The procedure is typically performed by a speech-language pathologist or a trained nurse under the supervision of a physician. It involves the following steps:
The patient is seated in an upright position. A topical anesthetic may be applied to the nasal passages to minimize discomfort. The endoscope is gently inserted through the nose and advanced to the level of the soft palate. The patient is asked to swallow various consistencies of food and liquid while the examiner observes the swallowing process on a monitor. The procedure usually takes about 20-30 minutes.
