  1. Current Trends in Treating the Palatal Air Leak (Stress Velopharyngeal Insufficiency) Dr. Chris Gibson Associate Professor of Music Northwest Missouri State University

  2. What is a Palatal Air Leak? Physical defect, injury or dysfunction. Air leaks through the nose while blowing through the mouth.

  3. S V P I Stress Velo Pharyngeal Insufficiency Incompetence Inadequacy Dysfunction

  4. Velopharyngeal Area Soft Palate Trachea

  5. Characteristics • Young adults, typically students • Intensive practice schedules • Sustained high intra-oral pressure: • Oboe, clarinet, bassoon • Good tonal concept, but with a fault in some small aspect of tonal production • Speech is normal

  6. First Onset Periods of stress or change such as: • Intensive short-term performances • Audition or recital preparation • Changes in routine • Changes in equipment

  7. Current Understanding • Causes not well understood • Relatively few musicians have SVPI • Not all seek treatment • Research limited to case studies • Individualized interventions • Many interventions at least partially successful

  8. Careful Evaluation of: Posture Breathing and breath support Embouchure Formation Instrument Setup Non-Medical Interventions

  9. Non-Medical Interventions Additional Steps • Alexander Technique • Inner smile • Muscular retraining • Relaxation training

  10. Ear-Nose-Throat Specialist Physical evaluation Referral to other professionals Speech Pathologist/Therapist Evaluation Variety and combination of strategies Individualized to address weaknesses Medical Interventions Surgeon – typically last resort • Pharyngeal wall augmentation • Lengthening too-short soft palate • Correcting weakness in sphincter muscle

  11. Endoscopic Video: Normal Soft Palate • Exercises seen: • “Hard” • “Ahhh” • “Kick” • Tongue against soft palate (peanut butter) • Silent blowing through mouth

  12. Endoscopic Video: Normal Soft Palate

  13. Endoscopic Video: SVPI • Exercises seen: • “Duhna” • “Kick” • Nasal speech • Clarinet warm-up with air leak • “Ahhh” • “Pop” • Sucking • “Ahhh” • Mozart with air leak

  14. Endoscopic Video: SVPI

  15. Conclusion • Current research still primarily case-study or small groups • Nonmedical strategies may be effective • Especially muscular retraining • Newer medical procedures offer hope • Fiberoptic endoscopy • Laparascopic (micro) surgery

  16. Future Research • Controlled studies with larger sample sizes. • Studies involving newer technology. • Survey of the population to determine scope and effect.
