Velopharyngeal dysfunction (VPD) involves complex causes and treatments affecting speech. This review covers pathophysiology, diagnostics, and therapies for hypernasal and hyponasal speech.

Area of Science:

  • Speech-Language Pathology
  • Otolaryngology
  • Medical Genetics

Background:

  • Velopharyngeal dysfunction (VPD) presents significant challenges in speech production.
  • Understanding the intricate pathophysiology and diverse etiologies of VPD is crucial for effective management.
  • This review synthesizes current knowledge on structural, neurologic, and other contributing factors to VPD.

Observation:

  • Hypernasal resonance and articulation disorders are primary manifestations of VPD.
  • Hyponasal speech characteristics, though secondary in focus, are also examined.
  • Clinical appraisal methods are detailed for accurate diagnosis.

Findings:

  • A comprehensive overview of velopharyngeal pathophysiology is presented.
  • Various structural and neurologic causes of VPD are elucidated.

Related Experiment Videos

  • Behavioral, prosthetic, and medicosurgical treatment options are discussed.

    • Implications:

    • This tutorial provides a valuable resource for clinicians managing patients with VPD.
    • Improved understanding can lead to more tailored and effective treatment strategies.
    • Addressing both hypernasality and hyponasality enhances the scope of care for speech disorders.
