Postcricoid mucosal advancement flap for posterior glottic stenosis

Surgical management of posterior glottic stenosis is challenging. The posterior glottis can be approached either through an open laryngofissure or endoscopically. The postcricoid mucosal advancement (PCMA) flap), first described by Montgomery (Montgomery, Arch Otolaryngol 98:170-175, 1973), is a reconstructive technique that can be combined with either of these approaches, enabling resection of posterior glottic scar while preserving or improving voice and swallowing function. This article will describe the open technique, its indications, and its potential complications.
