Laryngoscopy (/ ˌ l ær ɪ ŋ ˈ ɡ ɒ s k ə p i /) is endoscopy of the larynx, a part of the throat. It is a medical procedure that is used to obtain a view, for example, of the vocal folds and the glottis .
MTD is a unifying diagnosis for a previously poorly categorized disease process. It allows for the diagnosis of dysphonia caused by many different etiologies and can be confirmed by history, physical exam, laryngoscopy and videostroboscopy, a technique that allows for the direct visualization of the larynx, vocal cords, and vocal cord motion.

Flexible Endoscopic Evaluation of Swallowing with Sensory Testing (FEESST), is essentially a Flexible Endoscopic Evaluation of Swallowing (FEES) procedure with a formal sensory test (also known as laryngopharyngeal sensory testing) protocol included used to elicit the Laryngeal Adductor Reflex (LAR) directly using air pulses or direct touch with an endoscope.
Laryngeal videostroboscopy, an imaging technique, is commonly used to view the vocal folds: this procedure can be performed nasally or orally. [11] Vocal fold nodules are most often characterized as bilaterally symmetrical whitish masses, [11] and tend to form at the midpoint of the vocal folds. [12]
Videostroboscopy is a high-speed medical imaging method used to visualize the dynamics of human vocal fold vibration. When stimulated by the pressure of breath exhaled from the lungs, the two vocal folds (also known as vocal cords) open and close rapidly. This process is called phonation and produces the sound of the human voice.
Videokymography complements another visualization method known as videostroboscopy for early diagnostics of voice disorders and therapy evaluation. It has spread as a clinical and research tool to clinics around the world, and kymographic display was adopted also for digital high-speed videoendoscopy.
Laryngeal stroboscopy is the primary clinical tool used for this purpose. Laryngeal stroboscopy uses a synchronized flashing light passed through either a rigid or flexible laryngoscope to provide an image of the vocal fold motion; the image is created by averaging over several vibratory cycles and is thus not provided in real-time.

The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
