Velopharyngeal dysfunction: evolving developments in evaluation

Area of Science:

• Speech-Language Pathology
• Otolaryngology
• Medical Imaging

Background:

• Velopharyngeal valving disorders impact speech and require accurate diagnosis.
• Otolaryngologists play a key role in evaluating these disorders.

Purpose of the Study:

• To review current methods for assessing velopharyngeal function.
• To inform differential diagnosis, treatment planning, and outcome assessment.

Main Methods:

• Direct visualization techniques including nasendoscopy and videofluoroscopy.
• Magnetic resonance imaging (MRI) for anatomical and functional evaluation.
• Instrumental assessments for surgical planning and outcome prediction.

Main Results:

• Nasendoscopy and videofluoroscopy are the most common direct visualization methods.
• MRI offers valuable insights but faces practical limitations (cost, routine use).
• Nasendoscopy is likely to remain prevalent due to cost and radiation concerns.

Conclusions:

• No single method is universally best for evaluating velopharyngeal function.
• The choice of evaluation protocol should align with specific clinical information needs.
• These methods are increasingly utilized by otolaryngologists for diagnosis and treatment guidance.
