The Annals of Otology, Rhinology, and Laryngology
|September 1, 1983
Summary
Laryngeal nerve crush surgery offered temporary relief for spastic dysphonia patients. However, long-term success rates were low, making this treatment approach no longer recommended for this condition.
Area of Science:
- Neurology
- Otolaryngology
- Speech Science
Background:
- Spastic dysphonia is a neurological voice disorder.
- Treatment options for spastic dysphonia have evolved over time.
Purpose of the Study:
- To evaluate the long-term efficacy of laryngeal nerve crush for treating spastic dysphonia.
Main Methods:
- Twenty-two patients diagnosed with spastic dysphonia underwent laryngeal nerve crush surgery.
- Patient outcomes were assessed at initial follow-up and at a 3-year mark.
Main Results:
- All patients experienced initial improvement following the surgical procedure.
- Only 13% of patients maintained successful outcomes at the 3-year follow-up.
- The majority of patients did not sustain long-term benefits.
Conclusions:
- Laryngeal nerve crush provides only transient improvement for spastic dysphonia.
- Due to poor long-term efficacy, laryngeal nerve crush is not currently advocated for spastic dysphonia treatment.
