History of Fiberoptic Endoscopic Evaluation of Swallowing for Evaluation and Management of Pharyngeal Dysphagia: Changes over the Years
A Personal Note - Back in 1988, when the first description of the FEES procedure was published , otolaryngologists had just started to use fiberoptic laryngoscopes in their practice. Prior to fiberoptic technology, laryngoscopy was performed with a mirror or more invasive direct laryngoscopy instruments. The first fiberoptic laryngoscope is generally credited to Sawashima and Hirose in 1968. It transformed the practice of laryngoscopy by allowing a transnasal approach with the patient conscious during the procedure and providing a view of the vocal folds during natural speech.
