INTRODUCTION: Continuous laryngoscopy during exercise (CLE) is increasingly used to diagnose exercise induced laryngeal obstruction (EILO). One barrier to widespread implementation is reliable fixation of the flexible laryngoscope during exercise. This study describes the development and validation of an adjustable, low-cost helmet constructed from commercially available and 3D-printed components to facilitate CLE in a pediatric EILO clinic.
MATERIALS AND METHODS: An adjustable CLE helmet was developed using 3D-printed and commercially available materials. Eight otolaryngologists at a tertiary pediatric hospital performed initial testing for fit and function validation. The helmet was then implemented in a multidisciplinary pediatric clinic for patients with suspected EILO.
RESULTS: Otolaryngologists completed surveys after a simulation session with the helmet. Using a 5-point Likert scale, they rated the helmet "easy to use" with "good realism" (median 4, IQR 4-5), and "complete comfort" using it in practice after simulation (median 5, IQR 4-5). The helmet was successfully used during CLE in 27 patients (ages 12-20 years, mean 15.9) without complication or readjustment during CLE. Mean exam duration was 26.9 ± 9.3 min. EILO was diagnosed in 96% (n = 26) of patients, with Maat scores of Grade I in 4 (15%), Grade II in 14 (54%), and Grade III in 8 (31%). Biofeedback therapy was used for EILO management during CLE.
CONCLUSION: This data demonstrates face validity and clinical utility of an adjustable, 3D-printed helmet for CLE in a pediatric EILO clinic. This open-source solution may reduce technical barriers and expand access to CLE for EILO evaluation and management.
