Summary
Objective
This study aimed to determine the value of laryngeal electromyography in the prognosis
of vocal fold paralysis.
Study Design
This is a retrospective descriptive study.
Materials and Methods
This study included 80 patients diagnosed with unilateral or bilateral vocal fold
paralysis on flexible laryngoscopy between 2002 and 2014 in a tertiary medical center.
Laryngeal electromyography using a standardized protocol was performed; the outcome
measures were classified and analyzed into two groups according to the degree of injury.
Group 1 included patients with mild to moderate injury, and group 2 included patients
with severe to complete injury. Prognosis was correlated with vocal fold motion recovery
status with a minimum of 6 months of follow-up since the symptoms onset using positive
and negative predictive values.
Results
Sixty patients showed acute or chronic recurrent laryngeal neuropathy in laryngeal
electromyography. Twelve of 41 patients included in group 1 recovered motion, and
30 of 35 patients included in group 2 did not recover, resulting in 88.2% of positive
predictive value and 35.7% of negative predictive value.
Conclusions
Our data confirm that laryngeal electromyography is a useful clinical tool in predicting
poor recovery in patients with vocal fold paralysis. It allows identification of candidates
for early intervention.
