Flexible nasendoscopy effectively evaluates velopharyngeal function in patients with cleft palate and other related dysfunctions. This diagnostic tool aids in recommending appropriate treatments, including surgery and speech therapy.

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology
  • Pediatric Surgery

Background:

  • Velopharyngeal sphincter (VPS) function is crucial for speech and swallowing.
  • Flexible fibre-optic nasendoscopy is a key diagnostic method for VPS assessment.
  • The cleft palate team at Withington Hospital has utilized this technique since 1989.

Purpose of the Study:

  • To evaluate the utility of flexible fibre-optic nasendoscopy in assessing velopharyngeal function.
  • To determine treatment recommendations based on nasendoscopic findings in a diverse patient cohort.
  • To identify previously undiagnosed conditions like submucous clefts.

Main Methods:

  • Prospective evaluation of 76 patients referred for velopharyngeal function assessment.
  • Flexible nasendoscopy attempted in 50 patients, successfully completed in 43.

Related Experiment Videos

  • Patients categorized into cleft palate and non-overt cleft palate-related dysfunction groups.

    • Main Results:

    • Successful nasendoscopic evaluation in 43 patients (age 4-77 years).
    • Treatment recommendations included pharyngoplasty (40%), speech therapy (35%), revision pharyngoplasty (11%), obturator (9%), and tonsillectomy (2%).
    • Two previously undetected submucous clefts were diagnosed.

    Conclusions:

    • Flexible nasendoscopy is a valuable tool for diagnosing velopharyngeal dysfunction.
    • Findings guide personalized treatment plans, improving patient outcomes.
    • Early diagnosis of conditions like submucous clefts is facilitated by this method.
