Intraoperative Laryngeal Electromyography in Children With Vocal Fold Immobility<subtitle>Results of a Multicenter Longitudinal Study</subtitle>

Abstract

Intraoperative LEMG is a safe, easy-to-use method for determining the likelihood of recurrent laryngeal nerve function return in children who have undergone patent ductus arteriosus ligation, in children with centrally correctable lesions, and in children with idiopathic VFI. More work is needed in the area of pediatric LEMG, but it is possible that LEMG data can be used to aid in management strategies and provide families with more information to make better informed decisions regarding their child's care.

Unilateral Vocal Fold Paralysis After Congenital Cardiothoracic Surgery: A Meta-analysis

“…Additional techniques for vocal fold function assessment may include extubation followed by direct laryngoscopy and rigid bronchoscopy, laryngeal electromyography, or laryngeal ultrasound. Maturo et al 39 prospectively showed that laryngeal electromyography could predict recurrent laryngeal nerve function return when compared with diagnosis by flexible fiberoptic laryngeal examination. The authors reported this technique to be a safe, operator-friendly method for determining the likelihood of function return in a variety of patients, including those who had undergone PDA ligation.…”

Spontaneous recovery of bilateral congenital idiopathic laryngeal paralysis: Systematic non-meta-analytical review

“…Eighteen articles reported adult or mixed adult and pediatric population without a separate analysis [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. Sixteen articles had flaws that disqualified them from inclusion (sampling, diagnostic definition, incomplete follow up, and non-objective assessment of final outcome) [2,4,[6][7][8]14,[67][68][69][70][71][72][73][74][75][76]. Twenty-one articles were assessing glottic expansion procedures on highly selected groups [9,[77][78][79][80][81][82][83][84][85][86][87][88][89][90]…”

Electromyography in Children's Laryngeal Mobility Disorders

“…On reviewing the titles and abstracts produced, only 8 articles were found suitable to evaluate. 3,[6][7][8][9][10][11][12] We reviewed these references critically with respect to sample size, study design, technique, muscles sampled, use of a scale/grading for the findings, diagnoses assessed, conditions of anesthesia, and whether serial measurements took place ( Table 5). We will comment on one of these studies 9 separately because the conditions of the experiment were very different.…”

“…Regarding the specific anesthesia protocol, the latest 3 studies (by Scott et al, 3 Jacobs and Finkel, 8 and Maturo et al 12 ) abandoned the previously used inhalational technique, which potentially can affect laryngeal movement, and used intravenous agents, allowing better control of the duration and depth.…”

“…All the cited studies were noncontrolled and retrospective (aside from those by Ysunza et al 11 and Maturo et al 12 ). The sample sizes varied between 4 and 32 patients (median, 10 patients).…”
