    • Reliability of translaryngeal airway resistance measurements during maximal exercise 

      Fretheim-Kelly, Zoe; Engan, Mette; Clemm, Hege Synnøve Havstad; Andersen, Tiina Maarit; Heimdal, John-Helge; Strand, Eric; Halvorsen, Thomas; Røksund, Ola Drange; Vollsæter, Maria (Peer reviewed; Journal article, 2022)
      Objective Exercise-induced laryngeal obstruction is an important cause of exertional dyspnoea. The diagnosis rests on visual judgement of relative changes of the laryngeal inlet during continuous laryngoscopy exercise (CLE) ...

      Benestad, Merete R.; Drageset, Jorunn; Clemm, Hege Synnøve Havstad; Røksund, Ola Drange; Vollsæter, Maria; Halvorsen, Thomas; Hysing, Mari; Vederhus, Bente Johanne (Peer reviewed; Journal article, 2021)
      Background: Exercise-induced laryngeal obstruction (EILO) is common in young people with exertional breathing difficulties. Psychological characteristics have been proposed as underlying contributors; however, the evidence ...

    • Severe exercise-induced laryngeal obstruction treated with supraglottoplasty 

      Sandnes, Astrid; Hilland, Magnus; Vollsæter, Maria; Andersen, Tiina Maarit; Engesæter, Ingvild Øvstebø; Sandvik, Lorentz; Heimdal, John-Helge; Halvorsen, Thomas; Eide, Geir Egil; Røksund, Ola Drange; Clemm, Hege Synnøve Havstad (Journal article; Peer reviewed, 2019)
