Supraglottoplasty for laryngomalacia using microscissors

Abstract

Sever laryngomalacia required surgical management; supraglottoplasty. Supraglottoplasty using laser is reportedly effective treatment for laryngomalacia with redundant arytenoid mucosa. However we don’t have a special laser tubes for infants and children. Therefore, we can’t use a laser to avoid a respiratory burn. We performed the supraglottoplasty with one of the cold instruments, microscissors, under the general anesthesia using a conventional plastic tube.

We observed the supraglottis after oral intubation. The supraglottoplasty is performed focusing on removal of the redundant arytenoid mucosa and on divide of the aryepiglottic folds. There is little bleeding during operation, and it is easy to stop bleeding. We didn’t observe the laryngeal edema at the postoperatively 1^st day, and we did the extubation.

We think that the supraglottoplasty is successfully performed using the only microscissors.
