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 .
An ENT doctor will likely do a laryngoscopy, which is an exam of the throat and voice box using a small camera, she says. You may need a fluoroscopic swallowing study, which involves eating or ...

A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult bag mask ventilation.
Again, when examining the throat of such patients, if everything seemed to be moving well, then clinicians are often befuddled as to what the source of the throat pain is. With sensory testing, one can demonstrate that the throat tissues are numb, signifying some damage to the sensory fibers of the vagus and thereby identify vagus nerve injury ...
The current gold-standard means for diagnosing EILO is the continuous laryngoscopy during exercise test (CLE-test). This test involves the placement of a flexible laryngoscope via nostril, which is then secured in place and held with headgear. It allows continuous visualization of the laryngeal aperture during exercise.
Indirect laryngoscopy can be highly effective, but requires skill and practice for consistent results. For this reason, many specialist clinics now use fibre-optic nasal endoscopy where a thin and flexible endoscope , inserted through the nostril , is used to clearly visualise the entire pharynx and larynx.
Regardless of blade shape, direct laryngoscopy technique involves passage of the laryngoscope through the mouth and into the back of the throat. Manipulation of the neck and lifting of the tongue allows for direct visualization of the larynx and vocal cords by the operator.
