Impaction of foreign bodies in the upper aerodigestive tract is commonly encountered in ENT practice. The present paper describes an iatrogenic complication with migration of an impacted foreign body (chicken bone) of the hypopharynx into the prevertebral space, after unsuccessful attempt of endoscopic removal. The foreign body was visualized with cervical CT scan lying extraluminally between the major vessels of the neck. An open surgical procedure with neck exploration was necessary for the definite treatment.
