No results posted yet for this study

Summary

This study is a feasibility study to see if an ultrasound scan of the vocal cords can detect narrowing of the vocal cords as seen in a condition called inducible laryngeal Obstruction (the vocal cords narrow or close on breathing in, which makes it very difficult to breathe).

Conditions

  • Vocal Cord Dysfunction
  • Asthma Brittle
  • Inducible Laryngeal Obstruction
  • Paradoxical Vocal Fold Motion

Interventions

OTHER

Trans-cutaneous Laryngeal ultrasound (TLUS)

Assessment of the larynx (specifically the vocal cords) with hand held portable ultrasound device to assess the movements of the vocal cords

OTHER

TLUS and simultaneous laryngoscopy

Assessment of the larynx (specifically the vocal cords) with hand held portable ultrasound device to assess the movements of the vocal cords with simultaneous video laryngoscopy (usual care)
