Cyanoacrylate Foreign Body of the External Auditory Canal.

Foreign bodies of the ear canal are very common. However, it is uncommon that foreign bodies fully fill the ear canal. There are few reports on foreign bodies filling the external auditory canal. We present a patient with a cyanoacrylate foreign body in the external auditory canal and discuss the diagnosis and treatment. CT scanning was useful to evaluate the condition in the external and middle ear. We removed the foreign body under general anesthesia after we confirmed that the foreign body had no adhesion to the tympanic membrane. We emphasize that it is important to perform appropriate examinations and to make a proper therapeutic policy before operating.
