Fish bone may be mistaken for a strand of saliva.,Pharyngeal Foreign Bodies,Treatment Perform oral removal as out pat

Endoscopy if object visible but not accessible or if no foreign body seen and symptoms persist beyond 4-5 days.,Esophageal Foreign Bodies,Presentation Sensation of something “sticking” after swallowing. This may result in severe dysphagia with inability

7、to swallow even saliva. Diagnosis Fiberoptic exam to rule out pharyngeal foreign body Plain films for radio opaque foreign bodies, such as coins Barium swallow Barium “burger”, marshmallow, or barium soaked pledgets.,Esophageal Foreign Bodies,Treatment Many foreign bodies pass spontaneously, and mil

8、d symptoms may be secondary to local trauma, rather than an actual foreign body. Foreign bodies that fail to pass into the stomach are usually trapped in the cervical portion of the esophagus below the cricopharyngeus muscle. If the foreign body reaches the stomach, it will, in most cases, pass comp

A meat bolus lodged in the esophagus can sometimes be pushed into the stomach or removed endoscopically, but do not use a meat tenderizer After initial resolution

14、trate Try packing nose lightly with Surgicel or gelfoam sponges soaked with topical vasoconstrictor. Avoid packing patients with coagulapathies who will invariably re-bleed when the packing is removed. Vigorous bleeds must be packed. Need good lighting and instruments for an adequate packing. Intran

Cover with antibiotics to prevent sinusitis If packing fails vessels must be ligated. If the responsible vess

Failure of middle ear ventilation leads to negative pressure relative to the outside environment. Pathogenesis: TM and mucosa retract toward mid
