This paper reports three cases of 'occult' submucous posterior laryngeal cleft in which MR examination has visualized the deficiency of the posterior cricoid lamina. Laryngeal cleft is an uncommon anomaly, and its clinical and endoscopic diagnosis is always difficult. To our knowledge, the role of MR in this diagnosis has not yet been emphasized.
The authors devised a percutaneous dilatational method which they believe trained physicians and nonphysicians (emergency medical technicians and paramedics) can use with safety and speed. With one blade of a modified nasal speculum embedded in a tapered small pigtail-dilator catheter, the closed, flattened instrument is forced through the cricothyroid ligament, with a twisting motion, and then opened. Only the skin is incised 1 cm in length. Then a free flow of air via attached syringe is sought before any further penetration. This guarantees accurate and safe entry into the airway. The operator forces the J-tipped dilator and speculum inward as the needle is withdrawn. At the proper depth the speculum is opened transversely, and a cuffed tracheostomy tube with an internal diameter of 6 mm is inserted. The instrument is removed and immediate suctioning and active ventilation is possible. The authors developed the use of this instrument in trials on a mannequin and on 25 cadavers.
