Hypertrophy of the lingual tonsils is an unusual condition that may cause complications such as airway obstruction, abscess, sleep apnea, and recurrent epiglottitis. There have been reports of difficult anesthesic intubation in children with enlarged lingual tonsils. We describe a 24-year-old woman whose markedly hypertrophied lingual tonsils prevented intubation after anesthesic relaxation during preparation for appendectomy.
