ObjectivesExercise-induced laryngeal obstruction (EILO) is a prevalent cause of exertional breathlessness and wheeze in young individuals. Typically diagnosed using the continuous laryngoscopy during exercise (CLE) test, treatment is largely based on breathing retraining promoting improved laryngeal function. In some cases, these techniques fail to alleviate symptoms, and surgical intervention with supraglottoplasty can be valuable in the supraglottic form of EILO. Globally, there is currently limited experience utilizing a surgical approach to EILO, and data regarding the optimum surgical technique and published outcomes and complication rates are thus limited.Study DesignRetrospective observational case series.MethodsIn this report, we describe our experience as the only UK center undertaking supraglottoplasty for EILO. We report the surgical outcome of 19 patients (n = 16 female), mean age, 29.6 ± 13.1 years, referred for surgery with moderate to severe supraglottic EILO. Follow-up clinic ± CLE was performed within 4 months (median = 6 weeks), and CLE scores were evaluated before and following surgery.ResultsWe found a beneficial effect of surgery on supraglottic CLE scores (median score reducing from 3/3 to 1/3 postoperatively [P < .05] overall) with 79% (n = 15) of patients reporting an improvement in their exercise capacity. One patient developed an apparent increased tendency for glottic-level EILO following surgery; however, no voice- or swallowing-related complications were encountered.ConclusionsThis study is the first to report the UK experience, surgical technique, and outcome for EILO surgery. The findings indicate that EILO surgery appears to be a safe and effective option for individuals with moderate to severe supraglottic-type EILO who have failed initial conservative treatment.Level Of Evidence5 Laryngoscope, 130:E667-E673, 2020.© 2020 The American Laryngological, Rhinological and Otological Society, Inc.
