Inside ExcelENT’s Speech Lab: Video Laryngeal Stroboscopy

Most people go their entire lives without seeing the two small folds of tissue behind every word they speak. Then a hoarse voice lingers for weeks, a cough refuses to quit, or a singing voice starts cracking on notes that used to come easily. Video laryngeal stroboscopy is the exam that finally puts those vocal cords on screen, revealing what the ear alone can’t catch.

This provider spotlight goes inside ExcelENT’s speech lab with Janice Sullivan-Stoll, MM, MS, CCC-SLP, the speech pathologist who performs these exams. Her path started on an opera stage, and that training shapes how she hears every voice she evaluates. Here’s what she looks for, what patients can expect, and why most voice problems are far from permanent.

From Opera Training to Voice Diagnosis

Janice began as a music major studying opera, which sparked her fascination with vocal cords. She later returned to school for speech pathology to work with singers and others facing vocal problems.

That training gave her a finely tuned ear for subtle shifts in voice quality. Figuring out how someone produces a sound, and how to modify it, is the heart of voice therapy.

What Happens During a Video Laryngeal Stroboscopy

After a thorough health history, Janice guides a flexible scope through one side of the nose. Patients sniff, hold an “ee” sound, and give a quick sample of their speaking voice, plus their singing voice if they’re a singer. The exam takes about two to three minutes and is recorded, so Janice can review the footage with each patient afterward.

The camera’s chip sits at the very tip of the scope, producing crisp, close-up images of the vocal cords. A strobe light then creates a slow-motion view of vibrations that happen far too fast for the eye to follow. 

And the reactions? Plenty of patients say their vocal cords look gross, and the polite ones compare them to aliens. Most end up fascinated by how their voices actually work.

What a Vocal Cord Evaluation Reveals

An accurate voice disorder diagnosis depends on knowing what to look for. During each vocal cord evaluation, Janice checks a few key details:

• Masses or lesions: Any abnormal growth on or near the vocal cords is noted first.
• Symmetry: Both cords should open and close evenly, and uneven movement can point to a laryngeal nerve problem.
• Color: Healthy vocal cords look pearly white, so redness or irritation tells a story.
• Edges: Smooth, straight edges are healthy, and a one-sided lesion reads differently than a matching pair.
• Vibration: If the tissue looks stiff or keeps moving over a lesion, that helps identify the lesion type.

The American Speech-Language-Hearing Association compares nodules to calluses and polyps to blisters, and stroboscopy gives the care team a clear view of both. When Janice spots something abnormal, she shares the images with Dr. Davis or Dr. Walz, and together they map out the next steps

Who Ends Up in the Speech Lab?

• Young singers: Teenage vocalists with vocal cord nodules tend to arrive in waves.
• Teachers: Music teachers and those who teach young children often use their voices for classroom management without amplification, which can lead to swelling or nodules.
• People with a lingering cough: A chronic cough lasting longer than six to eight weeks often has several causes, and behavioral cough suppression therapy can calm an overly sensitive larynx. 
• Frequent throat clearers: Chronic throat clearing can stem from postnasal drip, sinus issues, or reflux, so the larynx gets a close look too.

No matter which provider a patient sees first, a lingering cough or constant throat clearing usually leads to a stroboscopy, since something on or near the vocal cords could be the trigger. As Janice puts it, “All paths lead to visualization.”

Nodules and Polyps Aren’t Always Permanent

One of the biggest misconceptions Janice hears is that nodules, polyps, and other benign lesions are permanent. Voice therapy is often the first line of treatment, and those growths can resolve.

The National Institute on Deafness and Other Communication Disorders lists voice rest, voice therapy, and surgery as the most common treatments. When removal is necessary, voice therapy before and after surgery gives the vocal cords the best chance at a strong recovery. These vocal hygiene tips are a good place to start for anyone who talks, teaches, or sings for a living.

Seeing Your Voice Changes Everything

Hoarseness, vocal strain, and a stubborn cough often trace back to the vocal cords. Video laryngeal stroboscopy brings them into view in minutes, and for many patients, that clear picture leads to therapy that resolves the problem long before surgery enters the conversation.

In Birmingham, that picture comes from top-tier technology in the hands of a speech pathologist with an opera singer’s ear. ExcelENT’s distal-chip stroboscopy system captures some of the sharpest vocal cord images available, and outside of UAB, it’s the only system of its kind in the area.
