Figure 3
Customized tracheostomy cannula. Using 1 E-tube and blade (a), divide the E-tube into 3 segments (b), longest one is for maintaining the airway, and the other is used for stent fixation. The beveled tip and side hole are removed. (c) Two holes are placed at opposing sides of upper end for string attachment. (d) Two holes are then made (front and back) at mid-section, allowing the curved tube to approximate the patient’s neck contours. (e) The airway tube is ultimately inserted and fixed, leaving an appropriate length distally and a 5 cm excess at the proximal end. (f), (g) Both tubes (airway and fixation) together are finally inserted and secured with nylon suture (2.0 or 3.0) (h).
