Abstract

OBJECTIVES:

To determine whether laryngeal electromyography (LEMG) can predict recurrent laryngeal nerve function return in children and whether LEMG can aid in the management of vocal fold immobility (VFI).

DESIGN:

Prospective case series.

SETTING:

Tertiary pediatric aerodigestive centers.

PATIENTS:

Twenty-five children aged 14 days to 7 years at the time of first LEMG (mean age, 21.4 months) with VFI who underwent flexible fiberoptic laryngeal examination, intraoperative LEMG of the thyroarytenoid muscles, and 12-month follow-up.

MAIN OUTCOME MEASURES:

To compare results of LEMG with flexible fiberoptic laryngeal examination in children with vocal fold paresis and to determine if LEMG can predict vocal fold return.

RESULTS:

In children who had a patent ductus arteriosus ligation, the LEMG data suggest that if there is no activity 6 months after injury, then the nerve is unlikely to regain function. In 3 of 3 children with central causes of VFI, normal LEMG findings predicted return of nerve function 2 to 7 months before vocal fold movement on fiberoptic examination. Finally, in 3 of 3 children with idiopathic VFI, LEMG predicted return within 2 to 14 months of vocal folds with normal findings.

CONCLUSIONS:

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.
