Description
Voice assessment by endoscopy, also known as laryngoscopy, is a specialized diagnostic procedure used to examine the voice box (larynx) and vocal cords. A thin, flexible endoscope with a camera is passed through the nose or mouth to provide a clear, real-time view of vocal cord structure and function.
This test helps identify the cause of voice changes and guides effective treatment.
Why is This Test Done?
Voice endoscopy is recommended to evaluate:
Persistent hoarseness or voice change
Voice fatigue or strain
Loss of voice (aphonia)
Chronic cough or throat irritation
Suspected vocal cord nodules, polyps, or cysts
Voice issues in professionals (singers, teachers, speakers)
Symptoms of laryngeal infections or tumors
Who Should Get Evaluated?
You should consider voice assessment if:
Hoarseness lasts more than 2–3 weeks
You frequently lose your voice
You have difficulty speaking clearly
You experience throat discomfort while talking
You are a professional voice user
Types of Endoscopic Voice Assessment
1. Flexible Laryngoscopy
A thin, flexible scope is passed through the nose to visualize the vocal cords during breathing and speaking.
2. Rigid Laryngoscopy
A rigid scope is inserted through the mouth for a clearer, magnified view.
3. Video Stroboscopy
A specialized technique that uses flashing light to assess vocal cord vibration in slow motion, helping detect subtle abnormalities.
