About FEES

Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is a valid and reliable instrumental assessment of swallowing function performed at the bedside or clinic using a flexible endoscope.

FEES vs. MBSS

FEES complements the Modified Barium Swallow Study (MBSS). FEES provides direct visualization of pharyngeal and laryngeal structures, secretion management, and airway protection across real foods and liquids without radiation exposure.

Procedure

Brief nasal endoscopy with the scope positioned above the epiglottis
Baseline exam of anatomy, movement, and secretions
Systematic trials across consistencies and volumes
Assessment of airway protection, residue, and sensation

Indications

Suspected dysphagia impacting safety or efficiency
Need to assess secretion management and airway protection
Repeatable, radiation-free follow up and biofeedback
