AbstractA 66-yr-old man was scheduled for colon resection under general anesthesia. There were no findings suggesting difficulty of airway management. After induction of anesthesia, manual ventilation via a facemask was suboptimal, but increased fresh gas flow improved it. At direct laryngoscopy after achieving muscular relaxation, the arytenoids and epiglottis could not be seen even by an expert anesthesiologist. Intubating laryngeal mask airway (ILMA) was inserted to patient's larynx and ventilation could be continued. Tracheal intubation through ILMA was impossible because of hard resistance for inserting the endotracheal tube. Fiberoptic bronchoscopy revealed that the hypertrophied lingual tonsil obstructed the aperture of ILMA. Several attempts were made for intubation using fiberoptic tracheal intubation technique through ILMA and finally the patient's trachea was intubated without any bleeding or swelling of laryngeal tissues. The effectiveness of ILMA for the patient with lingual tonsil hypertrophy is still unknown, but the insertion of ILMA might be considered for safe airway management in combination with a fiberscope.
