[Initial experience with a silicone T-tube of our design in stenoses of the larynx and trachea].

Due to research of plastics in the Research Institute of Cables and Isolates in Bratislava it was possible to develop a T-tube which proved useful in the comprehensive treatment of laryngotracheal stenoses at the ENT Clinic of the Faculty Hospital. The advantage of the prototype of the silicon laryngotracheal T-tube is the ovoid shape of the horizontal arm which makes it possible to treat more readily the upper and lower arm. Closure of the horizontal arm permits normal respiration and phonation. The smoothness of the tube wall prevents adherence of mucus and formation of crusts in the tube. The biological inertness and adequate consistency of the T-tube permit epithelialization of the supported areas of the larynx and trachea without formations of excessive granulation tissue. In the submitted paper the authors describe their experience with the use of the silicon T-tube of their own design in three patients with laryngeal stenosis and stenosis of the cervical portion of the trachea.
