Learning objectives Highlight the importance of the videofluoroscopy swallow study (VFSS) in the evaluation of patients with dysphagia. Recognise different components of normal swallow physiology Identify common functional and anatomic abnormalities of swallowing to guide rehabilitative management of dysphagia.
Read more Background Dysphagia is a debilitating condition that can lead to severe complications such as malnutrition, dehydration, aspiration pneumonia, and even death. The prevalence of dysphagia increases with age and is commonly a result of various medical conditions and their associated treatment complications.The current gold standard investigation for diagnosing dysphagia is the Videofluoroscopic Swallow Study(VFSS), a dynamic fluoroscopic study often performed in collaboration between speech therapists and radiologists.The use of fluoroscopy makes it possible to visualise bolus flow through the aerodigestive tract...
Read more Findings and procedure details Normal swallow physiologyIn order to identify abnormal swallow, one needs to recognise the normal phases of swallowing. Normal swallow physiology can be divided into 3 phases: Oral Phase Pharyngeal Oesophageal The detailed components of each phase are shown below: [fig 1] [fig 2] [fig 3] [fig 4] [fig 5] [fig 6] [fig 7]  Common swallowing abnormalities can be classified based on which phase of swallowing they occur in.Oral phase Anterior loss Contrast is seen spilling out anteriorly from the mouth. Suggests weakness of orbicularis oris resulting in inadequate lip closure. Causes inclue: facial nerve palsy, myotonic dystrophy and myasthenia gravis. [fig 8] Sublingual loss Contrast is seen...
Read more Conclusion The VFSS allows comprehensive assessment of oropharyngeal dysphagia and risk of aspiration. VFSS is useful in providing a preliminary evaluation of oesophageal motility.  A good understanding of swallow physiology is important to correlate signs seen on VFSS to the underlying cause. VFSS is essential to provide guidance for dysphagia rehabilitation and management.
