WHAT IS FEES?
Safe & Trusted
FEES (Flexible Endoscopic Evaluation of Swallowing) has been used since the 1980s and is proven to be extremely safe, comfortable, and well-tolerated by patients.
Clear, Real-Time View
A small endoscope is gently passed through the nose, providing a high-definition look at how swallowing and breathing work together—without radiation or barium.
Accurate & Reliable
FEES helps identify airway or throat issues, secretion management, and risks of aspiration, making it a trusted tool for diagnosing swallowing disorders.
Secretion & Aspiration Detection
The exam easily detects secretion buildup and aspiration risk, giving clinicians essential diagnostic information.
High Standards of Care
Each procedure uses single-use equipment and strict infection-control protocols for patient safety.
Patient-Centered
Most patients find the test comfortable, and studies show 98% would choose to repeat it in the future.

Our primary service area includes DFW and East Texas.
