[Anesthetic management for laryngoscopic evaluation of upper airway stenosis using our modified endoscopic mask].
Young children are at increased risk for hypoxaemia and hypercapnea during flexible laryngoscopy due to the small size and increased collapsibility of their airways. To evaluate upper airway stenosis of a 5-year-old girl presenting with retractive inspiratory breathing, we developed a modified endoscopy mask consisting of a regular face mask where the original port for endoscope was replaced by a disposable rubber dam. This setting allows a leak-free passage of both nasal and oral endoscopy and enables emergent endoscopic intubation through a small hole of a rubber dam. Using this airtightly sealed modified mask, we successfully managed diagnostic endoscopy of laryngomalacia and evaluated infolding of arytenoids under spontaneous ventilation with 100% oxygen.
