Endoscopic technique to mark the site of tracheal stenosis for resection

It is difficult to precisely localise the extent of the diseased segment on the external aspect of a stenotic trachea. A technique has been developed of marking the upper margin of stenosis, in order to open the airway at the appropriate level during segmental resection.

Prior to the open reconstructive procedure, the stenosis is visualised using microlaryngoscopy. An endo-extraluminal technique is used to drive a suture from inside out through the skin; this then serves to mark the exact top margin of the stenotic segment. This suture serves as a guide for the surgeon during the open approach to tracheal resection.

This technique was performed in 16 cases, and allowed precise localisation of the stenosis in each case.

Transcutaneous localisation of laryngotracheal stenosis, using the Lichtenberger device, is an easy and reliable technique requiring a minimum of additional time.
