[Flexible endoscopic evaluation of swallowing in neurology].

BACKGROUND

Neurogenic dysphagia is a frequent symptom in a variety of neurological diseases. The establishment of the flexible endoscopic evaluation of swallowing (FEES) in the field of neurology has led to improvements in the diagnostics and treatment of patients with dysphagia.

OBJECTIVE

The aim of this review is to present the development of the FEES examination in the field of neurology. Furthermore, the additive value in the diagnostic classification of neurogenic dysphagia is elucidated and the impact on treatment management in patients with dysphagia is highlighted.

MATERIAL AND

METHODS

Narrative literature review.

RESULTS

The FEES examination is a safe and well-tolerated method for the diagnostics of neurogenic dysphagia. It enables the valid investigation of the swallowing function within the very heterogeneous neurological patient population. It has become an important diagnostic tool, not only in the assessment of the severity of dysphagia and the risk of aspiration but also as a reliable method for the etiological classification of symptoms of deglutition disorders. As FEES can be performed at the bedside and does not require radiation exposure, it can be used not only to examine critically ill patients (point of care diagnostics) but also to monitor treatment.

CONCLUSION

The systematic endoscopic evaluation of swallowing is established as an important functional diagnostic tool in the field of neurology. Further developments to increase the use of FEES in clinically related disciplines such as neurosurgery, neuro-oncology or psychiatry are pending.
