Diagnosis

Flexible Scope

A flexible scope is usually a quick, in-office procedure that allows an ENT to examine the upper airway above the vocal cords, including the nose, back of the throat (pharynx), and upper parts of the larynx and esophagus.

Formally, a flexible scope is typically called:

  • Flexible Fiber-Optic Laryngoscopy (FFL); or

  • Nasopharyngoscopy.

During the procedure, the ENT inserts a thin, flexible scope into the child’s nose and continues on to view the upper airway. Since the child is awake, their vocal cords can be assessed for proper movement, as well as other conditions. Sometimes a numbing medication is sprayed into the nose before the procedure. An FFL is sometimes performed during an initial consultation with an ENT.

FLL Scope

Location: Usually clinic office

Advantages: 

  • No radiation, anesthesia, or sedation. 

  • In-office procedure. 

  • Allows for the assessment of vocal cord movement. 

  • Brief procedure, usually only taking a few minutes.

Disadvantages: 

  • Cannot see past the vocal cords, so cannot diagnose a laryngeal cleft or other lower airway issues. 

  • The patient is awake and may experience mild discomfort.
