    Summary

    Recurrent laryngeal nerve section significantly improved spasmodic dysphonia in patients unresponsive to conventional voice therapy. This surgical intervention offered relief from vocal spasticity, enhancing phonation.

    Area of Science:

    • Otolaryngology
    • Neurology
    • Speech and Language Pathology

    Background:

    • Spasmodic dysphonia is a severe phonation disorder causing vocal tension.
    • Conventional treatments like psychotherapy and speech therapy have shown limited success.
    • Surgical intervention, specifically recurrent laryngeal nerve section, was previously reported with positive outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of recurrent laryngeal nerve section for spasmodic dysphonia.
    • To assess outcomes in patients who did not respond to traditional voice therapies.
    • To document the results of this surgical approach at the Cleveland Clinic.

    Main Methods:

    • Retrospective review of 22 patients with spasmodic dysphonia treated at Cleveland Clinic.

    Related Experiment Videos

  • All patients had a history of at least one year with the condition.
  • Patients underwent recurrent laryngeal nerve section after failing conventional voice therapy.

    • Main Results:

    • Recurrent laryngeal nerve section led to marked improvement in voice quality.
    • Patients experienced significant relief from vocal spasticity post-surgery.
    • None of the patients showed improvement with prior conventional voice therapy.

    Conclusions:

    • Recurrent laryngeal nerve section is an effective treatment for spasmodic dysphonia.
    • Surgery offers a viable solution for patients refractory to non-surgical interventions.
    • This surgical approach provides substantial relief from the debilitating symptoms of spasmodic dysphonia.
