목적: Foreign body(FB) ingestion, an everyday occurrence in otorhinolarynglogy caused by various sizes and types of objects, can cause oral and pharyngeal infection, laceration, deep neck abscess, vocal cord palsy and etc according to their impaction sites and duration, and associated diseases. Speedy diagnosis and early intervention are necessary for carefully removing the FB. Therefore, in our department, we researched about most commonly encounted FB and its impaction sites. 방법:A total of 308 patients with a FB sense iin the food passages were treated in the Chonnam National University Hospital emergency department between November 2013 and 2014. Flexible laryngoscophy was used to store pictures of each patient's impaction site. 결과:A total of 308 patients with a FB sense in the food passages visited out department, including 125 patients in whom FB was found through flexible laryngoscophy. Among 183 patient in whom FB was not detected, 21 patients underwent endoscopy gastroduodenoscopy(EGD). Within those patients, 10 patients removed foreign body through the EGD, while surgical intervention under general anesthesia were carried out in 2 patients. Most of the FB were impacted in between tongue base and epiglottis, and tonsil and its inferior pole. Most commonly responsible foreign bodies were fish bone material croaker or yellow corvina, mackerel and Rockfish, in order of incidence. In cases with crab and chicken bone impaction, symptoms were presented while no FB was detected suggesting that esophageal mucosal erosion and pharygneal laceration may be confused with foreign body impaction. Ones without FB detection did not revisited the department and there were no complications due to FB impaction in our cases. 결론:When patients complain FB sense in food passage, a tongue base and peritonsillar region must be throughly examined, and type of FB should be noted for possiblity of mucosal laceration. However, if the symptom persists, we must not hesitate to undergo EGD.
