Abstract

This study describes a simple extraendolaryngeal technique to apply laryngeal keel in dealing with anterior commissure web/fibrosis. Standard extraendolaryngeal punctures were applied via 20-gauge needles, 30° from the skin surface, in midline through the cricothyroid and thyrohyoid membranes. These needles were used as a conduit for the passage of 2/0 Prolene threads, which were retrieved through the laryngoscope by crocodile forceps. Both laryngoscopic ends of the Prolene threads were passed through a fabricated silastic sheet (keel stent) via a 22-gauge free needle, and these ends were tied to have a secure internal knot. Steady traction was applied on the other 2 external threads until there was appropriate application of this keel stent within the vicinity of anterior commissure. Finally, these external ends were tied to have a secure external knot. A keel stent could be applied without the need for special instrumentation and with reasonable outcomes (proper healing of anterior commissure, satisfied voice outcome, and patent airway).

Keywords: anterior commissure; extraendolaryngeal puncture; glottic web; keel stent.
