Unusual Foreign Body in 3 Cases Removed with Difficulty

We have experienced unexpected foreign bodies in 3 cases located in the larynx, pharynx and esophagus. The removal procedure and approach for foreign bodies, such as the separation of fish bone by folding in the first case, careful searching of foreign body location in the second case and the abdominal approach for extra large foreign body in the third case must be considered before the treatment. In addition, daily care must be taken for patients with psychologic disorders.
