Difficult Intubation in Pediatric Patient with a Large Lymphangioma at the Tongue Base.

Lymphangioma is a congenital malformation of lymphatic system and often involves the oral cavity. When lymphangioma is located on the mouth floor and enlarges, it can compress the airway and make intubation difficult. The GlideScope(®) video laryngoscope is sometimes used in routine intubation, but is most commonly used in difficult or failed intubation. We report a pediatric patient with a difficult intubation due to a large tongue base mass. The airway was compromised due to limited intraoral space, large mass at the tongue base, and glottis distortion. Oral approach was not successful with the Macintosh laryngoscope. In this case, a rigid stylet was made to match the GlideScope(®) curve and the endo-tracheal tube was inserted through the glottis under GlideScope(®) guidance. We believe that, even in pediatric patients, a rigid stylet is necessary when intubation at a sharp posterior angulation to the trachea is difficult during GlideScope(®) approach.
