Cricothyroidotomy can cause voice dysfunction. This study found that 9 out of 19 patients experienced voice problems after the procedure, suggesting elective cricothyroidotomy should be avoided for those with high voice demands.

Area of Science:

  • Otolaryngology
  • Speech and Voice Science

Background:

  • Cricothyroidotomy is a medical procedure that can lead to voice dysfunction.
  • Limited detailed research exists on the long-term voice outcomes following cricothyroidotomy.

Purpose of the Study:

  • To investigate voice function in patients who have undergone cricothyroidotomy.
  • To analyze the prevalence and nature of voice dysfunction after this procedure.

Main Methods:

  • Interviewing 19 patients who underwent cricothyroidotomy.
  • Performing laryngoscopy, stroboscopy, phonetography, fundamental frequency analysis, perceptual voice assessment, and cricothyroid muscle electromyography.

Main Results:

  • Four patients exhibited mild to moderate voice dysfunction due to diminished tensor effect on vocal folds.

Related Experiment Videos

  • Five patients presented with other voice disorders.
  • Ten patients maintained normal voice function.

    • Conclusions:

    • Elective cricothyroidotomy may negatively impact voice function.
    • Patients with vocally demanding professions or activities should consider alternatives to elective cricothyroidotomy.
