To analyze existing evidence regarding utility of laryngeal electromyography (LEMG) for prognosis in cases of vocal fold palsy (VFP).Abstract:
Objectives/Hypothesis:
To analyze existing evidence regarding utility of laryngeal electromyography (LEMG) for prognosis in cases of vocal fold palsy (VFP).
Study Design:
Meta-analysis of studies reporting LEMG results and clinical outcomes in 503 patients with of VFP identified by literature search.
Methods:
Studies were identified by literature search. Method of diagnosis, interval to LEMG, criteria for prognostication, and outcome were assessed. Criteria for prognosis were standardized to the extent possible across all studies, and studies were checked for consistency in outcome measures and assessments. Pooled data were subjected to statistical analysis.
Results:
A total of 296/503 patients (58.8%) had findings predictive with poor prognosis, whereas 207/503 (41.2%) had findings of recovery. According to laryngoscopic examination, 269/296 patients with predicted poor recovery had poor recovery (positive predictive value = 90.9%), whereas 27/296 (9.1%) had good recovery. In patients with findings consistent with recovery, 115/207 (negative predictive value = 55.6%) noted return of motion, whereas 88/207 (44.4%) did not. The odds ratio was 11.56 with 95% confidence interval of 7.10-18.81.
Conclusions:
LEMG is a good predictor of poor recovery in patients with VFP and is clinically useful in identifying candidates for early definitive intervention.read more

Evidence-Based Practice: Evaluation and Management of Unilateral Vocal Fold Paralysis
TL;DR: In this paper, the causes and symptoms, evaluation, and management of unilateral vocal fold paralysis (UVFP) were discussed, and cross-sectional imaging was used in the work-up of idiopathic UVFP.

TL;DR: A laryngeal electromyography working group of European neurolaryngologic experts was formed in order to evaluate guidelines for LEMG performance and identify issues requiring further clarification as mentioned in this paper.

Unilateral Vocal Fold Paralysis: A Systematic Review of Speech-Language Pathology Management
TL;DR: There is presently a lack of methodological rigor and clinical efficacy in the speech-language pathology management of dysphonia arising from UVFP in adults, requiring further research to develop the evidence for the management of UVFP incorporating controlled treatment protocols and more rigorous clinical methodology.

Recovery of laryngeal function after intraoperative injury to the recurrent laryngeal nerve
TL;DR: This review aims to provide an update on the current understandings of surgically-induced injury to the laryngeal nerves to clarify any differences between the transient and permanent injury of the RLN.

Laryngeal synkinesis: its significance to the laryngologist.
TL;DR: Patients thought to have clinical bilateral vocal cord paralysis can be found to have synkinesis on at least one side, which will make the glottic airway smaller, particularly during inspiration, than would true paralysis of all the intrinsic laryngeal muscles.

Prognostic Value of Laryngeal Electromyography in Vocal Fold Paralysis
TL;DR: The detection of neural degeneration by laryngeal electromyography allows the prediction of poor functional outcome with sufficient reliability in an early phase of the disease process.

TL;DR: The objective is to identify clinical evidence regarding outcome and duration of unilateral idiopathic vocal fold paralysis (IVFP) and to establish a smoking cessation strategy for this disease.
