Abstract
Background: A fish bone lodged in the oral cavity is in most cases removed simply; but, if it migrates, surgical intervention is necessary.
Case Report: We report a case of deep neck infection caused by the migration of a fish bone which was not removed initially, as well as a case of a huge fish bone migration found by chance along with complaints about mild symptoms. As there was no specific finding in simple X-ray examination and endoscopy, both of the 2 cases were diagnosed with neck CT. The fish bones were removed with surgical exploration through lateral neck incision and the patients were discharged without any significant sequela.
Conclusions: For patients swallowing a fish bone, even though there is no abnormality in physical examination, simple X-ray and endoscopy, diagnosis should be made early through neck CT by considering the possibility of fish bone migration. A surgical approach is needed to avoid any damage to the major structures.
