Vocal process avulsion, a rare injury from intubation or trauma, causes voice loss. Early diagnosis and endoscopic repair using varied techniques can restore vocal function.

Area of Science:

  • Otolaryngology
  • Laryngology
  • Surgical Pathology

Background:

  • Vocal process avulsion is a rare complication of laryngeal trauma or intubation.
  • The vocal process, developing separately from the arytenoid cartilage, has a vulnerable fusion plane.
  • This condition can lead to significant dysphonia (voice impairment).

Observation:

  • Subtle findings of vocal process avulsion necessitate close examination of the vocal process-arytenoid relationship.
  • Stroboscopy is a critical diagnostic tool for evaluating vocal process avulsion.
  • Three cases of vocal process avulsion were encountered and treated.

Findings:

  • All three cases were successfully repaired endoscopically.
  • Diverse surgical techniques were employed, including chemical tenotomy with botulinum toxin, closed reduction with fat injection, and open reduction via cordotomy.

Related Experiment Videos

  • The study highlights the variability in surgical approaches for this rare condition.

    • Implications:

    • Accurate diagnosis and tailored endoscopic repair are crucial for managing vocal process avulsion.
    • Understanding the unique anatomy of the vocal process aids in identifying this subtle injury.
    • This research contributes to the management strategies for vocal process avulsion and associated dysphonia.
