Patients with grade IV stenosis have significant quality of life impairments since they are tracheostomy dependent and aphonic. Open airway surgery is often needed to improve tracheal patency, restore the patient's voice, and progress towards decannulation (Abouyared et al., 2017 [<span><span>2</span></span>]). However, not all patients are candidates for upfront open surgery (Abouyared et al., 2017; Shamji, 2018 [<span><span>2</span></span>,<span><span>3</span></span>]).

Briefly, our approach utilizes dual (proximal &amp; distal) visualization of the stenosis prior to passing a 25 gauge needle through the stenosis to identify the proper trajectory for recannulation. Then a 16 gauge needle is passed in the same manner, and a wire is placed through the needle and into the distal airway. Once the airway is recannulated, the initial pinpoint opening is gradually widened in Seldinger fashion over the wire with Savary dilators followed by balloon dilation.
