OBJECTIVES: To determine the value of laryngeal electromyography in predicting recovery after @entity912 and to determine what elements of laryngeal electromyography are most predictive of outcome. DESIGN: Cohort study with retrospective data review. SETTING: University voice center. @entity1 : Consecutive sample of 31 @entity1 with @entity912 diagnosed by indirect laryngoscopy, using either nasal insertion with a flexible nasopharyngoscope or peroral with a 70 degrees Hopkins rod. Inclusion criteria were that laryngeal electromyography had to have been performed between 21 days and 6 months from the onset of symptoms and @entity1 must have been followed a minimum of 6 months. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Vocal fold motion at 6 months from onset of symptoms. RESULTS: Nine subjects (29%) had resolved vocal fold motion, whereas 22 (71%) had persistent @entity912 . By using our laryngeal electromyography paradigm, 4 of 6 @entity1 with a laryngeal electromyography prognosis of excellent resolved. The predictive value for a negative test was 66.7%. For @entity1 with a fair or poor prognosis, 5 of 25 resolved. The predictive value for a positive test was 80%. Only 8 of 22 @entity1 with persistent @entity912 had fibrillations, and spontaneous activity was not significantly related to outcome. @entity1 with absent or greatly decreased motor unit recruitment had a significantly higher proportion of permanent @entity912 (P<.05). Stepwise forward logistic regression determined that prognosis by laryngeal electromyography and onset time were significant predictors of outcome (P<.01). The model predicted 44.4% of resolved cases, which represents a moderate prediction. CONCLUSIONS: This study confirms the utility of laryngeal electromyography in assessing prognosis for recovery of vocal fold motion after @entity13587 . The results support our hypothesis that preset decision rules based on laryngeal electromyography data can be effectively used to determine a prognosis for recovery of vocal fold motion.
