Understanding Laryngometry: A Diagnostic Tool for Voice Disorders

Laryngometry is a medical procedure that involves measuring the size of the vocal cords. The vocal cords are two small bands of muscle tissue located in the larynx (voice box) that vibrate to produce sound when we speak or sing. Laryngometry is typically performed using a flexible scope called a laryngoscope, which is inserted through the nose or mouth and into the throat to visualize the vocal cords.

During the procedure, the healthcare provider will use the laryngoscope to measure the length and width of the vocal cords, as well as their position and alignment. This information can help diagnose various voice disorders, such as vocal cord paralysis or lesions, and can also be used to monitor the effectiveness of voice therapy or surgical treatments.

There are different types of laryngometry, including:

1. Flexible laryngoscopy: This is the most common type of laryngometry, which uses a flexible scope with a light and camera on the end to visualize the vocal cords.
2. Stroboscopy: This type of laryngometry uses a specialized device that produces a flashing light to examine the movement of the vocal cords during speech or singing.
3. Acoustic laryngometry: This type of laryngometry measures the acoustic properties of the voice, such as pitch and loudness, to assess voice quality and function.
4. Videostroboscopy: This type of laryngometry combines both flexible laryngoscopy and stroboscopy to provide a more detailed examination of the vocal cords and their movement.

Overall, laryngometry is a valuable diagnostic tool for evaluating voice disorders and monitoring the effectiveness of treatment interventions.
