Flexible Fiber-Optic Laryngoscopy (FLL) or Nasopharyngoscopy
This quick, in-office procedure 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. 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.

Advantages:
No radiation, anesthesia, or sedation.
In-office procedure.

Brief procedure, usually only taking a few minutes.
