The endoscopic Teflon keel for posterior and total glottic stenosis.
Most cases of posterior commissure stenosis today result from endotracheal intubation. The problem has been very difficult to repair. Posterior commissure stenosis has been treated by repeated dilations, which do not work, and reconstructive measures by means of laryngofissure to excise the scar followed by the placement of round stents alone or round stents in combination with mucosal or skin grafts. This treatment also fails frequently. Some, but not all, cases have been cured with laser surgery via microdirect laryngoscopy. An endoscopically placed Teflon keel has been useful in the treatment of posterior glottic and total glottic stenosis when laser surgery is not feasible. Nine patients with posterior glottic stenosis, two of whom initially had total glottic stenosis, have undergone placement of the posterior commissure Teflon keel. Six patients had resolution of the stenosis and were decannulated. One required an arytenoidectomy for a fixed cricoarytenoid joint before successful decannulation. Two patients had marked improvement of their laryngeal airway with this approach, but have not yet been decannulated because of fixed cricoarytenoid joints.
