advises examining the larynx sooner, whatever the duration, when a serious cause is suspected.

Have it checked without waiting four weeks if the hoarseness comes with any of these:

- you smoke or have smoked
- difficulty or pain when swallowing
- coughing up blood
- a lump in the neck
- noisy breathing or difficulty breathing
- it began after an operation on the neck or chest, or after a breathing tube was used during anaesthesia
- your work depends on your voice

These signs do not by themselves mean that something serious is present; they mean the larynx should be examined promptly rather than watched. Sudden or severe difficulty breathing is an emergency: call 112.

Because treatment depends on the cause, the guideline also advises against routine antibiotics, against steroid medicines before the larynx has been seen, and against reflux medicines for hoarseness alone without an examination. A medicine taken without a diagnosis may not help and can delay finding the cause.

## How the vocal cords are examined

After questions about your voice, smoking, reflux symptoms such as heartburn and any recent operation, and a check of your neck, laryngoscopy is done in the clinic while you are awake. Either a thin, flexible camera is passed through the nose, usually after a numbing spray, or a rigid telescope is held at the back of the mouth while you say a long “eee”. It takes a few minutes and may make you want to sneeze or gag briefly.

Stroboscopy adds a light that flashes in time with your voice, so the vibration of the vocal cords can be watched as if in slow motion. It shows changes along the vibrating edge that ordinary light can miss.

## Common causes of lasting hoarseness

Nodules are small, firm swellings that usually form in pairs, opposite each other, in the middle of both vocal cords. They develop with repeated strain, such as talking loudly or for hours, and are common in teachers, singers and others who use their voice a great deal.

Polyps are softer swellings, usually on one vocal cord, linked to voice strain and to smoking. Cysts are small sacs under the lining of a vocal cord, usually on one side. Both stop the vocal cords from closing and vibrating evenly.

Reflux, where stomach contents rise into the throat, can irritate the larynx. Hoarseness can also come from the way the voice is used, with no lesion at all: the muscles around the larynx work harder than they need to, which is called muscle tension dysphonia.

Less common causes include a vocal cord that moves weakly or not at all, age-related thinning of the vocal cords, and a growth that needs a sample taken to rule out cancer. Telling these apart is what the examination is for.

## Voice therapy usually comes first

Voice therapy is given by a speech and language therapist who works with voice. It changes how you produce your voice, including breathing, effort, pitch and loudness, and the habits that strain the vocal cords. The guideline describes it as the first treatment for lesions such as nodules, polyps and cysts, once the larynx has been examined.

A course usually means one or two sessions a week for four to eight weeks, with practice at home in between. For nodules, voice therapy is the usual first treatment, and surgery is considered only if symptoms continue despite it.

Everyday care supports any treatment: drinking enough water, not smoking, not shouting or talking over loud noise, resting the voice when it feels tired, and treating reflux when it has been found.

## When microsurgery is considered

The guideline lists surgery as an option for benign lesions that still cause symptoms despite voice therapy and other non-surgical treatment, and for lesions that may not be benign. In practice this usually means a polyp or cyst that has not improved, nodules that persist despite therapy, or a lesion that needs to be removed or sampled for laboratory examination. Whether surgery makes sense for you is decided after the examination, together with you.

The operation, called microlaryngoscopy, is done under general anaesthetic. A metal tube, the laryngoscope, is passed through the mouth to bring the vocal cords into view, and the surgeon works through it with a microscope and fine instruments, so there is no cut on the neck. A guard protects the teeth. You can often go home a few hours later, although some people stay overnight.

Surgery removes the lesion but not the voice habits that may have caused it, so voice therapy often continues afterwards; the guideline counts it as part of surgical treatment.

## What voice rest after surgery means

Complete voice rest means making no sound with the voice at all: no talking, whispering or singing, and as little throat clearing and coughing as you can manage, so you communicate by writing. Relative voice rest means speaking only when needed, briefly and quietly.

Which kind, and for how long, depends on what was removed. A survey of ENT surgeons in the UK found wide differences in the advice they gave and linked this to a lack of firm evidence. Periods from a few days to about a week are common; follow the plan your own surgeon gives you.

The voice is then brought back into use gradually, often with a voice therapist. Drink plenty of water and speak quietly in the first days. While the lining heals, the voice can sound worse for a while, especially after a biopsy.

## Risks of vocal cord surgery

A sore throat, sometimes with a stiff neck, is common for a day or two, as are small cuts or bruises on the lips, gums or tongue, which heal quickly. Spitting a little blood usually settles within a day. The laryngoscope can chip or damage teeth despite the guard, especially crowns, bridges and weak teeth, so tell your surgeon about them beforehand.

Less often, the airway swells and needs medicine or an overnight stay in hospital. A cough when eating or drinking afterwards should be reported, as food or drink may be going the wrong way. General anaesthesia has its own rare risks, which are discussed with you beforehand.

The voice can stay hoarse or different for some time while the vocal cord heals. In some people it improves less than hoped, for example when scar tissue forms, and nodules and polyps can come back if the strain that caused them continues. Results differ from person to person.

Questions about your own voice, what the examination shows and which treatment fits you are answered at a consultation, once the vocal cords have been seen.
