[Case of airway management by laryngeal mask airway for a child with laryngeal web undergoing adenotonsillectomy].

We report a case of airway management by laryngeal mask airway (LMA) for a 4-year-old boy with laryngeal web undergoing adenotonsillectomy. Although the patient had no symptoms of airway stenosis, we detected a subglottic laryngeal web during the preoperative examination. The opening orifice of the laryngeal web was estimated to be too small for intubation, and we chose to manage the airway with LMA and spontaneous respiration. Using the LMA and Davis-Crowe mouth gag, we were able to provide the surgeon with the same exposure as with intubation while effectively managing the airway.
