Eligibility Criteria
Inclusion Criteria:
- Age >18 years
- Symptoms of tracheal or laryngeal stenosis or airway narrowing
- Endoscopic evidence of subglottic or tracheal stenosis
- Able to provide informed consent
Exclusion Criteria:
- Refractory stenosis not amenable to balloon dilatation

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Dilatation
Arm Description
Patients undergoing tracheal dilatation with the study device
Outcomes
Primary Outcome Measures
Incidence of peripheral arterial desaturation
Incidence of desaturation below 90% as measured by peripheral pulse oximeter
Time to desaturation
Time to desaturation below 90% as measured by peripheral pulse oximeter
Secondary Outcome Measures
Efficacy of tracheal dilatation by comparison of pre- and post-dilatation Myer-Cotton grading
Describes the stenosis based on the percent relative reduction in cross-sectional area of the subglottis. Four grades of stenosis: grade I lesions have less than 50% obstruction, grade II lesions have 51% to 70% obstruction, grade III lesions have 71% to 99% obstruction, grade IV lesions have no detectable lumen or complete stenosis.
Incidence of major adverse events

5. Study Description
Brief Summary
The purpose of the study is to prospectively assess the use of a modified tracheal balloon dilator that allows gas flow (oxygenation and ventilation) through the device while inflated during dilatation.
Detailed Description
The primary aim is to determine the incidence of, and time to, arterial desaturation (defined as peripheral plethysmography below 90%). Secondary aims include quantitative and qualitative (waveform) end-tidal capnography levels throughout the procedure, quantitative assessment of dilatation, and incidence of adverse events.
