Laryngomicrosurgery of Large Vocal Fold Polyp by Using a Side-opened Direct Laryngoscope and Snare

Abstract

Eleven cases of large vocal fold polyp were successfully treated with laryngomicrosurgical technique by using a side-opened direct laryngoscope and snare. Postoperative analysis revealed that excellent voice restoration was obtained in all cases. It is thought that an excess removal of the mucous membrane and much bleeding can be avoided by using a snare. When used in cases of laryngomicrosurgery in which bimanual manipulation of a snare and forceps was required, the manipulability of both hands in a side-opened direct laryngoscope was superior to that in a direct laryngoscope with a completely tubular shape.
In this paper, the method was demonstrated with a clinical case presentation and discussed from the viewpoint of the flexibility of the vocal fold mucous membrane and surgical manipulations which may influence on postoperative results.
