Difficult laryngoscopy and tracheal intubation due to calcified stylohyoid ligaments

Two cases of difficult laryngoscopy and tracheal intubation caused by calcified stylohyoid ligaments are presented. Neither patient exhibited a skin crease over the hyoid bone. It is suggested that inability to lift up the epiglottis from the posterior pharyngeal wall be taken as a more useful sign of this condition than the presence of the skin crease.
