Electromyography in Children's Laryngeal Mobility Disorders

Clinical and Electromyographic Characteristics of Pediatric Laryngeal Dyskinesia

“…The remaining were missing LEMG, swallowing, and sleep oximetry data. Twenty-nine were included (4 of whom were reported previously by AlQudehy et al 6 ), 20 of whom were males, and the median age at presentation was 9.83 months (range 0.42-116.58 months). The prevalence of LD was 28.21% among all LMD cases who required full airway endoscopy under general anesthesia, and those included constitute 18.58%.…”

“…The patients were identified from a prospective surgical database kept by 1 surgeon. This database contains information on the demographics, diagnoses, procedures, complications, and special equipment settings (data from some of the patients within this cohort have been published elsewhere) 6 . Prior to embarking on the study, permission was granted by the University of Alberta Human Health Research Ethics Board (Pro00117418).…”

Isolated neonatal bilateral vocal cord paralysis revealing a unilateral medullary defect: a case report

“…Laryngeal electromyography can also help to better characterize laryngeal motility disorders and anticipate the prognosis of bilateral laryngeal palsies. Interpretation, however, is not fully standardized in neonates and children [ 11 ].…”

Comparison of inhaled versus intravenous anesthesia for laryngoscopy and laryngeal electromyography in a rat model

“…As part of the reporting practice, the type of anesthetic used throughout the procedure should be documented [ 42 ]. Proponents of LEMG argue its prognostic and diagnostic values that may guide treatment decisions in patients with vocal fold mobility disorders [ 37 , 43 ].…”

“…Multiple intrinsic laryngeal muscles were described in the literature as a point for recording LEMG activity in both animals and humans. This includes thyroarytenoid [ 9 – 12 , 15 – 18 , 33 , 36 – 39 , 44 – 49 ], cricothyroid [ 44 , 46 , 48 , 50 ], PCA [ 11 – 13 , 15 , 16 , 18 , 27 , 32 , 33 , 37 , 38 , 44 , 45 , 49 , 51 , 52 ] and lateral cricoarytenoid [ 15 ] either individually or in combination. The authors have selected the PCA muscle, as it’s the single laryngeal muscle responsible for vocal fold abduction.…”
