A new technique for T tube insertion in severe subglottic stenosis.

T tube insertion for subglottic stenosis is often difficult due to bending of the T tube itself. A T tube could be inserted safely and consistently in a patient with severe subglottic stenosis employing a method that we newly devised. Our method can be performed under local anesthesia without special instruments and is technically straightforward. And also, our method is considered to be applicable to marked stenosis and stenosis with a complex morphology. Herein we present an improved method for inserting a silicone T tube through a tracheostomy stoma in patients with severe subglottic stenosis.
