AB Endobronchial  and  esophageal  foreign  bodies  are  marked  by  three  clinical  stages—an  initial  symptomatic  stage  of  coughing,  choking,  and  discomfort  and  a  stage  of  relative  amelioration  of  symptoms  followed  by  a  stage  of  complications  due  to  obstruction  and  infection.The  gold  standard  for  the  diagnosis  of  an  endobronchial  foreign  body  is  bronchoscopy.An  asymptomatic  or  mildly  symptomatic  child  with  a  coin  in  the  esophagus  can  be  observed  for  8  to  16  hours  because  the  coin  will  spontaneously  pass  into  the  stomach  in  25%  to  30%  of  these  children.A  useful  method  for  removal  of  most  intranasal  foreign  bodies  is  a  balloon-tipped  catheter  such  as  a  Foley  or  the  commercially  available  Katz  Extractor®.A  useful  initial  method  for  removal  of  most  foreign  bodies  from  the  external  auditory  canal  is  irrigation.  This  technique  requires  very  little  patient  cooperation.An  immobile  battery,  for  example,  in  the  esophagus,  nose,  or  ear,  requires  emergent  removal  to  prevent  perforation  at  the  site  of  impaction  and  subsequent  infection.Two  or  more  rare-earth  magnets  in  the  gastrointestinal  tract  or  on  both  sides  of  the  nasal  septum  require  emergent  removal  because  of  the  potential  of  erosion  and  perforation  of  the  tissue  between  the  two  adherent  magnets.
