Extraluminal perforation complicating foreign bodies in the upper aerodigestive tract.
OBJECTIVE
Ingestion of a foreign body is a common problem in nearly all otolaryngology practices. One of the uncommon complications of ingested foreign bodies is penetration and migration of the object, which may lead to serious morbidity and/or death. This study will evaluate the presentation, complications, and management of different sites of penetration.


METHODS
We present a retrospective study of a series of 11 patients who presented with a penetrating foreign body of the upper aerodigestive tract in the past 10 years.


RESULTS
All of the patients had radiologic evidence of a foreign body, but negative findings on rigid endoscopy. A computed tomographic scan was done to confirm the presence of a penetrating foreign body. The foreign body was lodged in the extrapharyngeal tissue in 6 patients, was lodged in the upper thyroid pole in 2 patients, had penetrated a Zenker's diverticulum in 2 patients, and had migrated to the thoracic retroesophageal tissue in 1 patient. All patients underwent extraction of the foreign body by an external approach.


CONCLUSIONS
Although the occurrence is rare, impacted foreign bodies in the upper digestive tract can perforate and migrate into the soft tissue of the neck. In the presence of negative findings on endoscopy, a computed tomographic scan of the neck is essential for the prompt diagnosis and management of perforating foreign bodies.
